THC stays in your system for a maximum of 30 days,
depending on how much you’ve taken.

It can be traced through your urine.

Answer by offroadjunkie
to the best of my rememberance from college anatomy and physiology it is:
saliva swab test= 21-24 days
blood draw and thc assay (blood test)= 31-34 days
urine test= 27-30 days

this is assuming you have a normal metabolism and are not diabetic. if you have a fast metabolism and intake large quantities of water you can reduce these positive times by 10%, but if you are diabetic then you can increase these times by 15-18%, if memory serves me right.
