How Long Does The Drug Stay Ins System After Stoppage Of Smoking Weed?

I have gone 48 days without smoking weed. I use to be a causal smoker maybe smoke 3 or 4 days out of the week and it was usually a gram or .5 with like 2 friends or 1. I have been clean although I ve been around it sometimes but always in a ventilated area. I m 5,5 skinny and weight about 130 pounds. Im very active I play a lot of soccer at least 3 times out of the week. You think I will be clean?
