Hi Dear,

Understanding your concern. As per your query following discontinuation Tetrahydrocannabinol stay in your system for almost three months.
As urine test is done for its detection it can be detected up to one month after last exposure. Drink plenty of water to prevent early detection. It can also be detected by hair test as well as it will last for three months.

Hope your concern has been resolved.

Get Well Soon.
Best wishes,
Dr. Harry Maheshwari
