Have you ever drank alcohol? Smoked pot?
Since then, I have had a successful career in business & am retired. Drugs are out now - too old - but I like to have a drink occasionally. So, I'd say I have some first hand knowledge. If you bother to read my comment history, you will see I am a sane conservative.
Responsible drug use is the same as responsible alcohol use - moderation & infrequency. Children should never use drugs, any more than they should vote - their brains are not yet formed & they lack maturity. While I agree that some drugs are too “intense”, & therefore dangerous, the government will never keep people from getting a buzz by one manner or another. Ironically, the drug war has spawned the designer drugs, as they are easy to make & transport compared to pot or coke, which are bulky & smelly.
People have to learn for themselves what is good, & what is bad for THEM. Some people abuse alcohol, some don't. Same with drugs, food, sex, & money. It should be clear to anyone that has ever been in a bar that people like to get high - some, real high. This is not gonna change until the eugenicists take over, & perhaps not even then.
