If you smoke one joint how long are you high for?

"It depends on what the joint has in it. Maybe you were ripped off and I am high typing this wow chinaman. Anyway asians, it also depends on if u are used to weed. If you are, it may be about 1-2 hours. It also depends if u will be splitting it. Anyway, if ur not used to it, you will have the ride of your life." That was the last answer. Its so wrong, I left it there so you could see what I'm talking about. If you smoke regularly, you'll be high for maybe 15-20 minutes. If you've never smoked, 45 minutes, tops. "Edit: Depends on what kind of marijuana you get. More potent, the higher you will get. You will be high for 1-2 hours, 3 hours top if you are not a regular marijuana user. Also depends on height, weight and tolerance level etc. But a good joint by yourself will get you high for 1-2 hours, coming down for another hour. Happy highs! Be responsible.
