Just came here to say alcohol is a drug too. Saying “alcohol and drugs” makes it seem more harmless despite it being one of (if not the) most harmful drugs we know of. I know its a common way to phrase it, not judging, just leaving my 2 cents.

Also to answer your question, I had my first drink at 14 and my first cannabis joint at around 17. I still smoke weed but almost never drink.
