Yarr that brown stuff be the tar from the weed. Its actually safer (though I don't do it) to only smoke half a joint and put the rest in a bowl or whatever. The hotter the smoke is, the more active chemicals in the smoke are. Certain chemicals in the tar will be less harmful or even inactive if the smoke is less hot. Giving it a chance to cool down by putting it in a decent bowl is good for your lungs arrr [/weed pirate]
