Drug dealers are not only doing illegal things but they're not exactly humanists.
Some are humanists, I bet. And some are atheists, some are protestant, some are catholic, and some are Buddhists.

I suspect though, that you meant
humanitarians. I of course, never claimed that they were. What I did claim is that some dealers of pot (the only vice i named) practice good business ethics, trying to provide a good product at a fair price and not cheat their customers. Which makes sense if you realize that their business relies heavily on reputation and word of mouth.
I mean their business is pretty much based on people ingesting poisons, that will cause irremediable damage, make them age prematurely and die a lot sooner than they would have otherwise.
There's a lot of legal products you can also classify as 'poisons' (alcohol, caffeine, salt, and sugar, for example) that likewise affect our health in negative ways; Doesn't mean those purveyors of 'poison' can't practice good business ethics.
Forgive me for saying so but the idea that these people could have scruples of any kind is the apex of ridiculousness!!
As my rhetoric professor was fond of quipping, even though he acknowledged the irony of it: "Generalizations are generally wrong." I don't put the guy selling a few excess buds off his personal plants or the guy selling sticks on the beaches of Thailand to support his family in the same category as the drug cartels of Columbia or the vicious drug gangs of northern Mexico. Like most human activities, there is a spectrum here that requires nuance to fully understand.

And that is the last I'll say about what started out as a joke about Romulan ale. Just agree to disagree if you don't like my POV.
edit: fixed vicious for viscous, thanks
