Abstract
OBJECTIVE The aim of this study was to assess national trends in recreational and suicidal ingestions of over-the-counter cough preparations that contain Coricidin. METHODS Using the American Association of Poison Control Center's National Poison Data System, we obtained data from 2004 to 2017 on patients aged 13 to 19 years with an ingestion of "Coricidin." We examined trends over time overall and ingestion intent (recreational vs suicidal) using linear regression. We compared patient characteristics, substances ingested, clinical effects and therapies, and outcomes by suicidal versus misuse or recreational intention. RESULTS An initial search with the inclusion criteria found 19,213 calls that matched study inclusion criteria. On average, there was a yearly linear increase of 180.0 (95% confidence interval [CI], 136.6-223.3; P < 0.01) ingestions per year. Within suicide ingestions, there was an average yearly increase of 97.9 (95% CI, 66.9-128.9; P < 0.01) ingestions, and within misuse/recreational ingestions, there was an average yearly increase of 82.1 (95% CI, 60.3-103.9; P < 0.01) ingestions. The most common clinical effect was tachycardia, which occurred in 42.4% of ingestions. Altered mental status, mydriasis, and ataxia were all more common in misuse/recreational ingestions. Suicidal ingestions resulted in more hospital admissions and need for medical treatment. Recreational-use coded calls peaked in 2013, whereas calls coded for suicide attempts have continued to rise dramatically, with a 50% increase in the 14-year study period. CONCLUSION Combination Coricidin products are a major source of morbidity in adolescents. Targeted preventive measures in primary care offices or larger-scale policy/legislative efforts may be helpful to address this.

Abstract
The use of over-the-counter medications as recreational drugs of abuse in adolescents is increasing. We present the case of a patient who presented with abdominal pain after the ingestion of Coricidin®, an over-the-counter cold medication that contains acetaminophen, chlorpheniramine maleate, and dextromethorphan hydrobromide. The case was complicated by acute liver failure and concomitant pancreatitis that, in a few reported cases, has been associated with high doses of acetaminophen.

Abstract
Adolescent substance abuse remains common, with almost a third of adolescents admitting to ethanol use, and a quarter admitting to illicit drug use. It is essential for pediatricians to regularly screen adolescent patients for substance use, because early initiation of drug use has been associated with physical, behavioral, and social health risks. Adolescents abuse what is common and readily available; this includes ethanol, over-the-counter products, marijuana, and inhalants. The most common and effective clinical treatments for significant toxicity from substances of abuse is symptomatic and supportive care including hemodynamic support, respiratory support, and sedation to control psychomotor agitation.

Abstract
Inhalant abuse is the intentional inhalation of a volatile substance for the purpose of achieving an altered mental state. As an important, yet underrecognized form of substance abuse, inhalant abuse crosses all demographic, ethnic, and socioeconomic boundaries, causing significant morbidity and mortality in school-aged and older children. This review presents current perspectives on epidemiology, detection, and clinical challenges of inhalant abuse and offers advice regarding the medical and mental health providers' roles in the prevention and management of this substance abuse problem. Also discussed is the misuse of a specific "over-the-counter" dissociative, dextromethorphan.

Abstract
Dextromethorphan (DXM) in combination with antihistamines and/or pseudoephedrine is widely available as an over-the-counter remedy commonly used for relief of colds and cough. In supratherapeutic amounts, DXM can be extremely activating. These cough preparations have been adopted by many young users of recreational drugs for their psychoactive effects. When used in amounts exceeding those recommended, this practice, known as "robotripping," may result in a manic toxidrome of psychomotor agitation, hostility, grandiose behavior, hallucinations, paranoia, and panic. A case illustration of this phenomenon is described and implications of this phenomenon discussed. There are few reports associating DXM use with bipolar symptomatology.

