Blunts are only wasteful if you have 15 bucks to get you stoned for the whole day. otherwise, be a boss, go around town smoking blunts all day, i mean thats what we do around here when we are bored. and as far as the time it takes them to burn, i dont know if you guys talk about the days current events while you smoke , but if im smoking a 1 gram blunt it takes about 8 minutes to smoke it and thats hitting it ,hold 10 seconds, blow out, wait about 15 more seconds,reapeat til done with maybe 1 30 second break to catch my breath. Sorry if that makes no sense at all.
