Being so out of touch with your kid is one of the main ways to create attention seeking behaviour. Not the only way, of course, but it’s still generally a bad idea to have no relationship with your kids.

My parents knew exactly what we were up to, and in most cases, our first time experimenting with anything like that was supervised by our parents. They wanted to make sure we knew what we were getting into and how to be safe despite taking risks like that. They didn’t really have to worry about me, I’m Autistic and have no interest in drinking or smoking anything, but my older brother and the older of my younger sisters very much partook in any of the safer recreational substances. One advantage of talking with your kids about this stuff is that when you warn them which ones are actually the problem, they have no reason not to trust your advice. There are some “not even once” drugs. There are some “you gotta try it once” drugs, and there are some “it’s not a good way to spend your money, but otherwise fun” drugs.

Me personally, drug of choice is videogames. Way cheaper high. Though it can be habit forming, make sure it never feels like a priority over doing real-life stuff.
