how you gonna say don't know the dangers when i personally experienced and saw the dangers first hand? you have no idea what you're talking about. you can't reach the tenders of drug abuse to combat it. you have to get deeper.
the lack of teaching the dangers of drug addiction isn't the problem, the root of it is people use drugs habitually as an escape and to self medicate for deeper issues going on. teach healthy alternatives, be a role model etc
i struggled with depression and feelings of loneliness since i was practically in kindergarden. i always felt different and not like the other kids, like no one liked me. and as a child growing up i experienced and saw those closest to me dealing with their issues by coping through drug and alcohol abuse so naturally as i got older and those feelings became intensified i went down the route of drug abuse because i was indirectly taught it through my environment and surroundings, that's why they say it runs in the family because it's a learned coping skill. you focus on that, you teach healthy and productive ways to deal with ones feelings, not the dangers
if teaching the dangers of addiction works then most people would not smoke cigarettes, eat unhealthy food habitually etc.
