Based on some reading from Erowid.com, two days.
As long as it wants to stay.
Forever
24 hours
Depending on the THC toxicity of the weed, no more than 2 weeks.
Forever, say no!
it depends if you smoked it on the same day it will stay in your system upto 3 months but only be traceable for 1 month. :) weed<3
24 to 36 hours
It depends on the amount and frequency of smoking before the 14 weeks.
It usually takes 2 or 3 hits to get high. But, if you do get high.. it depends, it usually stays for about 30 minutes up to an hour. (:
