I have read numerous places that a single use is only in you system for 1-7 days and moderate use 1-3 weeks. I was wondering if it would be considered a single use if I smoke 3 or 4 grams in one day. I am clean now and want to know if it would be in my system for more than 2 weeks if I smoked that much. I am 135 lbs. and have a fast metabolism, I am not fat. Please let me know what you think.
