Study Summary: In collaboration with Spark Medical Cannabis Clinic and PureSinse, a licensed producer of medicinal cannabis, the Britz-McKibbin research group at McMaster University is currently studying how the metabolism of cannabis differs in humans when ingested orally as an oil extract or vaped/smoked as a dried leaf.

This work is especially relevant for patients taking other medications concurrently, and who suffer from chronic pain, anxiety, or insomnia. Several factors impact patient treatment responses to prescribed medicinal cannabis, which remain poorly understood, and highly variable between subjects.

This study aims to better identify and characterize various metabolites of cannabis, known as cannabinoids, that are excreted in urine reflecting how quickly and in what manner the body eliminates medicinal cannabis.

Knowledge gained from this study will help us better understand how medicinal cannabis can be optimally prescribed to individual patients as a way to maximize its therapeutic benefits safely without any adverse drug interactions.

Investigating medical cannabis metabolism

Each person metabolizes cannabis differently depending on lifestyle, genes, mode if intake, and other factors that remain poorly understand. By studying small molecules found in your urine known as metabolites, we can better understand your individual metabolism. This information may help doctors better prescribe medicinal cannabis for optimized therapeutic benefits.


Participation in this study is voluntary. You are free to leave the study at any time ever after enrolment. Your decision will not affect the level of care you receive at SPARK.

Participants of this study will receive a $10 Starbucks gift card upon their second visit to SPARK clinic.
