Science Fiction-- particularly of the "New Wave" of The Sixties and The Seventies-- assumed that increasing liberalization of drugs would continue and that drugs currently banned would become not only legal but also as popular and commonplace as alcohol and tobacco are (or were, now that tobacco is becoming more stigmatized). Usually the drugs in question are "soft" drugs like marijuana and the hallucinogens (particularly LSD) rather than cocaine or heroin; often Fantastic Drugs are part of the mix as well. Some works decide to be ironic and legalize currently illegal drugs, but have alcohol and tobacco banned.
