Not nessecary. Do you have a knife, (what male doesn't?) Smoke as much as you need to get high, and put it out. Next day, scrape out the ash w/ your knife, and cut down to the fresh green. Toke up some more. Have fun dude.
Me and 1 buddy smoked it starting at 3 a.m. yesterday and it burnt till about 4:50 a.m. It was intense. Sorry about the big pictures.
