I am interested in the devil's advocate to current trend of Marijuana legalisation. _EVERY_ discourse on the internet (besides religious cranks it seems) tends to favour legalisation. If something is too good to be true, then it is.
There could be a significant population who are risk of adverse outcomes, especially 18-24 users whose brains are still developing.
What I’ve noticed: there are lot of incredibly smart and resourceful nerds who could be doing amazing things in the world but instead are pumping currupto all over the internet.
