How long does TCH show in a blood test?

Answer by  Snook (69)

It depends on how much you smoke. But the time maxes out at around 45 days. One smoking session for someone with a clean system takes about 3-4 days to be clean. Smoke 2 days later and then have to wait about a week; it doubles every time you smoke.

TCH is stored in fatty tissue and in the brain, so it can show up for quite some time in a blood test. Blood tests will show TCH much longer than with a urine sample. You can have TCH present in your blood for upwards of one month after usage.
