IMO if someone is selling a drug that is either mislabeled or cut with something else, that's an issue. However, if someone is selling a clean compound that is labeled appropriately, to someone who wishes to buy said compound, how is that an issue?

A person's rights are not being violated when they buy a compound that they are fully aware can cause harm. Do you think there is anyone out there buying a bag of heroin who can straight up honest to god say "oh, I had no idea this was addictive or could cause me harm"? I feel like what you're saying is actually more relevant to doctors than to street "drug dealers", as when a doctor prescribes certain things like benzos for example, they often don't inform the patient of the dangers. And when a doctor prescribes something, it's coming from a position of authority so there isn't the same assumption that it's likely unsafe, that you'd get when purchasing something off the street.

I personally feel ALL drugs should be legal, and it should be up to the individual to decide what they do or don't want to put into their body. I feel like it'd be nice if those selling would include some form of informational booklet or whatever that informs their client of what they're taking, along with potential dangers. But I still feel like it's up to the individual taking said compound to properly inform themself of the potential dangers, and take the appropriate precautions.

TLDR: It's not my dealer's fault if I get addicted to meth or something, it's MY fault for buying said compound and taking it.