Abstract
Dextromethorphan (DXM) is a widely available antitussive that has, at elevated dose levels, euphoric and dissociative effects. This article presents the reported patterns and preferences of DXM use, and perceptions of DXM use among adult members of an online DXM community. Analyses were conducted of quantitative and qualitative responses from nine female and 43 male individuals, aged 18-63 years old. All respondents reported illegal and DXM drug use, beginning, on average, at 15.7 and 17.1 years of age, respectively. The majority of respondents first heard about DXM online or from a friend, preferred to use DXM alone, ingested substances concurrently with DXM to modify its effects, had not been to an emergency room or arrested because of their DXM use, and used DXM for its dissociative and mind-altering effects. DXM was perceived as safe and in no need of further regulation with only 14% of respondents mentioning DXM's addictive qualities. Findings from this sample of adult DXM users reveal a sophisticated subculture in which users report using DXM specifically to induce changes to their mental state and use a variety of substances to modify or enhance DXM's effects.

Abstract
Purpose
– The misuse of pharmaceutical opioid analgesics is identified as a global public health concern. Codeine represents an interesting quandary in terms of its regulated status, with individuals varying in their metabolism of codeine, estimation of safe dosages, risk of adverse health consequences and abuse potential. Efforts to quantify and address hidden non-compliant medical codeine use, overuse and intentional misuse is compromised by availability to the public in prescribed and over the counter forms. The paper aims to discuss these issues.
Design/methodology/approach
– A review of literature on codeine use, misuse and dependence, and associated innovative medical and pharmacy interventions is presented, and was conducted as part of a larger scoping review on codeine.
Findings
– The review highlights the complexities associated with monitoring public health awareness of codeine's abuse potential, and customer/patients trends in non-compliant codeine use for therapeutic and recreational purposes. Aberrant codeine behaviours centre on visiting multiple doctors for prescriptions, repeated lost or stolen prescriptions, forging prescriptions and use of multiple pharmacies. Innovations to monitor misuse of codeine include national prescription databases and recent developments in real-time monitoring of dispensing activity.
Practical implications
– Further development of real-time monitoring processes with process evaluation is advised.
Originality/value
– This viewpoint is intended to demonstrate how efforts to quantify and address codeine use are compromised by its availability. It intends to encourage further policy and practitioner dialogue on how to monitor, support and intervene with consumers misusing codeine.

Abstract
Introduction: We describe a patient scheduled for elective surgery who regularly consumed approximately 12 to 15 times the maximum recommended daily dose of dextromethorphan. We describe the clinical pharmacology of dextromethorphan and discuss its anesthetic implications. Case Presentation: A 30-year-old man with a history of a nasal fracture was scheduled to undergo an elective septorhinoplasty. He reported daily consumption of large quantities (1440 to 1800 mg) of dextromethorphan for six years. He was previously treated for dextromethorphan dependency on several occasions with urine dextromethorphan levels exceeding 2000 ng/mL. He described marked dissociative effects when abusing the drug, but had abstained from use for 48 hours before his elective surgery. Considering that dextromethorphan has a relatively short half-life and that the patient did not suffer major withdrawal symptoms after voluntarily discontinuing the drug, the authors proceeded with the case while recognizing that the drug has significant neuropsychiatric and sympathetic nervous system stimulant effects resulting from its actions as a N-methyl-D-aspartate receptor antagonist. Conclusions: Anesthesiologists need to be aware of dextromethorphan’s clinical pharmacology because recreational abuse of the drug has become increasingly common in adolescents and young adults.

Abstract
Detailed data on the recreational use of drugs are difficult to obtain through traditional means, especially for substances like Dextromethorphan (DXM) which are available over-the-counter for medicinal purposes. In this study, we show that information provided by commenters on YouTube is useful for uncovering the toxicologic effects of DXM. Using methods of computational linguistics, we were able to recreate many of the clinically described signs and symptoms of DXM ingestion at various doses, using information extracted from YouTube comments. Our study shows how social networks can enhance our understanding of recreational drug effects.

