From the bit of research i did preparing for my test; a higher BMI means more body fat. More body fat means more room for the THC to bind to ergo slower elimination.

Variables that enter into account are;
- weed quality and consumption rate
- metabolic rate of the person being tested (higher met. rate usually means skinnier people)
- exercise
backupz Reviewed by backupz on . Drug Test coming up! Hello All, I smoked on a regular basis but stopped in August. I tested clean on October 27th (home test). I then did some binge smoking (about 7 grams) over a two week period of time about 14 days ago. I am clean for 14 days now. By the time I am ready to take my drug test for pre-employment I will be 30 days clean. In addition, I am doing a full detox to my body also. Do you think I will be clean within 30 days to pass a lab test? Rating: 5
