Not really, heroin has been laced with fentanyl analogs and even things it doesn’t synergize like in cocaine causing random deaths by knowingly selling (pre)cut chemicals isn’t morally neutral.
What I actually think: Unfortunately if the casino and alcohol industries make 90% of their money from addicts I’m afraid the hard narcotics industry is even worse still. Traffic good drugs only if you have strong pro-social morals and want to sleep easy.
It’s hard to see it as a moral matter, like all business it’s just sales. Knowing purity doesn’t prevent the OxyContin issues these are just dangerous drugs that are addictive to a lot of people and there is a non zero chance it’ll kill someone. Psychedelics can trigger schizophrenia and mushrooms are unpredictable, but the assumption is that it’ll give people insight. Alcohol is the most used date rape drug, so legalization and standardization isn’t even a solution except for its safety in the case of methanol.
Technology is known to be highly addictive as well.
