> Again, just look at opioid addiction for very clear evidence of the opposite effect.
I was playing devil's advocate, but agree there is more culpability to a seller if the drug overwhelms your ability to make the choice in the first place- however a lot of very illegal drugs do not do this. More so if you're using emotionally manipulative ads and selling methods as the alcohol and pharma industry do.
No doubt people were buying weed and hallucinogens on Silk Road, but there was A LOT of opioids, Xanax, cocaine, meth, and other highly addictive drugs that change people’s brain chemistry for the worse.
