dude, weed will be the least of your worries....
im x-82nd airborne, i never knew most of the drugs existed until i met people in the army.. Ketamine, xtasy, cocaine, and lots of pot..... they did random testing, get tested hot once, they have to rehabilitate you 1st before charging you, so some AA meetings if you get caught once. coke was a fav for most cause it was in and out of your system, K wasnt tested, and mdma wasnt until i got out.
no shit i sat im my barracks and smoked hella weed, we used our GAS MASKS to blow into and clean the smell away in the charcoal filter...lol common, my b day is 4-20
