Well, I'm kind of undecided on the issue. At first I thought that the reason people said holding the hits in makes you higher, is really just because it makes you light headed, not actually higher. But then again, if you just inhale and exhale quickly, a shit load of smoke blows out, and shotguns get people high, and that's the same smoke you are exhaling into their mouths, so, it seems like a waste to blow it out.

Usually, I'll hold it in for 15 seconds if I'm watching a clock, just because I heard by that time all the THC you're going to get has already been absorbed.

Sometimes, if I'll take too huge of hit, I'll have to cough it out almost instantly.
