Yeah the addiction is to dopamine, cocaine is just an easy way to get that fix. Gambling and other lesser addictions give the same dopamine fix, but then there are good addictions that provide the same dopamine hit. None of them are as immediate and as powerful as the old nose candy though (aside from amphetamines).

Some people are hardwired to “love dopamine” more than others (so called “addictive personalities”), so it’s all about replacing a bad addiction with a good one. I have ADHD and it went untreated for nearly 4 decades, I was always the one out of my group of friends that could be like “nah, I’ve had enough coke tonight, my sinuses are on fire and I’m not getting anything more out of it, I’m just wasting money at this point” meanwhile my friends are always like “YOU WANNA DO/GET MORE?!?” 😳 I still get high from it, but I can apparently control myself a lot better than other people.
