If someone were to take one hit of high grade cannabis how long would that hit show up on a 4ng drug test? This person is hypothetically 185 lbs 5'8 with a decent metabolism.

THC detection is very dependent on history of use. What type of test is it. Not familiar with 4 ng cutoff for any?

One hit would be eliminated within a day or two in infrequent user, whereas THC has been detected for extended periods (30 days +) in chronic daily users.

Thank for the rapid response. I have been clean for two months, and it is a urinalysis. The four ng cut off might just be fear mongering by over zealous testers.

So if I were totally clean when I burned I should be clean within a few days?

Once again it is the history of use. Use sufficient to create a build up in tissue.

What is four ng Where is that written? Not familiar with any screen that uses that cutoff (usually 50).
