Thanks very much, that's some good information there, I'm going to try and get hooked up with some before the Easter break, I'll try using the trick with the cardboard tube at dryer sheets. I'll probably smoke it outside though, I'd rather not risk it. How long do the visual effects of the high last? I'll have around 8 hours to myself, so.
Depends on quality and amount, I'd say around 3 hours for you after a few couple hits from the bong, 2 or 3. For some it takes 40 minutes, for some 4 hours but the effect is usually bigger when starting. I think it's around 1-1.5 hours for most people though and you won't get good weed I'm sure. I don't know how much you plan on taking, I'm assuming 0.5 - 1 gram spliff or bong. But I mean, you can be decently high and act normal. It's not like you're drunk.
