A clinical chemistry study measured the Tetrahydrocannabinol (THC), 11-nor-9-carboxy-THC (THCCOOH), and cannabinol (CBN) levels of marijuana users within hours of use. The heavy users were tested 4 times a week, occasional users were tested 2 times a week. They were tested with breath strips before and after smoking a joint with 6.8% THC.
THC had the most cannabinoids in their breath. While THCCOOH, the chemical that stays in your body, was non existent. CBN was only contained in one test. CBN is used in oils to help seizures, and it saves lives.
All the breath samples were positive for THC for heavy users about an hour after smoking the 6.8% joint. The THC levels went down about 25% every hour. Only one heavy users tested positive after 4 hours.
90.9% of the occasional users tested positive for THC about an hour after smoking a 6.8% joint. The THC level went down 30% after an hour. One user did not test positive for any THC.
These strips look to be the future of testing for drivers driving high. They have to update the THC percentage in their joints for the next study. That will change the time THC stays in your system. Or you can move to Michigan where medical marijuana users can drive after consuming marijuana without breaking the law. Remember, they can’t test edibles on your breath!
