I find discussions like these fascinating where you see collisions on people's thoughts about different drugs.
How many of you get to deal with people on the downside of casual turned problem coke / heroin etc use?
People are more familiar and wary with the life destroying effects of big time opiates like heroin/fentanyl, which they fully deserve.
Coke has more truly casual users then opiates. No question. But coke really wrecks a lot of lives too. Usually faster that an opiate addiction. Lots more successful people derailed by too much blow than shooting H.
To echo what Bonk said, with a majority of coke users, they will generally keep using until they run out of supply or money to buy more (think classic coke bender)
This is the same behaviour that manifests with any serious addiction, but due to the shorter life of the effects, users consume a lot more and spend a lot more $$.
Again, coke has always been viewed as a lifestyle, rich person's party drug, that doesn't normally come with the "eww" factor of people sitting around with drug rigs sticking out of them.
Pot is not even comparable to those classes of drugs, and I think society has rightfully finally figured that out.
