I'm sure this has been discussed, but I couldn't find a guaranteed answer (assuming there is one).

I'm 27, and I've been smoking on and off for about 10 years. I'm considering enlisting in the U.S. Army, and they obviously drug test. The urine test I'm not too concerned about, rather the blood test they administer. My question is, how long does marijuana (THC) stay in the blood? Is it dependent on one's weight and metabolism? If so, I'm 140 lbs. and my metabolism is pretty fast.

Thanks in advance.
