Don’t listen to the ones that are trying to scare you they only test for weed or crack or prescription drugs at the end of the day if you want to smoke some weed do it the day you land and don’t do it again you’ll test negative by the time your home weed for first timers or someone who hasn’t smoked within 30-60 days will have weed out of there system if they smoked only once within a week. Like I said buy a vape smoke the shit out if it drink get drunk cuz they’ll only text for weed , crack , coke, Heroin and Prescription drugs, meaning zanax , Opioids , etc but nicotine and alcohol they don’t give a fuck bro. On god I wish someone told me this when I was on holiday leave . Don’t get a DUI and don’t get arrested, don’t do anything they will test you for. Nic and alcohol are safe to do !! Coming from a soldier who just hit out of basic in 2021. YOU ARE FINE. Enjoy enjoy the time you have with your love ones ☺️ good luck my boy and take some pics with you and a Apple Watch you’ll thank me when your done with ait .
