I found a bong in my teens room. He had historically been using marijuana and has passed multiple Urine based drug tests. Claims it is CBD not THC that he is smoking. I still do not like it. I have the remnants of the CBD/THC leaves in the bong. Does anyone know of a lab that I can have test them? I want to trust him but I found synthetic urine in his room last week. I am concerned that he is good at tricking the urine tests. Thanks in advance for any help.
