Blood Drug Testing

How soon after smoking marijuana will it show in a urine test?

My brother smoked this morning (only 1 joint) and took a urine test that afternoon. Will marijuana show up in his urine that soon? It was his first piss since smoking.

1. Dont smoke its bad!!
2. he failed the drug test. it usally takes about a month or two for weed to get out of your system if ur a pretty big person. for me it only takes two weeks but thats because i drink lots of water and im very active. since it was his first piss then yes he most deff failed it. hope i helped!!(:
3. It shows eventually in your urine(4-5hrs) ,but if you're a fairly regular smoker then it shows every time you take a test.I know it is really irritating just get someone else's urine that's the only way out.
4. why in the world are you smoking weed? seriously just find a healthier thing to do.then you wont have to be looking behind ya and worrying about passing drug test.trust me my ex went through this and when he finally stopped smoking weed(and cigs/drinking too).even though it was hard at first.he got a better job, never worried about drug test, never worried when a cop pulled up behind him while driving and went back to school.just stop and give your body a healthy life style.