Abstract
BACKGROUND Prescription drug abuse is a critical problem in the USA and has been linked to more deaths than automobile accidents. Despite this growing epidemic, the USA lacks a timely early warning system. Poison centers (PCs) have the potential to act as sentinel reporting entities for prescription drug abuse and misuse due to near-real-time data reporting and abundant coverage in the USA. METHODS Data from the Researched Abuse, Diversion and Addiction-Related Surveillance (RADARS®) System PC program were compared with data from the Drug Abuse Warning Network (DAWN) from 2004 through 2010. Population rates of PC call mentions regarding abuse and misuse of prescription opioids were compared with population rates of emergency department visit mentions of the same using linear regression. Products included in the analysis were the following: buprenorphine, fentanyl, hydrocodone, hydromorphone, methadone, morphine, and oxycodone. RESULTS The strength of association between RADARS System PC data and DAWN emergency department visits regarding all opioids in aggregate was strong (R² = 0.81, p < 0.001). The correlations between the two programs at the drug class level also were strong for buprenorphine, hydrocodone, hydromorphone, methadone, and oxycodone (all R² > 0.70, all p < 0.01), significant for fentanyl (p = 0.05), and moderate for morphine (p = 0.09). CONCLUSIONS Data on prescription opioid drug abuse from the RADARS System PC program correlates well with emergency room data from DAWN. Due to timeliness of data, geographic coverage and strong associations with other warning systems, PC data can be used for sentinel reporting on prescription drug abuse and misuse in the USA.

Abstract
BACKGROUND The sale of over-the-counter (OTC) medicines from pharmacies can help individuals self-manage symptoms. However, some OTC medicines may be abused, with addiction and harms being increasingly recognised. This review describes the current knowledge and understanding of OTC medicine abuse. APPROACH Comprehensive search of international empirical and review literature between 1990 and 2011. FINDINGS OTC MEDICINE ABUSE WAS IDENTIFIED IN MANY COUNTRIES AND ALTHOUGH IMPLICATED PRODUCTS VARIED, FIVE KEY GROUPS EMERGED: codeine-based (especially compound analgesic) medicines, cough products (particularly dextromethorphan), sedative antihistamines, decongestants and laxatives. No clear patterns relating to those affected or their experiences were identified and they may represent a hard-to-reach group, which coupled with heterogeneous data, makes estimating the scale of abuse problematic. Associated harms included direct physiological or psychological harm (e.g. opiate addiction), harm from another ingredient (e.g. ibuprofen-related gastric bleeding) and associated social and economic problems. Strategies and interventions included limiting supplies, raising public and professional awareness and using existing services and Internet support groups, although associated evaluations were lacking. Terminological variations were identified. CONCLUSIONS OTC medicine abuse is a recognised problem internationally but is currently incompletely understood. Research is needed to quantify scale of abuse, evaluate interventions and capture individual experiences, to inform policy, regulation and interventions.

Abstract
Purpose There are more drug overdose deaths in the Untied States than motor vehicle fatalities. Yet the US vital statistics reporting system is of limited value because the data are delayed by four years. Poison centers report data within an hour of the event, but previous studies suggested a small proportion of poisoning deaths are reported to poison centers (PC). In an era of improved electronic surveillance capabilities, exposure calls to PCs may be an alternate indicator of trends in overdose mortality. Methods We used PC call counts for methadone that were reported to the Researched Abuse, Diversion and Addiction-Related Surveillance (RADARS®) System in 2006 and 2007. US death certificate data were used to identify deaths due to methadone. Linear regression was used to quantify the relationship of deaths and poison center calls. Results Compared to decedents, poison center callers tended to be younger, more often female, at home and less likely to require medical attention. A strong association was found with PC calls and methadone mortality (b = 0.88, se = 0.42, t = 9.5, df = 1, p<0.0001, R2 = 0.77). These findings were robust to large changes in a sensitivity analysis assessing the impact of underreporting of methadone overdose deaths. Conclusions Our results suggest that calls to poison centers for methadone are correlated with poisoning mortality as identified on death certificates. Calls received by poison centers may be used for timely surveillance of mortality due to methadone. In the midst of the prescription opioid overdose epidemic, electronic surveillance tools that report in real-time are powerful public health tools.

Abstract
Children's misuse of harmful legal products (HLPs), including inhaling or ingesting everyday household products, prescription drugs, and over-the-counter drugs, constitutes a serious health problem for American society. This article presents a community prevention model (CPM) focusing on this problem among pre and early adolescents. The model, consisting of a community mobilization strategy and environmental strategies targeting homes, schools, and retail outlets, is designed to increase community readiness and reduce the availability of HLPs, which is hypothesized to reduce HLPs use among children. The CPM is being tested in Alaskan rural communities as part of an inprogress eight-year National Institute on Drug Abuse randomized-controlled trial. This paper presents the CPM conceptual framework, describes the model, and highlights community participation, challenges, and lessons learned from implementation of the model over a 21-month period.

