Faint line of drug test

Hello, I'm 17 years old and my parents gave me a drug test today. I put some toilet water in the cup before I took the test. I didn't see the results but I had a faint line for TCH. They are sending it into the lab. Will this be a pass or fail?
I need to know because if I'm going to fail I need to tell my parents the truth but there is always a change I might pass.

 

if theyre sending it to a lab, you failed if there is any faint line.

 

It will either fail or come back as diluted. In the eyes of the gotvernment they are one in the same. I would just come clean.

 

Thank you.

 

Good luck. If they're testing you they obviously have a reason too...
Honesty is the best policy.

 

good luck let us know what happened. it doesn't sound good though

 

If something fails in a home test and gets sent to the lab it will always still be positive. And sometimes the lab will detect at smaller amounts and test for more things.

 

Your parents sound like jerks

 

Your toilet smokes weed?
