Opportunities and challenges in developing orally administered cannabis edibles

Pharmacokinetics and Bioavailability of Cannabinoids Administered via a Novel Orobuccal Nanoparticle Formulation (NanoCelle™) in Patients with Advanced Cancer

Introduction: The administration of cannabinoids for disease and symptom management such as pain continues to elicit significant interest, albeit limited information that is available regarding their pharmacokinetics and pharmacodynamics to guide clinical practice. Cannabis-based medicines contain a wide variety of chemical compounds, of which the most common include the cannabinoids delta-9-tetrahydrocannabinol (Δ9THC), and the nonpsychomimetic cannabidiol (CBD). The pharmacokinetics of cannabis-based medicines and the effects observed depend on the formulation and route of administration. THC and CBD are subject to extensive first-pass hepatic metabolism and pharmacokinetic drug interactions, the latter via inhibition or induction of enzymes and transporters. This study was conducted to describe the pharmacokinetics of CBD, THC, and its metabolites following orobuccal administration, providing pivotal information to guide the clinical development program of a self-assembled micellized nanoparticle formulation containing 1:1 Δ9THC and CBD. Methods: Pharmacokinetic data was obtained from a phase 1, two-stage study in patients with advanced cancer, and modelled using a population pharmacokinetic approach. To provide an indication of predicted exposure with multiple dosing, the final population pharmacokinetic models were used to simulate concentration-time profiles for each of the active compounds. Results: The developed population pharmacokinetic models provided important information on the bioavailability of CBD and THC, with estimated values of 10% and 27%, respectively. These values were approximately two-fold greater than that which has been previously described for oromucosal formulations. Discussion: This enhanced bioavailability can most likely be attributed to the NanoCelle® technology. This technology provides evidence to support the application of this innovative drug delivery platform to overcome limitations associated with cannabinoid administration for therapeutic use.

Twin-screw extrusion retains industrial hemp byproduct (hemp flakes) functionality

Consumer recognition of the health benefits of industrial hemp cannabidiol (CBD) products has increased its value to consumers. Consequently, there is a need to explore industrial hemp byproducts to improve sustainability and foster a circular economy. Extrusion processing was conducted with formulations made with hemp flakes, a byproduct of CBD oil extraction based on corn flour with 5%, 10%, and 15% hemp flakes replacement using a laboratory-scale conical twin-screw extruder. The impacts of formulation, barrel temperature, and screw speed on extrudates were evaluated. Cannabichromene (CBC), cannabinol (CBN), cannabidiolic acid (CBDA), cannabigerol (CBG), and CBD were determined with high-performance liquid chromatography before and postextrusion. Antioxidant potential (total polyphenol content [TPC] and 1,1-diphenyl-1-picrylhydrazyl radical scavenging assay [DPPH]) and ferric-reducing antioxidant potential (FRAP) were determined similarly. Increasing hemp flakes in the formula reduced pasting properties significantly (p ≤ 0.05). Expansion ratio (ER) showed significant linear effects with the amount of hemp flakes in the formula (p ≤ 0.05) and die temperature (p ≤ 0.05), while the 10% hemp formula recorded the highest ER of 3.24 (p ≤ 0.05). Extrusion generally reduced TPC, DPPH, FRAP, and cannabinoids compared to raw formulas. Low screw speeds and medium barrel temperatures displayed high retention of cannabinoids and antioxidants. Low screw speeds might have allowed adequate shearing, mixing, and an extended high-pressure exposure leading to the release of bound polyphenols, antioxidants, and cannabinoids. Some extrusion parameters can maintain cannabinoids and antioxidants in hemp byproducts while transforming them into puffed food products. These findings directly affect the industry, providing valuable insights for practical application. PRACTICAL APPLICATION: Extrusion cooking remains one of the most economical methods of valorizing agricultural byproducts. This work developed extrusion parameters applicable to the food industry for making quality puffed food products. It could apply to snacks, breakfast cereals, animal feed, and others with desirable consumer properties and retained functionality for improving health and wellness.

Impact of Healthcare Provider Awareness and Guidance on the Medical Cannabis Experience

Introduction

Cannabis as a therapeutic agent is accessible to a growing number of people, though research suggests that many medical cannabis (MC) users undertake their cannabinoid therapy independently, without collaborating with a cannabis clinician or informing their primary care provider (PCP). The effects of medical collaboration or disclosure to PCP on outcomes of cannabinoid therapy are unknown. Researchers anticipate that those who collaborate with a cannabis clinician or disclose their medical cannabis use to their PCP will find MC to be more effective, use less delta-9-tetrahydrocannabinol (THC) and more cannabidiol (CBD), and experience fewer side effects.