Abstract
Dextromethorphan abuse is increasing in United States. Intentional misuse or abuse ingestions of dextromethorphan-containing products reported to Texas poison centers during 2000-2009 were identified and the distribution of ingestions by selected factors was determined. There were 3,421 total cases; Coricidin® (Schering-Plough Health Care Products, Inc., Memphis, TN) products were involved in 53.6% of cases. The number of cases increased during 2000-2002 and then declined during 2003-2005 before increasing again in 2006 and remaining relatively constant afterward. The majority of patients were male (60.4%) and between 13 and 19 years of age (69.0%). A potentially serious outcome was assigned in 46.2% of the cases and 83.1% were managed at a health care facility.

Abstract
Dexmedetomidine is an α2-adrenergic agonist that is approved by the Food and Drug Administration for the provision of short term (less than 24 hours) sedation of adults during mechanical ventilation. Given its beneficial physiologic effects including sedation and anxiolysis, various applications have been reported in the pediatric-aged patient. We report the use of dexmedetomidine to control the agitation and violent behavior which resulted from the ingestion of illicit drugs in 3 adolescents. The utility of dexmedetomidine in these scenarios is discussed and its potential beneficial effects on cardiovascular and respiratory function are reviewed.

Abstract
OBJECTIVE Variation in the activity of cytochrome P450 2D6 (CYP2D6) affects the pharmacokinetics and effectiveness of dextromethorphan (DM), because it controls the production of dextrorphan, an active metabolite, with higher affinity for the NMDA receptor than the parent compound. This study examined whether pharmacological inhibition of CYP2D6 activity with quinidine would mimic the genetic mutation and thus also alter the psychoactive effects of DM. METHODS In a single-blind, within-subjects study, eight healthy volunteers (all homozygous for the wild type allele for CYP2D6) received placebo and varying doses of DM, both with and without quinidine pre-treatment. Pharmacokinetic and pharmacodynamic measures were assessed at baseline and every hour post-drug for 6 h. RESULTS Compared to the no quinidine condition, quinidine pre-treatment decreased the area under the dose-response curve on subjective measures of positively reinforcing effects (e.g., euphoria, p < 0.04; drug liking, p < 0.05), and was significantly greater for measures of dysphoria (e.g., unpleasantness, p < 0.02). These changes corresponded to increased DM and decreased dextrorphan plasma concentrations. CONCLUSIONS Compared to DM alone, quinidine pre-treatment inhibited DM metabolism and changed its subjective effects, demonstrating that the psychoactive properties of DM are a function of drug metabolism. These results demonstrate the relationship between CYP2D6 activity, plasma drug levels, and psychoactive drug effects, and have implications for both the abuse liability and therapeutic utility of DM.

Abstract
Dextromethorphan is a nonprescription antitussive which has been gaining in popularity as an abused drug, because of the hallucinogenic, dissociative, and intoxicating effects it produces at high doses. This report describes a series of eight drivers arrested for driving under the influence of the combined effects of dextromethorphan and chlorpheniramine, and a further four drivers under the influence of dextromethorphan alone. In the combined dextromethorphan/chlorpheniramine cases, blood dextromethorphan concentrations ranged from 150 to 1220 ng/mL (n = 8; mean 676 ng/mL, median 670 ng/mL), and chlorpheniramine concentrations ranged from 70 to 270 ng/mL (n = 8; mean 200 ng/mL, median 180 ng/mL). The four cases without chlorpheniramine present had blood dextromethorphan concentrations between 190 and 1000 ng/mL (mean 570 ng/mL, median 545 ng/mL). Some drivers had therapeutic concentrations of other drugs present. Drivers generally displayed symptoms of central nervous system (CNS) depressant intoxication, and there was gross evidence of impairment in their driving, including weaving, leaving the lane of travel, failing to obey traffic signals, and involvement in collisions. Drug Recognition Expert opinions confirmed that the subjects were under the influence of a drug in the CNS-depressant category.

