that's seriously like asking 'how long is a piece of string'. there are so many different types of skunk and hash; if it's great stuff i'll still feel it about 3 hours after. some stuff's lasted a couple of hours, some has me rolling another within the hour. it all depends.
it really depends on whats in that blunt, theres so many different types man. if its middies, and its just you smoking, id give you about 2 hours
well, it also depends on what you count as "high", I'm really clueless and geeky for prob an hour or so depending on the type of bud, but after that i'm really chilled out for hours. So if you count all the lightheadedness/chill state of mind as being high, id say up to 5 hrs
first 45 minutes are the best..then it goes down steadily until the high is gone after 2 hours or so.
Depends on a lot: Quantity Quality Method of use Body wieght % body fat When did you eat last? ...etc. There is no clear cut answer unless you take these and many more factors into account. Just toke up, enjoy, and don't give a fuck about time!
Im going to smoke a Big fat sticky joint right now.... maybe 30 min full blown high... Ill be obliterated while smoking it.. I guess thats a hour..
If its some schwag...I wouldn't even make it half way through the blunt. I'd probably call someone who had a bowl of better shit I could get a hit of because I'd feel so shitty. Some mids...pretty chopped for an hour and a half or two hours. Maybe smoke another after the first one wears off if I'm not burnt as hell. Dank...completely blazed a really good body buzz and probably wouldn't be able to smoke a bowl until the cottonmouth went away and eventually would pass out after eating a large amount of food.
