Drugs were always a no-no. There were other family members that did do drugs but we were always told to not do them because they were bad. So we did not talk about them because we were expected to just not do them.
I would not say this is when boys become men. I would say none of these are bad ideas. I would also say, if this is really what you think separates men from boys, you need to learn what separates girls from women.
