my advice is similar to others:
don't smoke too much. It's a weird high and newbies often have trouble even realizing they're high, because its way chiller than they expected. It takes a while to really kick in, and the high builds over 30 mins or so (for me), and so keep it low and have a good time.
For the question about smelling like pot, I suggest staying far away from that type of mindset. I've never been caught, and its been like 8 years, because I don't worry about that shit. Most times people high end up getting "caught" because they are worrying about acting funny, and as a result, end up acting even weirder.
Take a good bottle of eye drops with you, and forget about any worries. Just have fun acting like a child again~
I disagree. Actually I think it goes from 1-2 minutes to get to full blast after you finish smoking the proper amount, then it decreases from there.
30 minutes? You're talking like half the duration of ecstasy build, bro. lol.
