Question

this person asked me hypothetically i guess how long does it take for marijuana to get out of your system for a drug test. i said how would i know i dont use the stuff but maybe yahoo knows so anybody have an answer for this question

Answer 1

Typically marijuana can be detected in the urine for 1-3 days after a single use, but can last up to 30 days in rare instances. It is detectable in blood for up 2 days, and in hair for up to a year. Most drug tests look at urine, so that's generally the one you'd be interested in.
