No.
72 hours max
you most likely will pass
Very minimal. A marijuana "high" lasts around two hours when smoked (and even less if you are a chronic user). Marijuana use about two-three hours before a shift at work should even be fine.
Max 3 hours. Stop worrying. I've smoked it since I was 15 and its done nothing but good things.
If you smoked a joint once, it will take a few hours and after that you will be fine.
Smoked hams are typically placed in a smokehouse to be cooked for several hours at a time. In some cases, smoked hams may be smoked for days. Unsmoked ham does not go through this process.
3 to 4 hours
Yes. It usually takes less 70 hours for your cheek cells to regenerate and get rid of the THC in your mouth.
I've smoked myself before, but only once, First things first, DO NOT DO IT.....Your system will feel it almost instantly as you hit the rock inside the metal, or glass pipe, But it won't take long, It's almost a Hyper feeling, but when it wares off you will need to lay down as i you just got a shot of sleeping dust, but other then that, If you smoke to much your heart CAN explode. If you smoke a lot in 2 hours, its possible you will be up for acouple days.
Drink a tall glass of urine 2 hours before swabbing
Nearly 50 - 70 hours.
No that would be stupid and really gross!
