Body Detoxification, Cleansing, Health

So, Ive got my card, and Ive never been one to care where I smoked at, I just smoked. Im just curious if now that I have my card, where can I smoke and it be ok. I dont drive, so the DUI portion of things is not an issue. Im just curious where I can be and smoke still. The days that I dont have purely paperwork to do, I work in the field. During the time that Im working, Im gone from anywhere between 7-10 hours. In this time, I cant just go home and toke, then leave again. I have some jobs that are out of my city.
