Agreed. Anecdotally, my buddy's wife had a really bad experience, because her weed was laced with something. This is the main reason I would love to see some regulation of drug trade ( edit: some clarification may needed; legalize and then ensure it is clean and it is what it says on the container ).

Not that it is panacea. Anecdotally, IL has legalized weed and edibles are extremely inconsistent in terms of what they contain ( it says it should x, but it can easily be 2x or .05x -- it is infuriating given really high tax on those ).

Still, I believe it is a step forward.
