I don't do any drugs, but I say legalize it.
Hell, legalize all drugs.
Sure, I don't necessarily like the thought of people being able to buy hard drugs, but it happens anyways, regardless of their legality, and I'd much rather that if people are buying these sorts of drugs, that it's coming from actual reputable companies, as opposed to cartels.
Your average corporation wouldn't be committing the typical atrocities associated with cartels, I don't think.
And as for the health issues with this, I say that if a person's willing to take the risks associated with hard drug use, let them face those consequences on their own. They're probably fully aware of their decision. I mean, yes, it's not good for people to be dying from the effects of hard drug use, but it is their decision to or not to take that path.
