You had more sense than I did. I was afraid of my dad too but I managed to hide it all fairly well plus parents of my generation barely had a clue anyhow and back then folk's medicine cabinets were full of goodies from paregoric to methaqualone to barbituates to amphetamines to serious little morphine pain killers that looked like sacharrin tablets. Then there was always very strong acid. Shrooms were legal. Pot was 13-15 bucks/oz. The only improvements for today's doper is higher quality pot (albeit costly), crack (we called it freebase), and cheaper purer heroin. All these benzodiazapines like Valium everyone crows about today were considered a trash drug in my day.
In any event, it's still a very dangerous world out there for kids who wish to try drugs beyond pot. I wish I knew the answer. Abstinence is obvious but few heed the call. BTW, I haven't used any drugs recreationally in 20 years. I always knew it would lose it's luster and it did. I think I was more the exception than the rule. Many in my age group now just anesthethize themselves with alcohol and pot or whatever their psychopharmacologist will dole out to a convincing story.
It's true what you say; and a lot of young teen/adults turn to drugs to escape their dismal reality (problems in the home, school, etc.) but in the end, drug/alcohol abuse is not the real answer. I don't know what is, but I know drugs aren't.
