Yeah, this is not the best question because you'll get very different answers from different parts of the world, or even different parts of the US.

I graduated more than a decade ago, and there was a lot more nuance than what you described. They taught us about different types of drugs and what their real effects were. I remember learning in high school that marijuana is less dangerous than cigarettes and alcohol.

In elementary school for me, there were big anti-smoking campaigns, but nothing about alcohol or harder drugs. The "just say no" was about peer pressure and doing anything you felt uncomfortable doing (including inappropriate touching).

With fentanyl specifically, that's not too far off lol

That being said, drugs are great m'kay
