How long does weed stay in the blood stream?
It depends on how much weed you smoke and your metabolism. If you smoke it occasionally it will remain in your system for up to 10 days. If you smoke marijuana on a regular basis it will stay in your system for as long as 45 days, and if you smoke marijuana at a constant pace, it can stay in the body for 90 days. Marijuana is fat soluble. It stores in the fat cells of the body, the brain, the liver, the kidneys, in other words the major organs.

Reply:Marijuana can be detected in blood samples for around few days to a month depending on how often you smoke it.
Reply:Yeah it lasts around 2 weeks - 1 month unless you use alternative methods, like chewing on charcol. Gross, but effective. I dont think they check for drugs unless they're screening you for a drug test, by the way.
Reply:Cannabinoid byproducts are stored in fat for up to a month. But since your useage is so small, it's unlikely to be detected for that length of time. In addition, the doctor won't be checking your blood for marijuana use. Drug screens are not routinely done.