Methods

Through an online survey, medical cannabis users reported their cannabis usage patterns, health outcomes, PCP awareness, and collaboration with cannabis clinicians. These responses were analyzed using a variety of statistical tests to search for differences in reported efficacy, specific cannabinoid, and side effects between different levels of medical professional involvement (n = 988).

Results

Patients who either worked with a cannabis clinician or reported their use of their PCP reported significantly higher efficacy (p < 0.001), and in the case of working specifically with a cannabis clinician, higher daily doses of cannabidiol were used (p < 0.001). CBD doses did not vary between those who had disclosed their MC use to their PCP and those who had not. There were no significant differences in THC doses or side effects identified between groups.

Conclusion

The results indicated that undertaking cannabinoid therapy with PCP awareness or guidance from a cannabis clinician is associated with better outcomes.

Decoding the Therapeutic Potential of Cannabis and Cannabinoids in Neurological Disorders

For millennia, Cannabis sativa has served diverse roles, from medicinal applications to recreational use. Despite its extensive historical use, only a fraction of its components have been explored until recent times. The therapeutic potential of Cannabis and its constituents has garnered attention, with suggestions for treating various conditions such as Parkinson's disease, epilepsy, Alzheimer's disease, and other neurological disorders. Recent research, particularly on animal experimental models, has unveiled the neuroprotective properties of cannabis. This neuroprotective effect is orchestrated through numerous G protein-coupled receptors (GPCRs) and the two cannabinoid receptors, CB1 and CB2. While the capacity of cannabinoids to safeguard neurons is evident, a significant challenge lies in determining the optimal cannabinoid receptor agonist and its application in clinical trials. The intricate interplay of cannabinoids with the endocannabinoid system, involving CB1 and CB2 receptors, underscores the need for precise understanding and targeted approaches. Unravelling the molecular intricacies of this interaction is vital to harness the therapeutic potential of cannabinoids effectively. As the exploration of cannabis components accelerates, there is a growing awareness of the need for nuanced strategies in utilizing cannabinoid receptor agonists in clinical settings. The evolving landscape of cannabis research presents exciting possibilities for developing targeted interventions that capitalize on the neuroprotective benefits of cannabinoids while navigating the complexities of receptor specificity and clinical applicability.

Long-term stability and bactericidal properties of galenic formulations of Cannabis sativa oils

The long-term stability in real and accelerated time for galenic oils based on full-spectrum cannabis has been studied, using sesame oil as a dilutant. Sesame oil is one of the most used vehicles in the cannabis pharmaceutical industry due to the costs and increased oral bioavailability of cannabinoids. The real-time assays conducted at 25 °C over twelve months demonstrated high stability and showed no significant changes in the composition of cannabinoids, total polyphenols, flavonoids, or antioxidant capacity. In these studies, it was observed that there was no development of microorganisms compromising the stability of the oils over a year. The three oil varieties exhibited a high bactericidal capacity against E. coli, S. aureus, and P. larvae.

CBD oil by-product (Hemp flakes): Evaluation for nutritional composition, heavy metals and functionality as a food ingredient

Background

The recent interest among consumers in industrial hemp due to health and wellness benefits has led to several products from industrial hemp, including cannabidiol (CBD) oil. CBD oil extraction from hemp buds and flowers generates by-product biomass (hemp flakes), often posing disposal challenges and with little or no applications. We hypothesized that hemp flakes possess residual compounds with nutritional and health value that could be used to improve utilization.

Methods

Locally sourced hemp flakes were compared to three commercial hemp protein products. The nutritional composition (proximate analysis), heavy metals (Al, Cu, As, Pb, Co, Cd), and functional composition (phenolic and antioxidant properties-total phenolic compounds (TPC), total flavonoid compounds (TFC), ferric reducing antioxidant potential (FRAP), 1,1-diphenyl-1-picrylhydrazyl (DPPH), Trolox equivalent antioxidant capacity (TEAC)), (CBD, cannabiodiolic acid-CBDA, cannabichromene-CBC, cannabigerol-CBG, and cannabinol-CBN) contents were determined and compared.

