Hey, I have the moon lazorrr that I used to take over the world to back me up here! I don't need an army!
We may not be able to control it, but we can certainly do more to reduce it. For example, drug checker police at schools, checking everyone every day for drugs, more drug sniffing dogs patrolling the streets, constant searches for drug producing facilities (i.e thermal camera equipped police helicopters are good at finding weed farms), prosecution for usage of drugs etc etc. I'm not saying drug problems can be completely eradicated, but a lot more can be done to reduce the amount of drug problems.
And I don't think the public are being lied to, the effects aren't really exaggerated as much as they should be, and it needs to be embedded into people from the earliest possible ages.
This sentence contradicts itself. First you say people aren't being lied to, then you say the effects are exaggerated and should be exaggerated even further. You do see the problem with your logic?
There's no point saying something is more harmful than it is. If the actual effects of heroin are not enough to scare someone away from using it, then they deserve to get [censored] up by it (of course the public should be fully educated about ACTUAL effects). You can't babysit the world.
1) Build a time machine, discover the secret of immortality, travel back to the middle ages with advanced tech
2) Declare myself god-emperor of man kind.
I read a book like this by Mark Twain, it was called A Connecticut Yankee in King Arthur's Court. Darn good comedy.
