i think that is bs because herion addicts could easily fly under the radar is they were scripted painkill-u's for their withdraws. how could they define whether or not you use at work or not. i personally medicate after work. as a patient of cannabis i think the only fair way to be fired from work would be getting caught medicating. if i were to be urine tested right now i would fail happily but the question would be if i medicated at work or at home.
