It's just way too amazing.
I find it doesn't hit me till about 10 minutes in, i usually get back from work, hit a bong and do some housework while it picks up (listening to music of course) then i start exercising.
Exercising when your baked is amazing, i love it :-D

I love it when you hit a bong/pipe/what ever and nothing happens for about 20 minutes and you think ahh turd nothings happeneing, then woooosh.