Findings

Hemp flakes had a similar nutritional composition to commercial hemp protein products, with heavy metal levels within FDA allowed limits. The by-product had significantly higher CBDA levels than commercial products. Overall, hemp flakes had comparable nutrient composition and antioxidant capabilities. Based on the protein composition of hemp flakes (31.62 %) versus the highest commercial product (43 %), hemp flakes are an acceptable functional food ingredient.

Polycaprolactone microparticles for the subcutaneous administration of cannabidiol: in vitro and in vivo release

Cannabidiol (CBD) has become a highly attractive entity in therapeutics. However, its low aqueous solubility, instability and handling problems limit the development of effective CBD formulations. Subcutaneously administered CBD-loaded polycaprolactone microparticles (MP) represent an interesting strategy to overcome these challenges. This work focuses on evaluating the pharmacokinetics of CBD formulated in polymer microparticles for subcutaneous administration and characterising its release. The mean release time (MRLT) parameter is used to compare the release of CBD from two microparticle formulations in vitro and in a mouse model. After the administration of CBD in solution, a bicompartmental distribution is observed due to the extensive diffusion to the brain, being the brain/blood AUC ratio 1.29. The blood and brain mean residence time (MRT) are 0.507 ± 0.04 and 0.257 ± 0.0004 days, respectively. MP prepared with two drug/polymer ratios (15/150-MP and 30/150-MP) are designed, showing similar in vitro dissolution profiles (similarity factor (f2) is 63.21), without statistically significant differences between MRLTin vitro values (4.68 ± 0.63 and 4.32 ± 0.05 days). However, considerable differences in blood and brain profiles between both formulations are detected. The blood and brain MRT values of 15/150-MP are 6.44 ± 0.3 days and 6.15 ± 0.25 days, respectively, whereas significantly lower values 3.91 ± 0.29 days and 2.24 ± 0.64 days are obtained with 30/150-MP. The extended release of CBD during 10 days after a single subcutaneous administration is achieved.

Galenic formulations of Cannabis sativa: comparison of the chemical properties of extracts obtained by simple protocols using lipidic vehicles

The growing use of Cannabis sativa as a complementary therapy to allopathic medicine has brought about the modification of laws for its use worldwide. This entails the need to harmonize the methods of galenic preparations in pharmacies and cannabis-specialized non-governmental organizations as well as for self-provision as contemplated in some current legislation, such as that of Argentina. Thus, this work aimed to study simple and efficient methods to produce medicinal cannabis oils that require low-cost equipment and few handling steps. The final formulas allowed the obtaining of preparations of known concentrations of neutral cannabinoids, total polyphenol content, total flavonoid content, and antioxidant capacity. These methods allow for the selection of convenient vehicles and access to safe medicinal products of standardized quality. Our results show that cannabis extraction can be efficiently performed by directly using long-chain lipidic vehicles as extractants, resulting in a formulation with maximized oxidizing capacity and potentially extending its durability.

Nanocarriers for Cannabinoid Delivery: Enhancing Therapeutic Potential

Medical cannabis has potential therapeutic benefits in managing pain, anxiety, depression, and neurological and movement disorders. Phytocannabinoids derived from the cannabis plant are responsible for their pharmacological and therapeutic properties. However, the complexity of cannabis components, especially cannabinoids, poses a challenge to effective medicinal administration. Even with the increasing acceptance of cannabis-based medicines, achieving consistent bioavailability and targeted distribution remains difficult. Conventional administration methods are plagued by solubility and absorption problems requiring innovative solutions. After conducting a thorough review of research papers and patents, it has become evident that nanotechnology holds great promise as a solution. The comprehensive review of 36 research papers has yielded valuable insights, with 7 papers reporting enhanced bioavailability, while others have focused on improvements in release, solubility, and stability. Additionally, 19 patents have been analyzed, of which 7 specifically claim enhanced bioavailability, while the remaining patents describe various formulation methods. These patents outline effective techniques for encapsulating cannabis using nanocarriers, effectively addressing solubility and controlled release. Studies on the delivery of cannabis using nanocarriers focus on improving bioavailability, prolonging release, and targeting specific areas. This synthesis highlights the potential of nanotechnology to enhance cannabis therapies and pave the way for innovative interventions and precision medicine.

