Narcotic may be whatever you want, but the debate has to be honest and transparent, not shady and criminal: if you want to legalize heroin, make a case to the people, get it approved with safeguards, say like Portugal or France to some extent (Methadone), and make sure it won't profit people who also do other things with the proceeds of sales.
The problem with Narcotic is simple: people lose freedom when getting into addiction, then with hard narcotics they also lose the ability to make important life choices, minors and generally disfavored people are targeted by addictive substance sales people, production is rarely done well (because most fields should be used for food, if they are used for more profitable narcotic purpose legally or due to lax enforcement, ALL FIELDS become opium fields like in Afghanistan, which can cause food safety issues etc.
You can't just talk as if narcotic consumers are innocent party goers. Many are absolute victims and we must talk about it without crypto entering the debate. Crypto is just a weak way to try to hide the source of completely illegal funding for narcotics without going through the painful discussion with the population that we may have to sacrifice a lot of victims for the sake of spending less on narcotic enforcement.