Abstract
OBJECTIVE To describe the epidemiology, patient presentation, and clinical management associated with dextromethorphan (DM) abuse. DATA SOURCES PubMed/Medline search using terms dextromethorphan and abuse through July 2008, bibliographies of selected publications, epidemiology tracking databases. STUDY SELECTION By the authors. DATA EXTRACTION English language-published review articles, clinical trials, and case reports that described the epidemiologic and toxicologic profile of DM were included. DATA SYNTHESIS DM is a relatively inexpensive and easily accessible over-the-counter (OTC) medication intended for use as an antitussive. Increasingly, illicit use of the drug has been reported. At clinical doses, the drug produces few adverse effects. However, when abused in large quantities (>2 mg/kg), the drug has been associated with a dissociative effect similar to those described by ketamine and phencyclidine abusers. Massive ingestions of the drug may be associated with untoward effects, including tachycardia, hypertension, and respiratory depression. Overdose symptoms may also be associated with coformulated products such as antihistamines and sympathomimetic amines. Management is primarily supportive. Naloxone has been used to manage DM toxicity but with conflicting reports of effectiveness. CONCLUSION Recent reports indicate that DM is often abused by individuals seeking its dissociative effects. Clinicians should be aware of the abuse potential of DM. Pharmacists might be particularly cognizant of the risks involved with DM abuse as they control OTC access to the drug.

Abstract
Histamine H1 receptor antagonists can be sedating and have behavioral effects, including reinforcing and discriminative stimulus effects in non-humans, that predict abuse liability. Previous research has suggested that antihistamines can enhance the effects of some drugs of abuse. We have reported a synergistic interaction between cocaine and diphenhydramine (DPH) in a self-administration assay with monkeys. The present study was designed to extend those findings to other combinations of cocaine and DPH, and to the mixture of cocaine and another H1-antihistamine, pyrilamine. Rhesus monkeys were prepared with chronic i.v. catheters and allowed to self-administer cocaine, DPH or pyrilamine alone or as mixtures under a progressive-ratio schedule of reinforcement. Cocaine, DPH and pyrilamine alone maintained self-administration and cocaine was the stronger reinforcer. When cocaine was combined with DPH or pyrilamine in a 1:1, 1:2 or 2:1 ratio of the ED(50)s, the combinations were super-additive as reinforcers. Reinforcing strength of the combinations was greater than that of the antihistamines alone but not greater than cocaine. The data support the prediction that the combination of cocaine and histamine H1 receptor antagonists could have enhanced potential for abuse relative to either drug alone. The interaction may involve dopamine systems in the CNS.

Abstract
The objective of this guideline is to assist poison center personnel in the appropriate out-of-hospital triage and initial out-of-hospital management of patients with a suspected ingestion of dextromethorphan by 1) describing the process by which an ingestion of dextromethorphan might be managed, 2) identifying the key decision elements in managing cases of dextromethorphan ingestion, 3) providing clear and practical recommendations that reflect the current state of knowledge, and 4) identifying needs for research. This guideline applies to the ingestion of dextromethorphan alone. Co-ingestion of additional substances could require different referral and management recommendations depending on the combined toxicities of the substances. This guideline is based on an assessment of current scientific and clinical information. The expert consensus panel recognizes that specific patient care decisions might be at variance with this guideline and are the prerogative of the patient and the health professionals providing care, considering all of the circumstances involved. This guideline does not substitute for clinical judgment. The grade of recommendation is in parentheses. 1) All patients with suicidal intent, intentional abuse, or in cases in which a malicious intent is suspected (e.g., child abuse or neglect) should be referred to an emergency department (Grade D). 2) Patients who exhibit more than mild effects (e.g., infrequent vomiting or somnolence [lightly sedated and arousable with speaking voice or light touch]) after an acute dextromethorphan ingestion should be referred to an emergency department (Grade C). 3) Patients who have ingested 5-7.5 mg/kg should receive poison center-initiated follow-up approximately every 2 hours for up to 4 hours after ingestion. Refer to an emergency department if more than mild symptoms develop (Grade D). 4) Patients who have ingested more than 7.5 mg/kg should be referred to an emergency department for evaluation (Grade C). 5) If the patient is taking other medications likely to interact with dextromethorphan and cause serotonin syndrome, such as monoamine oxidase inhibitors or selective serotonin reuptake inhibitors, poison center-initiated follow-up every 2 hours for 8 hours is recommended (Grade D). 6) Patients who are asymptomatic and more than 4 hours have elapsed since the time of ingestion can be observed at home (Grade C). 7) Do not induce emesis (Grade D). 8) Do not use activated charcoal at home. Activated charcoal can be administered to asymptomatic patients who have ingested overdoses of dextromethorphan within the preceding hour. Its administration, if available, should only be carried out by health professionals and only if no contraindications are present. Do not delay transportation in order to administer activated charcoal (Grade D). 9) For patients who have ingested dextromethorphan and are sedated or comatose, naloxone, in the usual doses for treatment of opioid overdose, can be considered for prehospital administration, particularly if the patient has respiratory depression (Grade C). 10) Use intravenous benzodiazepines for seizures and benzodiazepines and external cooling measures for hyperthermia (>104 degrees F, >40 degrees C) for serotonin syndrome. This should be done in consultation with and authorized by EMS medical direction, by a written treatment protocol or policy, or with direct medical oversight (Grade C). 11) Carefully ascertain by history whether other drugs, such as acetaminophen, were involved in the incident and assess the risk for toxicity or for a drug interaction.

