Some settle for morels dipped in egg and cracker crumbs and saut ed in butter. Some prefer Twinkies, some nicotine or alcohol. Some like all the above. Some need antidepressants and sleeping pills and sedatives to cope in a modern rat race where serenity is no match for stress. All are legal, socially acceptable, and rightly so.
Some people prefer marijuana or peyote, coca or poppy derivatives.
All are illegal, though not for altogether logical, moral or philanthropic reasons. It has always been clear to me why government deems some drugs to be legal and others not. Especially Republican-controlled governments that preach personal responsibility and limited government interference in people's lives. But then hypocritically interfere in people's personal lives, religious lives and sex lives, apparently because regulating others gives them such a kick and a feeling of moral superiority. As a rule of thumb if a drug company has a patent on a drug and it gives significant quantities of money to politicians' re-election campaigns, then its drugs are legal and available.
