how much marijauna can be smoked before it shows up on a drug screen (piss test)?

Answer 1

Any amount will show up. But don't listen to these responses, it only takes about a week before it leaves your system and if all you did was just a joint or two, it should be undetectable in about 4 days.

Answer 2

so this is what happened to me, I applied for a job as a lifty (chair lift operator) at a ski resort outside of seattle when I was going to school, I was **** for the job, wildreness first responder experience on mountains etc. the guy really wanted to hire me, the resort however was just bought out by a big conglomerate and implimented a drug test, well anyone that knows anything knows that lifty's smoke a lot of pot, so they lost 70% or their preveious employees and I told the guy "I don't smoke that much weed, but my home mountain opened last week and I smoked with friends" (quite a bit several days worth) he told me come back in a week and take the test you will be fine, so I was all over the internet looking into these various cleansing products then I came across norml's home page (I don't remember the acronym but something about hte nat org for marajuana leaglization) the endorsed nothing but simply said drink copious amounts of water and when you go piss take vitamin b12 so your urin is not so diluted, so for a week I drank water and cranberry juice and coffe (diaretics flush more fluid through your system) and niacin tablets which speed up you metabolizm burning fat which is where the thc resides, then the day of the test I drank about a gallon of cranberry juice 2 redbulls a couple of raw beets some niacin and some b12 (oh yeah Ib profin does something I don't remember what thought) the testing facility was about a half an hour away and I peed three times but I passed, no questions asked, the other tip is to not start you pee stream or finish off in the pee cup as initially there is residue in your blader and the end of the stream carries residue, this should help
cheers

Answer 3

Any amount will show on piss test and ussually for 30 days. What's trippy is that coke & meth only last about 3-7 days (longer in blood for all drugs)

Answer 4

It does not take much. Even exposure to the smoke of someone ELSE's joint will show up as a positive screening.

Of course, almost EVERYONE who gets a positive will tell you that it was somone else's smoke, not his.

Either that, or the specimine bottles were dirty.

Answer 5

regardless of how much you smoke, pot stays in your system for at LEAST 30 days. for a piss test, but if they do a hair analysis your screwd , it will show up for the rest of your life

good luck

p.s. and drinking special mixtures doesnt work either so save your money
