My dad has always been honest about anything. He never hid any facts from me, but he did reserve them until I was old enough to be curious. For example, he never waited till I was 12 or 13 to give me "the talk," he just told me the facts when I was much younger and asked where babies come from. As a result, such things were never in any different perspective than anything else.

Ditto weed. My mom is very irrational about weed, though, and never liked the fact that my dad smokes. When he caught me smoking he only helped me hide it from my mom and made me promise not to do it in any circumstances where I would get caught (boxing the bathroom, at school, etc). He sees nothing wrong with it, and told me he'd rather I was spending $150 every week on an ounce of weed than less money every week at a bar.

I haven't told him that I've tripped or taken any other drugs because it's not something he'd want to hear. I will be open about it when I'm in college, and he'll see it as more acceptable for me to be dropping acid or something.
