Resolved Question:

I put an additive called Klear Test in my specimen at my random drug test. What do you know about it? I'm scared to death it will come back positive for THC and I will lose my job, although I never use at work.

When had you last used?

How often did you use prior to the test?

When was the test?
Customer: replied 5 years ago.
I had used the day before. The test was Thursday, February 23, and I was using fairly regularily in the evenings.
Expert:  Family Physician replied 5 years ago.
Unfortunately, there is really no scientific evidence that Klear (or any other additive) will mask the drugs without causing the specimen to be reported as "adulterated" (tampered) - which is treated the same as a positive.

The company advised that it would even pass an GC/MS test. Is your answer still the same?
Expert:  Family Physician replied 5 years ago.
The fact that the company makes such claims really does not change my answer. Companies that sell products marketed as a way to cheat on a drug test are not what one would consider "reputable" corporate citizens. The fact that such a company makes such a promise really doesn't make it fact.

The medical scientific evidence is not available to support their claims.... and what is someone going to do when it turns out to be wrong - sue the company?
