I have smoked in the past. However, I haven't done anything in a while. Is been probably 2-3months (around that range).And, I wasn't a heavy smoker it was once in a blue that I did it. I'm wondering if I take a drug test whether it is a hair drug test, urine test, or a blood drug test can they detect marijuana in my system? I workout 3-5 times a week and I drink a lot of water daily. Can an one give me an opinion.Thank you. I have smoked in the past. However, I haven't done anything in a while.
