Days 2 couple months
Depending on the use, frequency, and duration of use.
The heavier the use and the longer you using it, the longer it will be in your system. It is stored in the fat and in the hair which can be detected several months out..
If you are concerned about it, don't start it in the first place..It often gets you in trouble..Not a good habit to get into..
Stay well live_live...
