Ok,from what I know,if you smoke one time,it's 3days till you're clean,so if you smoke,then wait one day and smoke again,it will be 5days,on do on,and so on....until you reach 45 days.and then after 10 days your thc will cut in half,and then another 10 days it will cut in half again.if you don't smoke.drinking water and exersicing does absouloutly nothing.trust me.but I think you are good,go get a home test kit and find out for yourself.
