Brief summary

The primary purpose of this research is to identify genetic factors that may affect the efficacy and safety of medical marijuana, regardless of condition. The pharmacogenomics test detects DNA variants, which may affect the way drugs work and are metabolized in the body and/or detect potential side effects.

Detailed description

This observational, population-based study will examine genetic differences between ultra-rapid, intermediate and poor metabolizers of various formulations of Columbia Care's medical cannabis products in order to identify genetic factors that may affect the efficacy and safety of medical marijuana, regardless of condition. The goal of the research is to establish relationships between cannabis consumers, cannabinoids, and consumer outcomes. The study is expected to enroll 150 subjects across three cohorts, high daily dose users (poor metabolizers) that take more than 50 mg of cannabinoids daily (n=50), low daily dose users (ultra-rapid metabolizers) that take less than 10 mg of cannabinoids daily (n=50), and a control group (intermediate metabolizers) that represents the median daily dose user taking between 11-21 mg of cannabinoids daily (n=50). Columbia Care Inc. has identified trends amongst its medical cannabis users suggesting that there are some patients who are high daily dose users and others who are low daily dose users, with both groups assumed to have similar satisfaction with the products. The complexity of the endocannabinoid system combined with individual genetic predisposition and gene-environment interactions likely result in the variation in response seen with cannabinoid treatment.

Identification of genetic factorsDay 1Saliva-based DNA sample will be tested for known genes (e.g., the cytochrome P-450 superfamily)

Secondary

MeasureTime frameDescription
Satisfaction with therapy and adverse effects: surveyDay 1Survey tool will examine patient satisfaction with current dose as a covariate and evaluate adverse outcomes (e.g., mental health indications, reported unintended effects) based on varying doses and mode of exposure of cannabis within our analyses.
