The Iron Liver equipment trait in the Adventurer's Armory is the only place I can think of where poisons and drugs are mentioned separately. Whether or not that was an oversight or deliberate I don't know. In game, I'd treat them separately. Drugs have an additional mechanical feature in addiction that poisons lack. Using the argument that most if not all recreational drugs are poisonous fails to account for the first lesson I learned in my medicininal plants class: that everything is a poison, and that the only difference between a medicine and a poison is dosage.
Alcohol is a poison, that is literally what it is. The only reason alcohol is mentioned separately under the "Iron Liver" trait is because you only get a +2 to generic poisons/drugs, whereas you get a greater bonus of +4 to alcohol specifically, it being a subset of all poisons. They are most certainly not two separate things.
