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.
