Phyxius

So... I found myself caught in a DWI checkpoint after having smoked out my car. Yeah, oops. I didnt figure out it was a checkpoint until I couldnt get out of it though. They smelled it, had me pull into the parking lot, searched my car (he didnt give me a choice, but later he said I gave consent - bull), found my less than an oz and chillum. I called my mom (it's actually her car - I'll be 19 next week, I go to a university and am home for the summer) who came and got her car and me. She knows I smoke and doesnt care so that wasnt really a big deal. I got two citations - one for possession and one for paraphernalia. The officer said he believed I was driving under the influence but let me off for it. My record has been clean besides a speeding ticket last year. Now I have to go to court and probably do community service and/or probation and a fine. Oh yeah, all this is in New Mexico, btw.

Nothing too serious, I'm not too upset by it, I've never planned on getting a federal job anyway so I dont even care. I almost kind of even like having that on my record. I'm now officially one of the victims of the drug war.

That was Friday (the 13th), and I've stopped smoking, mostly just so I can tell the judge honestly I've been clean since. After a week I'm going to take a home drug test and see if I piss clean (I'm a heavy smoker) - I've heard of and know people that piss clean because their bodies are used to cleaning it out - I dont know, I'll be perusing this site for more info on that. So anyway, I'll play their game, piss clean for however long I have to. I dont mind quitting for a while. Just until they get off my back then I'll live my life like I used to. But I do have a few questions:

If I'm in a potsmoke filled room (not too dense, but, y'know, normal) everyday, will that have a significant effect on my piss?

What's the difference between pleading guilty and no contest?
