@Figure8 it really is more likely that knowing the facts more often stops someone from doing the drug in the first place.
Terrifying unbelievable stories just don't work. That's been proven. However telling a teenagee that the pill they may take could be full of heroin would certainly put many of them off.
Same as telling them that after doing the first two lines of cocaine it stops working because your dopamine has done a huge dump and there's non left so it's basically a pointless 'high' to chase.
These facts actually work for prevention as well as keeping those safer for those that end up using a drug at a festival ect.
Saying 'people do coke then become crack heads and die in doorways' just doesn't cut it when a load of beautiful glittery young cool things are offering you 'a line'. It actually does the opposite as that person can not equate that narrative with the people they are seeing using (after all some of these people could be successful lawyers or doctors ect)
Much better the have the science, the facts. Then they really can say 'no thank you, that drug is terrible because it actually stops working really fast, does loads of damage to your mental health as you don't repaire the dopamine you loose for six months after. Not worth it for a line of powder thanks!'
Strengh , confidence and education is the most important thing for us to install into our children in all other subjects so why not in drugs, sex, alcohol.
