Parents get high

My dad first got me high when I was 12, and I started on my own when 15. Mom smoked a bong pack with me once, tried telling me about the old days when she smoked just as much as me, then passed out upstairs, haha. My dad still smokes with me and my younger brother, and we've had so many good times getting high and bullshitting. Thats the only thing all three of us have in common.

If my son makes the decision to smoke, I'll be there to smoke with him. So long as he's 16 and aware of what's around him and not a zombie.

 

Both my parents smoke, and not just occasionally, multiple times everyday. The thing is though, that they don't know that I know they smoke. I think they think that because they have been very careful while I was growing up, that I don't really know what marijuana is, what it smells like etc. But I do, I've smoked myself, and I've known they do for quite some time.

I don't really know what to do, do I just go up to them and tell them I know they smoke, and that I'm cool with it, or wait for them to approach me? But, I'm 16, and wondering if they ever will tell me. I don't want to make things awkward.