Hemp-Derived CBD Used in Food and Food Supplements

Cannabis sativa L., a plant historically utilized for textile fibers, oil, and animal feed, is progressively being recognized as a potential food source. This review elucidates the nutritional and functional attributes of hemp and cannabidiol (CBD) within the context of food science. Hemp is characterized by the presence of approximately 545 secondary metabolites, among which around 144 are bioactive cannabinoids of primary importance. The study looks in detail at the nutritional components of cannabis and the potential health benefits of CBD, encompassing anti-inflammatory, anxiolytic, and antipsychotic effects. The review deals with the legislation and potential applications of hemp in the food industry and with the future directions of cannabis applications as well. The paper emphasizes the need for more scientific investigation to validate the safety and efficacy of hemp components in food products, as current research suggests that CBD may have great benefits for a wide range of consumers.

Population Pharmacokinetics of Oral-Based Administration of Cannabidiol in Healthy Adults: Implications for Drug Development

Background and Objectives: Cannabidiol (CBD) is increasingly being studied as a therapeutic option for a range of health conditions; however, the pharmacokinetics of CBD is not well understood. This study characterized CBD pharmacokinetics in healthy adults using a population pharmacokinetic approach, informing drug development of oral-based dose forms of CBD. Materials and Methods: CBD concentration-time data were obtained from a phase I, randomized, open-label, four-way crossover study (n=12) and modeled using Phoenix NLME. Monte Carlo simulations were conducted to estimate CBD exposure with chronic dosing as intended for clinical use (50 mg b.i.d.). Results: A three-compartment pharmacokinetic model with a chain of absorption transit compartments and first-order elimination most adequately described CBD pharmacokinetics. Substantial variability in population pharmacokinetic parameters was identified (up to 60%CV), which could not be accounted for by any covariates. Simulations indicated a 3.6-fold difference in drug exposure at steady state with multiple dosing (AUCτ 95% prediction interval: 65.5-138 ng·h/mL), and variability in the time to reach steady state, which was predicted to be up to ∼3 weeks in some individuals (95% prediction interval: 18.6-297 h). Conclusions: The findings of this study have important implications for drug development. The lack of a clear dose-response relationship, due to large pharmacokinetic variability, indicates that a one-size-fits-all approach to CBD dosing may not be feasible, at least with current dosing approaches. Furthermore, an extended time to reach steady state means that the full effect of a selected dose level is not truly observed for some time and requires careful consideration in trial design.

An Ecological Examination of Indica Versus Sativa and Primary Terpenes on the Subjective Effects of Smoked Cannabis: A Preliminary Investigation

Background: The legal cannabis landscape has greatly outpaced scientific knowledge. Many popular cannabis claims, such as cultivar (colloquially referred to as strain) classification and terpene content producing different subjective effects, are unsubstantiated. This study examined, for the first time, whether cultivar classification (sativa/indica) and terpene content (caryophyllene, limonene, myrcene, pinene, and terpinolene) were associated with subjective cannabis effects (i.e., pain levels, low-arousal ["indica-like"] effects, high-arousal ["sativa-like"] effects, and negative effects). Methods: Regular cannabis users (n=101) took part in a 2-week long ecological momentary assessment study in which they responded to questions about their cannabis use, stated their preference for sativa versus indica, and reported their in-the-moment subjective effects within 30 min of smoking cannabis. Cultivars were coded for sativa versus indica classification and primary terpene content using Leafly, a popular search engine. Linear mixed-effect models then examined subjective response by sativa/indica and primary terpene. Covariates included demographics (age, sex, race, income), cannabis use (medical use, cannabis use frequency, stated preference for sativa/indica, global expected cannabis effects), morning pain ratings, and specific smoked cannabis occasions (hour of day, minutes since use, context, number of hits, and tetrahydrocannabinol). Results: The majority of participants (78.3%) had a preference for either sativa or indica and reported reasons for their preference that aligned with industry claims. After controlling for covariates, findings revealed that cultivars classified as indica dominant were associated with greater low-arousal (e.g., sluggish, slow) effects relative to the unweighted mean of all cannabis cultivars (b = 0.44, SE=0.16, p=0.01). Cultivars with primary caryophyllene were associated with greater pain ratings (b = 0.53, SE=0.24, p=0.03) and negative effects (b = 0.22, SE=0.08, p=0.01) relative to the mean of all other terpene types. Cultivars with primary pinene were associated with less negative effects (b = -0.35, SE=0.18, p=0.04). Conclusions: Cultivars classified as indica dominant were associated with greater low-arousal effects in models that accounted for both within- and between-person variation, despite the scientific challenges distinguishing between sativa and indica. Preliminary findings also suggest terpenes may play a role in subjective effects. These results emphasize the need for further research, particularly controlled lab studies.

