Ep. 32 - THC Dose: How High Is Too High?

Cannabis Nurse Truths

In 2020, an estimated 209 million people around the world, or just less than four per cent of the global population, reported using cannabis in the past 12 months. Around the world, cannabis is being legalized or decriminalized and hundreds of thousands of patients are currently being treated with medicinal cannabis. Cannabis products are becoming increasingly diverse, and vary considerably in their concentrations of the one psychoactive cannabinoid found in cannabis, delta 9 tetrahydrocannabinol, also known as THC. It is in use of THC that we develop risks and harms from cannabis.

Currently, there is no standardized THC dose or measure that has been recommended by experts, and there are no approved treatments for THC intoxication. On this episode of Cannabis Nurse Truths, we review the concerns with standard THC dosing - just how high is too high?
