I don't think you can get high from secondhand unless you hotbox a geo and blaze like 2 or 3 blunts worth of chronic.
I'll consider myself corrected in that sense; but I still don't care for the smell of it.
Regardless, it's not likely to be an issue any time soon, so I won't worry about it for now.

I just wanted to post my 2 cents about pot being a gateway drug, as was stated earlier by some people. If anything is a gateway drug it is alchohol. Every single person I know who smokes weed or cigs started when they were drunk. PERIOD. If you enjoy getting really f*ed up you dont smoke weed to do it, you drink cause its way more effective. When drinking isn't enough any more then you switch to something harder.
