I took 160mg of MDMA about 3 weeks ago. I have a hair test for school within weeks will I pass? It is being done by psychemedics.

With a one-time use you are probably okay. These tests are designed to test for use over time.

A hair drug test is meant to show consistent use over time. A 1.5 inch sample of hair, cut at the scalp line, will go back 90 days. You should have no problem passing a hair test especially since Psychemedics uses a test with a high cutoff level.

So I've hear many different stories. Like LSD can be found in your spine. I would like to see if anyone on hear knows anything. Also I've heard that they can test for it on hair. What are the chances that is true and the odds of my school testing for it.

Yes, it can be found in your spinal fluid, but no one is going to go as far to do a dangerous lumbar puncture for a drug test.

Yes, heavy use can be detected in your hair. No one here knows what the chances are of your school testing for it. This is a global website and we don't know your school policies.

The easiest way to pass any drug test is don't put drugs in your body. That's plain foolish and an unnecessary worry when you KNOW a drug test is coming. Often the tricks to hide the drugs is more harmful than good, and likely does no good, and still have the next test, that you KNOW is coming, to worry about.

Do it right the first time and don't worry about failing a drug test (that you KNOW) is coming.
