First I wrote something similar, now I see this. Fully agreed!

I mean, if he's testing his stuff and isn't misrepresenting what he's selling, is it really wrong to sell heroin or cocaine?

Same.

I was going to add something in these lines, but even if he was heroin dealer but did it responsibly with testing the drugs and making sure he doesn't scame anyone it's still a lot better than some guu who replaces his job and sell heroin laced with fentanyl. it's way too complicated for me to be able to just judge them by the drug they sell. because you can never get rid of every dealer and someoke is just going to get their customers. the best you can do is damage control because the damage is going to happens anyway

edit: based on the downvotes people want fentanyl and other even more dangerous shit to the streets than heroin is I guess :D (just kidding I know these downvotes are not from people wanting heroin users to die but from people who think heroin is too big of taboo to be spoken like this. I would have no one down voting me if I was talking about laced weed and how it's better to sell unlaced weed)

I am not saying it's okay to sell heroin. I am simply stating that it's a lesser evil to sell pure and tested dangerous drug than selling untested and even more dangerous drug
