At the end I don't care what chemicals do get mixed but trips from THC substitutes are not the same and not only for me subpar to the point of ignoring it (closer to being dizzy from alcohol than fun creative weed, also tolerance seems to be built much faster).
another issue the article doesn't mention is the thca loophole.
the farm bill only concerns itself with straight delta-9 thc, and as it turns out most weed has very little delta-9.
most weed is high in thca and fairly low in delta-9 thc. the thc-a is converted to delta-9 thc through decarboxylation by heat -- when you smoke, vape, or cook the flower, the thc-a become delta-9 thc.
because of this, i can visit a hemp shop here in indiana where i buy what seems to just be plain old weed of pretty decent quality. it's labeled as thc-a and costs about $250/oz.
