Associations Between Kratom-Related State Policy Environments and Kratom Use in a Nationally Representative Population in the United States

Ecological Momentary Assessment of Self-Reported Kratom Use, Effects, and Motivations Among US Adults

Importance

Kratom products, which are sold legally in most of the US, contain alkaloids with opioidergic, adrenergic, and serotonergic activity. Millions of people use kratom to relieve pain, improve mood, or self-manage substance use disorders (SUDs). Kratom use has primarily been examined via surveys, in which recall biases among satisfied users may lead to minimization of transient negative outcomes. Further prospective study of kratom use, such as with ecological momentary assessment (EMA), is needed.

Objective

To characterize proximal motivators, effects, and patterns of kratom use and to assess whether use frequency is associated with motivations, effects, past-year criteria for SUD for kratom (KUD), or other substance use.

Design, Setting, and Participants

For this prospective cross-sectional study, an intensive longitudinal smartphone-based EMA in which participants' current behaviors and experiences were repeatedly sampled in real time was conducted between July 1 and October 31, 2022. Participants comprised a convenience sample of US adults who used kratom at least 3 days per week for at least 4 weeks at the time of online screening. Criteria for past-year KUD were based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Data analysis was performed between November 2022 and November 2023.

Exposure

The exposure was 13 401 kratom-use events across 15 days.

Main Outcomes and Measures

A baseline survey covering demographics, health, kratom attitudes and behaviors, use motivations, other substance use, and KUD was administered before EMA. Data for the following EMA entries were then collected: event-contingent entries for kratom use (product, dose, and proximal motivations), follow-up entries (short-term effects and consequences of use events), random-prompt entries (mood), beginning-of-day entries (effects of kratom on sleep), and end-of-day entries (daily subjective descriptions of kratom effects). Bayesian regression was used to estimate means and credible intervals.

Results

A total of 357 participants completed the EMA. Their mean (SD) age was 38.0 (11.1) years; more than half were men (198 [55.5%]). Participants reported overall motivators of use on the baseline survey that involved managing psychiatric and SUD problems, but proximal motivators evaluated during the EMA involved situation-specific needs such as increasing energy and productivity and decreasing pain. Acute effects were considered congruent with daily obligations. Use patterns, despite having some distinguishing features, were generally similar in their motivators and effects; participants used kratom predominantly during the daytime and seemed to find use frequencies that suited their needs. Higher use patterns were associated with symptoms of physical dependence (eg, withdrawal or tolerance). Co-used substances included caffeine, nicotine, vitamins, and cannabis.

Conclusions and Relevance

Most participants in this study reported using kratom in a seemingly nonproblematic way. When such use appeared problematic, the key element was usually that withdrawal avoidance became a proximal motivator. Longitudinal studies examining changes in kratom use patterns and effects over time are needed.

Treatment of poppy seed tea misuse with buprenorphine in a telehealth practice: a case series

BACKGROUND

Poppy seed tea (PST) is a legally obtainable source of opiates made from the seeds of the opium poppy. Our large telehealth opioid use disorder (OUD) provider group has treated several patients with PST misuse.

METHODS

We retrospectively identified patients with primary PST use disorder treated with buprenorphine in a telehealth-only practice with first visits between January 2021 and December 2022. Patients were identified by having the word "poppy" in their enrollment note, and then charts were reviewed to determine which patients had primary PST misuse. Demographics, buprenorphine doses, and retention in treatment were recorded.

RESULTS

We identified 18 patients treated for PST use disorder. Fifteen (83.3%) identified as male, mean age was 40.4 (standard deviation 8.8) years, and patients resided in 10 different U.S. states. Median starting buprenorphine dose was 2 mg (interquartile range (IQR) 2-2.5 mg). Median stabilizing dose of buprenorphine was 16 mg daily (IQR 15-20.5 mg). As of June 2023, 5 patients (27.8%) were still in active treatment. Two patients (11.1%) had completed a planned, elective taper. Ten patients (55.6%) had unplanned discontinuation from treatment, and 3 patients (16.7%) discontinued for other reasons.

CONCLUSIONS

To our knowledge, this is the largest case series describing PST misuse in the U.S., and the first to demonstrate its treatment in the telehealth setting. PST use disorder is treatable with buprenorphine with doses similar to treatment of other opioid use disorders. Clinicians who treat patients with OUD should be aware of PST use disorder and its treatment.
