This article's kind of a mess.
I agree with the premise (the only success I've ever had consuming THC has been through legal edibles, where I can reliably control the dosage), and I agree - at least in part - with doing what it claims to be the solution (federal descheduling and regulation), but it does a poor job establishing any real connection between the two.
In particular it's not clear to me how federal regulation will make any of this work any better than regulation at the state level.