Abstract
The pattern of activation of dopamine (DA) neurotransmission in the nucleus accumbens (NAc) of rats produced by H(1) histamine antagonists which have behavioral effects like those of psychostimulant drugs was examined. Diphenhydramine and (+)-chlorpheniramine were compared with triprolidine, a potent and selective H(1) antagonist and (-)-chlorpheniramine which is less active than its enantiomer at H(1) receptors. Affinities of the drugs to DA, serotonin, and norepinephrine transporters at H(1) receptors and potencies for DA uptake inhibition in striatal synaptosomes were determined to assess mechanisms by which the compounds increased DA levels. Intravenous diphenhydramine (1.0-3.0 mg/kg) (+)- and (-)-chlorpheniramine (1.0-5.6 mg/kg) but not triprolidine (1.0-3.0 mg/kg) elicited a cocaine-like pattern of stimulation of DA transmission with larger effects in the NAc shell than core. The absence of stereospecific effects with chlorpheniramine enantiomers along with the lack of an effect with triprolidine suggest that the effects on DA transmission were not related to H(1) receptor antagonism. Although in vivo potencies were not directly related to DA transporter affinities, it is hypothesized that actions at that site modulated by other actions, possibly those at the serotonin transporter, are primarily responsible for the neurochemical actions of the drugs on DA neurotransmission and might underlie the occasional misuse of these medications.

Abstract
PURPOSE OF REVIEW Prescription and over-the-counter cough and cold medication abuse is rapidly becoming a national health concern for adolescents. Increased awareness of this growing epidemic is essential toward diagnosing, treating and preventing this type of substance abuse. RECENT FINDINGS Data from surveys and poison control center records demonstrate an increased nonmedical use of prescription and over-the-counter cough and cold preparations, particularly those containing dextromethorphan. The nonmedical use of prescription medications may result in serious clinical effects with potential life-threatening complications, dependence and withdrawal syndromes. Dextromethorphan causes alterations in mental status that may contribute to judgment impairment leading to injury or fatality. Co-ingestion of other substances found in over-the-counter medications may also cause significant morbidity. Alcohol and illicit drug use is highly associated with the abuse of these medications. The incentive for abuse, such as easy accessibility, low cost and decreased perception of potential for harm, and potential interventions are described. SUMMARY The recent trend of prescription and dextromethorphan-containing over-the-counter medication abuse in adolescents is alarming. Improved awareness for these readily available, seemingly benign yet highly dangerous medications is essential. Prevention and early education on substance abuse in young teens are critical in combating this recent epidemic.

