You like opioids, you do opioids, you end up addicted. You don't like opioids, you don't continue taking them after try.
You like stimulants, you do stimulants, you end up addicted. You don't like stimulants, you don't continue taking them after try.
It's that simple for me. By analysis of personality and genetics (that second is in theory as we know children inherit from parents but we didn't really break the DNA code) you can tell if someone is prone to drug use or not and if he/she is then what kind of drugs he/she is most probable to get addicted to. These are no ordinary chemicals. Also, don't start that "third eye" talk on me.

People do psychedelics because they reach satisfaction by this, different people get satisfaction by doing/experiencing different things.
So I'm against drug safety in schools like "listen kids, what I'm holding is a bag of heroin... some like it, some don't, heroin is highly addicting drug; now let me show you how to shoot up properly".