Current Challenges and Opportunities for Improved Cannabidiol Solubility

Cannabidiol (CBD), derived from the cannabis plant, has gained significant attention due to its potential therapeutic benefits. However, one of the challenges associated with CBD administration is its low bioavailability, which refers to the fraction of an administered dose that reaches systemic circulation. This limitation necessitates the exploration of various approaches to enhance the bioavailability of CBD, thus helping to maximize its therapeutic potential. A variety of approaches are now emerging, including nanoemulsion-based systems, lipid-based formulations, prodrugs, nanocarriers, and alternative routes of administration, which hold promise for improving the bioavailability of CBD and pave the way for novel formulations that maximize the therapeutic potential of CBD in various medical conditions. This opinion piece presents the current understanding surrounding CBD bioavailability and considers strategies aimed at improving both its absorption and its bioavailability.

"Breaking bud": the effect of direct chemical modifications of phytocannabinoids on their bioavailability, physiological effects, and therapeutic potential

Tetrahydrocannabinol (THC) and cannabidiol (CBD) are the two "major cannabinoids". However, their incorporation into clinical and nutraceutical preparations is challenging, owing to their limited bioavailability, low water solubility, and variable pharmacokinetic profiles. Understanding the organic chemistry of the major cannabinoids provides us with potential avenues to overcome these issues through derivatization. The resulting labile pro-drugs offer ready cannabinoid release in vivo, have augmented bioavailability, or demonstrate interesting pharmacological properties in their own right. This review identifies and discusses a subset of these advanced derivatization strategies for the major cannabinoids, where the starting material is the pure phytocannabinoid itself, and the final product either a cannabinoid pro-drug, or a novel pharmacoactive material.

Structural Investigation of Beta-Cyclodextrin Complexes with Cannabidiol and Delta-9-Tetrahydrocannabinol in 1:1 and 2:1 Host-Guest Stoichiometry: Molecular Docking and Density Functional Calculations

The complexation of β-cyclodextrin (β-CD) with cannabidiol (CBD) and Δ⁹-tetrahydrocannabinol (THC) was investigated using molecular docking and M062X/6-31G(d,p) calculations. The calculations suggested two possible complex formations of 1:1 and 2:1 host-guest molecular ratio of β-CD with CBD and THC. The preferred orientation of all complexes in this study exhibited the hydrogen bonding between hydroxy-substituted benzene ring of CBD and THC with the β-CD's secondary hydroxy groups at the wide rim. The calculated complexation energies indicate that formation of the 2:1 complexes (-83.53 to -135.36 kcal/mol) was more energetically favorable and chemically stable than the 1:1 complexes (-30.00 to -34.92 kcal/mol). However, the deformation energies of the host and the guest components in the 2:1 complexes (37.47-96.91 kcal/mol) are much higher than those in the 1:1 complexes (3.49-8.69 kcal/mol), which means the formation processes of the 2:1 complexes are more difficult due to the rigidity of the dimeric β-CDs. Therefore, the inclusion complexes of β-CD with CBD and THC are more likely to be in 1:1 host-guest ratio than in 2:1 molecular ratio. The results of this study supported the experimental results that the complexation constant of 1:1 β-CD/CBD (Ks = 300 M^-1) is greater than that of 2:1 β-CDs/CBD (Kss = 0.833 M^-1). Altogether, this study introduced the fitting parameters that could indicate the stability of the molecular fits in complex formation of each stoichiometry host-guest ratio, which are important for the assessment of the inclusion mechanisms as well as the relationships of reactants and products in chemical reactions.

