How long does weed/pot/dro/m.j stay in your body?

[dancingmaniac3]

Seriously, I've been doing some research, and after smoking dro for the first time in my life today (about 6-7 hits from a pipe) i realized that i have a job that does random drug tests on people, including a urine test and a hair-snip test. Since this was my first time smoking marijuana/weed/pot ever, and only taking like 6 hits, probably doing like 3 of them effectively, how long would this weed stay in my blood/urine? I've been told that for constant pot smokers, as in 5+ times a week, it takes about 30 days to get it out of your system, varying on your metabolism and fat levels and crap like that.

What I need to know is how long this weed would stay inside my body, and how could i speed up the process. I heard drinking excessive amounts of water/pissing a lot could help speed up the cleansing process, but is that true? I've also heard about pickle juice...Lol, aperson could really help me with this, but i'm just wondering. Remember, this was my first time EVER of dro, and only about 6 hits from a pipe, and probably doing 3 of them right lol.

Btw, smoking weed wasn't all that great. Sure i was trippin out for a while, but eh, it went away after about 4 hours and i almost got caught at school twice. I had to tell my teachers i only got 1 hour of sleep and that i have bad allergies, making me seem tired and having red eyes. lol.

Thanks.
