I haven't smoked in almost 2 years. I got annihilated the other night and my friends got me to smoke, and I goto MEPS this wknd to swear into the Marines. I have a drug test for them on the 2nd day, Saturday. Will I be fine if I just drink about a gallon of water per day or should I get the detox drink, The Liquid Stuff? I also heard they test for detox drinks now??
