Study participants were made to undergo 15-minute exposures each week to low THC, which consisted of 0.5% weed smoke, for more than a month. The smoke itself was delivered using a pump inside a vehicle. Meanwhile, after a one month washout period when they abstained from exposure, the participants were then asked to repeat the exposure in the same conditions but with high THC cannabis smoke this time. The researchers collected urine and hair samples after.