Abstract
OBJECTIVES To analyze the trend of dextromethorphan abuse in California and to compare these findings with national trends. DESIGN A 6-year retrospective review. SETTING California Poison Control System (CPCS), American Association of Poison Control Centers (AAPCC), and Drug Abuse Warning Network (DAWN) databases from January 1, 1999, to December 31, 2004. PARTICIPANTS All dextromethorphan abuse cases reported to the CPCS, AAPCC, and DAWN. The main exposures of dextromethorphan abuse cases included date of exposure, age, acute vs long-term use, coingestants, product formulation, and clinical outcome. Main Outcome Measure The annual proportion of dextromethorphan abuse cases among all exposures reported to the CPCS, AAPCC, and DAWN databases. RESULTS A total of 1382 CPCS cases were included in the study. A 10-fold increase in CPCS dextromethorphan abuse cases from 1999 (0.23 cases per 1000 calls) to 2004 (2.15 cases per 1000 calls) (odds ratio, 1.48; 95% confidence interval, 1.43-1.54) was identified. Of all CPCS dextromethorphan abuse cases, 74.5% were aged 9 to 17 years; the frequency of cases among this age group increased more than 15-fold during the study (from 0.11 to 1.68 cases per 1000 calls). Similar trends were seen in the AAPCC and DAWN databases. The highest frequency of dextromethorphan abuse occurred among adolescents aged 15 and 16 years. The most commonly abused product was Coricidin HBP Cough & Cold Tablets. CONCLUSIONS Our study revealed an increasing trend of dextromethorphan abuse cases reported to the CPCS that is paralleled nationally as reported to the AAPCC and DAWN. This increase was most evident in the adolescent population.

Abstract
Youth use of harmful legal products, including inhaling or ingesting everyday household products, prescription drugs, and over-the-counter drugs, constitutes a growing health problem for American society. As such, a single targeted approach to preventing such a drug problem in a community is unlikely to be sufficient to reduce use and abuse at the youth population level. Therefore, the primary focus of this article is on an innovative, comprehensive, community-based prevention intervention. The intervention described here is based upon prior research that has a potential of preventing youth use of alcohol and other legal products. It builds upon three evidence-based prevention interventions from the substance abuse field: community mobilization, environmental strategies, and school-based prevention education intervention. The results of a feasibility project are presented and the description of a planned efficacy trial is discussed.

Abstract
AIMS Since the publication of the Diagnostic and Statistical Manual of Mental Disorders fourth edition (DSM-IV), many studies have addressed substance use disorders (SUD) in adolescents. Based on that adolescent literature, this paper suggests further research to help guide decisions about revising for DSM-V the SUD criteria in DSM-IV. METHODS The author has reviewed the 'Substance Related Disorders' section of DSM-IV-TR, recalled his experience in helping to draft that section, accessed relevant articles in PubMed and reviewed his own extensive file of literature citations. RESULTS This paper suggests six questions for adolescent research to help guide the framers of DSM-V's 'Substance Related Disorders' section: (a) DSM-IV did not provide a diagnosis of cannabis withdrawal; should DSM-V continue that position? (b) Should SUD be included or referenced among 'Disorders Usually First Diagnosed in Infancy, Childhood, or Adolescence'? (c) Can inter-rater reliability of the substance abuse (SA) criteria be improved with altered example situations, text descriptions or phrasing of the current criteria? (d) Between ages 14 and 18 years is earlier onset of SUD a severity marker that could be incorporated into DSM-V as a predictor of worse course? (e) In DSM-V could a phenotypic descriptor of pathological multi-substance involvement document severity and predict course of SUD? (f) Could clinicians and patients benefit from DSM-V-related postpublication procedures for classifying emerging new drugs into DSM-V's categories? CONCLUSIONS Without substantive changes in SA or substance dependence diagnostic criteria, research may improve the usefulness of those criteria for adolescents.

Abstract
PURPOSE OF REVIEW Over-the-counter cough and cold medicines are widely prescribed by general pediatricians in order to relieve cough and other symptoms in the setting of upper respiratory infections. This article will review the pharmacologic components found in over-the-counter cough medicines, the data concerning their use and efficacy in children, the increasing trend of abuse of these medications, and their potential toxicity. RECENT FINDINGS There is an overall paucity of data evaluating the use of over-the-counter cough medicines in children as well as a lack of evidence for their efficacy. The articles cited will review the efficacy of over-the-counter cough medicines, the emerging trend of abuse of certain preparations such as dextromethorphan, and specific cases of morbidity and even mortality. SUMMARY According to the limited data that exist, there is not any evidence that over-the-counter cough and cold medicines are effective in children. In otherwise healthy children without chronic complicating factors such as asthma, the symptoms of acute upper respiratory infections are generally mild and self-limited. Pediatricians must weigh the benefits against the potential risks of recommending over-the-counter cough medicines and should be prepared to educate parents about the expected natural course of their child's illness and the likelihood that these medications will be minimally effective in relieving symptoms, if at all.

