Yeah, I used to Marathon all the time, by that I mean that with a group of 5 people you each take a hit and try to hold it in until the joint/bong/whatever makes it your way again.

Then I realized that I didn't get that much more high out of holding the smoke in. Plus it can't be good for your lungs, as the bad shit in the weed has longer to be absorbed by your lungs. I think the cons outweigh the pros for holding your hits.

So now I just take my toke and enjoy it. It is true, there is a science to lighting the bowl just enough. With my nice wood pipe (that fits a gram), I can light it and pass it around and it will stay lit till it's done. Some of my friends don't know that and always light it when they get it... in the process wasting weed.

But, hey me and my friends have enough access to inexpensive (but not cheap quality) herb, but meh. It's too much of a hassle to tell them not to light it. I like to just enjoy the moment.
