Storm Crow Reviewed by Storm Crow on . Urine Test Detection Time Hello, first of all I would like to say that SWIM isn't a frequent smoker. He was a frequent smoker up until December 17th. Since then, he has made 1 cup of cannabis tea and has smoked twice. He made the tea back in the middle of January, and smoked about 1/2 of a joint 1.5 weeks ago. Yesterday he smoked a joint, and today he smoked another joint. He weighs 152 lbs. and has a high metabolism because he eats and eats and eats and never gains any weight, even if he just lays around all the time. Rating: 5
