Last night I was smoking a joint...the cherry (lit part) just got bigger and bigger, till it was about the size of the whole joint. The smoke was extremely hot and harsh. And sometimes when I light a joint the cherry will just crawl up one side of the joint...why does that happen? Did I light it wrong, roll it wrong, grind the weed up too much? Maybe it's because my stash is relatively dry right now... Incidentally I was disappointed and thought it hadn't worked too well and that I had wasted my weed, but...I got very, very high. Maybe it was that thick smoke.