Applications of Cannabis Sativa L. in Food and Its Therapeutic Potential: From a Prohibited Drug to a Nutritional Supplement

Hemp (Cannabis sativa L.) is a herbaceous anemophilous plant that belongs to the Cannabinaceae family. The cannabis seed (hemp) has long been utilized as a food source and is commercially important as an edible oil source. In this review, the positive and negative health effects of cannabis, the relationship between cannabis and various diseases, and the use of cannabis in various food products have been discussed. In addition, the scientific literature on the potential use of cannabis and its derivatives as a dietary supplement for the prevention and treatment of inflammatory and chronic degenerative diseases in animals and humans has been reviewed. Cannabis is being developed as a key ingredient in a variety of food items, including bakery, confectionery, beverages, dairy, fruits, vegetables, and meat. Hemp seeds are high in readily digestible proteins, lipids, polyunsaturated fatty acids (PUFA), insoluble fiber, carbs, and favorable omega-6 PUFA acid to omega-3 PUFA ratio and have high nutritional value. The antioxidants of cannabis, such as polyphenols, help with anxiety, oxidative stress, and the risk of chronic illnesses, including cancer, neurological disorders, digestive problems, and skin diseases. Cannabis has been shown to have negative health impacts on the respiratory system, driving, and psychomotor functions, and the reproductive system. Overall, the purpose of this research is to stimulate more in-depth research on cannabis's adaptation in various foods and for the treatment of chronic illnesses.

Application of a liquisolid technique to cannabis sativa extract compacts: Effect of liquid vehicles on the dissolution enhancement and stability of cannabinoids

This work describes the application of liquisolid technique to enhance cannabinoid dissolution from Cannabis sativa L. (CS) compacts. Effects of five vehicles, namely, volatile (ethanol) and nonvolatile (caprylocaproyl macrogolglycerides, polyethylene glycol 400, oleoyl macrogolglycerides and polysorbate 20) liquids, on tablet properties, dissolution and stability were investigated. The viscid oleoresin CS extract was mixed with vehicles before being transformed into free-flowing powder by the use of microcrystalline cellulose and colloidal silica as carrier and coating materials. Liquid vehicles had a nonsignificant effect on liquid load factor of CS extract. CS liquisolid compacts had acceptable tableting properties in terms of weight variation, friability, hardness, content uniformity and disintegration time. Different vehicles affected the hardness, disintegration, and wettability of CS compacts and thus the dissolution behaviors of cannabinoids to different extents. Dissolutions of cannabinoids from CS compacts were rate-limited by the disintegration process. Liquisolid formulations using nonvolatile liquids with low polarity or high hydrophilic-lipophilic balance yielded more than 90% cannabinoid dissolution. Stability studies revealed nonsignificant changes in tablet characteristics, cannabinoid content and dissolutions of CS compacts when stored at 5 ± 3 °C for 3 months. This work presents a general concept of how to successfully formulate CS extract with cannabinoid dissolution enhancement characteristics.

Cannabinoids-Characteristics and Potential for Use in Food Production

Scientific demonstrations of the beneficial effects of non-psychoactive cannabinoids on the human body have increased the interest in foods containing hemp components. This review systematizes the latest discoveries relating to the characteristics of cannabinoids from Cannabis sativa L. var. sativa, it also presents a characterization of the mentioned plant. In this review, we present data on the opportunities and limitations of cannabinoids in food production. This article systematizes the data on the legal aspects, mainly the limits of Δ9-THC in food, the most popular analytical techniques (LC-MS and GC-MS) applied to assay cannabinoids in finished products, and the available data on the stability of cannabinoids during heating, storage, and access to light and oxygen. This may constitute a major challenge to their common use in food processing, as well as the potential formation of undesirable degradation products. Hemp-containing foods have great potential to become commercially popular among functional foods, provided that our understanding of cannabinoid stability in different food matrices and cannabinoid interactions with particular food ingredients are expanded. There remains a need for more data on the effects of technological processes and storage on cannabinoid degradation.

Enhancing Efficacy, Performance, and Reliability of Cannabis Edibles: Insights from Lipid Bioavailability Studies

The legal sale of cannabis-enriched foods and beverages for medical or recreational purposes is increasing in many states and countries, especially in North America and Europe. These food-based cannabis delivery systems vary considerably in their compositions and structures, ranging from low-viscosity watery beverages to solid fatty chocolates. The rate and extent of release of the bioactive components in cannabis within the human gastrointestinal tract (GIT) affect their health and psychoactive effects. Studies with other types of hydrophobic bioactives, such as nutraceuticals and vitamins, have shown that food composition and structure have a major impact on their bioaccessibility, transformation, and absorption within the GIT, thereby influencing their bioavailability and bioactivity. This review outlines how insights on the bioavailability of other lipophilic bioactives can be used to facilitate the design of more efficacious and consistent cannabis-enriched products intended for oral consumption. In particular, the importance of food-matrix composition (such as fat type and level) and structural organization (such as fat domain dimensions) are discussed.
