Say you are 14 and you must take a urine test 8 days after smoking...

...marijuana for the first rime? Would you test positive for marijuana? It is a person weighing 120 lb.
Actualy marijuana stays in your blood stream for only 72 hours. A first time adult user with average body mass will have marijuana in their urine for 10-14 days. I was hoping the time frame would shorten for someone who is 14 but it appears not.

"say" and "it is a person" .....I think we're talking about you Scott, admitting it is the first step to recovery!

You will turn out positive...But don't give up faith. Drink a lot of fluid, specially water. So you will piss more often. I know how you fell believe me , so hope this helps. Wish you luck !

Sweetie wherever you heard it only stays in your blood stream for 72 hours was complete BS. It varies from person to person depending on different factors from size, amount person smokes ETC. It can be a few weeks to a few months. If you ask on here though you will get people saying from 72 hours to years... People really don't know on here
