Blood Drug Testing

How long to pass a urine or saliva test for hospital?

I am starting to work clinicals for college i havent smoked weed in 3 to 4 months. i drink on the weekends. how long should it take for my urine to be clean? and saliva too? also how far back are hospital tests able to detect drugs/alcohol?

1. It would take about a month for pot to not show up in urine. Less for saliva. Alcohol is legal, so they will likely not test for it. Just don't let the booze interfere with your work and it probably wont ever be a problem.
2. generally about two weeks.. what I usually do is wear all my warm clothes and go for a long bike ride or run.. the more you sweat the faster it will go out of your system... :)
