Pharmaceuticals are not a question of taste like alcohol and food, they're strictly a matter of purity, stability and toxicity, which is clearly better supported by being produced by an industrialized country with sometimes hundreds of career chemical engineers running the show in a billion-dollar company with processes etc., & who have liability for lawsuits worth hundreds of millions of dollars if they put anything remotely close to the shit recreational drugs are cut with, like horse tranqualizer and deworming agents and whatnot.
The best elites can dream of is pharmaceutical levels, but even the most pure illegal stuff comes from a production line that's isolated from the rule of law and from transparency and liability and also likely from actual professionals, so it's likely still more toxic than it needs to.
The real "advantage" of cocaine is mostly that the molecule has an inherently stronger euphoric effect, I would assume (I've never taken it), also making it a worse therapeutic if you want to actually do a better job vs just feel "high".
