Typical marijuana detection times are 3-30 days depending on height, weight, and smoking habits. We've seen people go as high as 100 days, so its hard to say unless you test yourself. Your probably going to need at least 30 days to get clean. If you don't want to stop smoking you can use Quick Fix, a synthetic urine that is 100% effective if you get the temperature right. Most pre-employment drug screens will not watch so subbing would be your best bet. If you decide you want to quit then read the Dilution sticky at the top of the forum. With the proper diet and exercise you can get clean naturally if you have the time. Most don't have the will power to abstain so thats why we all recommend QF. There is some great info here so i suggest you start reading up. :thumbsup:
