Parents may recall the nicknames for the low-potency pot of earlier eras: ditch weed, schwag, brick weed. THC potency, the chemical in marijuana responsible for most of its psychoactive effects, averaged just 3.7% THC in the early 1990s.
Now...average potency of flowers/buds in Colorado is 17.1% and marijuana industry websites boast strains can reach 30%. Furthermore, marijuana concentrates average 62.1% but potency rates of up to 95% have been recorded. 

The scientific research is clear that marijuana can permanently harm teens’ developing brains. These skyrocketing THC potencies raise the stakes considerably for Colorado youth.
