Actually, if you're talking about "wasting" weed, if there is such a thing, I'd have to say that joints consume a bit more weed than a bowl or hitter.

For me at least, pipes are about convenience. I don't want to have to sit there and roll one up if someone wants to smoke, so with a pipe, I just whip it out and we're ready to roll. And I get torched from bowls, bubblin' or not, and hitters as well, so it doesn't matter to me as long as it gets the job done.

When we do roll joints, it's usually a few fatties for a special event, like a concert or something. Makes the moment that much better. ~

And as for wake-n-bake's, I don't do them too often anymore unless I know I'm wide awake, otherwise as soon as I get high, I fall back asleep.
