We won’t talk about crack, of course
It's rare to see 70-80 year olds with a casual cocaine habit, and of the people I've known who have been interested in cocaine - the consequences caught up to them by the time they turned 30 with a consequence peak in their mid-20s.
I've seen the use of "party drugs" lessen or cease as people I know get older. It gets harder to fit those drugs into your life when you have increased responsibilities and fewer opportunities. Opioids are not party drugs for the most part. Alcohol is obviously a party drug, but like opioids it can become an acute addiction and a maintenance issue (even more so than opioids due to the uniquely dangerous withdrawal symptoms). A drug like cocaine is, to me, similar to molly/ecstasy. It's not fun to do maintenance amounts or to do a lot solo. So use seems to wax/wane with lifestyle. A pattern I have seen a lot is people who used/abused cocaine and alcohol frequently when partying, eventually stopped with the cocaine, and continued on as alcoholics into their 30s/40s/50s.
One interesting things about cocaine addiction is it has one of the strongest genetic/hereditary links of any addiction...
