Difference between THC Blood vs Urine THC Drug Test

The difference between THC Blood vs Urine THC Drug Test is in cost. Testing THC in blood test will only tells you about THC that’s recently consumed, and is incapable of revealing consistent use. Urine testing, however, is far more likely to tell you if a person has consumed cannabis.

In all seriousness, blood testing has some major downfalls. It’s costly, it only tells you about THC that’s been recently consumed, and is incapable of revealing consistent use. Urine testing, however, is far more likely to tell you if a person has consumed cannabis.

After you inhale some smoke or vapor, THC course through the blood streams and works it’s way into fat cells. This is why cannabis is notorious for taking an unbelievably long amount of time to get out of your system.

THC is re-released into your body as you burn through fat cells. For occasional users, the half-life of THC is thought to be around 1.3 days. For heavy users, the half-life can last as long as 5 to 13 days. In the medical world, “half-life” is the time it takes the body to get rid of half of a dose of medication.

Urine testing looks for the presence of THC metabolites rather than THC itself. While a blood test can detect cannabis use for a maximum of about 7 days after consuming, your urine may test positive for THC for as long as 100 days. It really depends on how much you consume and how often.

If you only use the herb every once in a while, chances are it will be out of your blood within one full day and urine within one to two weeks. Heavy users can expect THC or THC metabolites to hang around for much longer.
