What are the cutoff limits for probation drug testing for THC?

What are the limits that make for a positive urine test for THC (both initial screen and confirmation) that probation departments use? Are these limits the same for every county?

It is common to see a sensitivity level/cut-off level of 50 ng/mL for marijuana/cannibas. There is no a zero tollerance with probation departments. There is always the possibility of a false-positive and some courts and labs use different levels. If you are looking at a possible violation of probation (VOP), you should consult with an experienced criminal defense lawyer as soon as possible. A good attorney may be able to help you avoid facing the VOP all together.

I encourage you to use to find a 10.0 rated criminal defense lawyer. Most retained criminal defense attorneys will offer you a free telephone consultation. Feel free to consult with an attorney in any part of Michigan as it is not uncommon for criminal defense lawyers to travel throughout the state.

There is a zero tolerance for all drug testing. Generally it is the same for all counties.

I agree with Mr. Dickstein. Also, marijuana will stay in a person's body, for testing purposes, for about 30 days. A better drug test will provide the amount of nanograms of THC, so the Court can have a baseline. The amount of nanograms will reduce over time as long as the user does not continue to use.