Abstract
Dextromethorphan hydrobromide (DXM), a constituent of more than 125 patent cough/cold remedies, is the most popular antitussive medication in the United States. Cough syrups or capsules also contain additional ingredients such as acetaminophen, chlorpheniramine maleate, guaifenesin, and/or pseudoephedrine, and toxicity with overdosage is additive to that of dextromethorphan alone. An unknown number of adolescents in the United States and Europe intoxicate themselves with acute megadoses of dextromethorphan. A megadose of DXM is defined as 5 to 10 times the dose recommended for control of annoying nonproductive coughs. Although a moderate overdose of pure DXM hydrobromide is free of serious adverse effects, approximately 5% of persons of European ethnicity lack the ability to metabolize the drug normally, leading to rapid acute toxic levels. Variable quantities of pure dextromethorphan powder in multiples of 1 gram are easily available from the worldwide web, including e-Bay. Recipe-like extraction procedures are quickly available on the Internet for seemingly simple and inexpensive home manufacture of concentrated dextromethorphan powder from Coricidin HBP Cough & Cold tablets (street name triple C). Adolescents intoxicate themselves at parties and even before or after school since the drug is legal, relatively inexpensive, and easily purchased or shoplifted at drug or convenient stores. Acute megadoses of the drug have profound psychological and physiological effects similar to those of phencyclidine (PCP). Megadoses of dextromethorphan used to self-intoxicate, can produce a false-positive screening test for phencyclidine in a urine specimen.

Abstract
Dextromethorphan is an over-the-counter dissociative agent of increasing popularity as a drug of abuse among younger adolescents. The drug produces a range of toxicities depending upon either the dose or the components of the specific formulation that was ingested. Most cases improve with supportive care alone, but severely intoxicated patients may require significant attention. Because dextromethorphan is misused primarily by younger adolescents, the early identification and treatment of dextromethorphan abuse may be important in preventing broader substance abuse in these children. Consequently, it is important for clinicians to recognize, treat, and appropriately refer those who present with intoxication from this drug.

Abstract
The ability of non-competitive NMDA antagonists and other selected compounds to inhibit [3H]MK-801 binding to the NMDA receptor in brain membranes was evaluated in female, dark Agouti rats. In homologous competition binding studies the average apparent affinity (KD) of [3H]MK-801 for its binding site was 5.5 nM and the binding site density (Bmax) was 1.83 pmol/mg protein. Inhibition of [3H]MK-801 binding by non-competitive NMDA antagonists was best described with a one-site competition model and the average Hill coefficients were -1. A series of eight non-competitive NMDA antagonists inhibited [3H]MK-801 binding with the following rank order of affinity (K(i), nM): MK-801 (5.5) > dexoxadrol (21.5) > or = TCP (24.2) > phencyclidine (100.8) > (+)-SKF 10,047 (357.7) > dextrorphan (405.2) > ketamine (922.2) > dextromethorphan (2913). These inhibition binding constants determined in dark Agouti rat brain membranes were significantly correlated (P = 0.0002; r2 = 0.95) with previously reported values determined in Sprague-Dawley rats [Wong et al., 1988, J. Neurochem. 50, 274-281]. Despite significant differences in metabolic capability between these strains, the central nervous system NMDA receptor ion channel shares similar characteristics.

Abstract
During the last few years the term club drugs has been used for defining an heterogeneous group of chemical substances in permanent evolution, that are consumed for recreational purposes. These substances have been extensively used, firstly by the Rave culture and later by the so called Club culture. These movements are characterized by the search of amplified sensations, by means of the combination of electronic music, marathon dancing and substance abuse. After years with a predominating consumption of designer amphetamines in these groups, it seems that the use of another type of substances is increasing, fundamentally drugs with hallucinogenic effects. This review focus in four of these substances; ketamine, dextromethorphan, nitrous oxide and gamma-hydroxybutyric acid (GHB, liquid ecstasy), and includes a discussion of their pharmacology, recreational use, adverse effects and patient management. These drugs are, at he same time, drugs of abuse and medicines with concrete indications in therapeutics, with an important increase of their consumption in the last few years. The Rave and Club cultures are also described.
