My son is 24 and I am afraid he is using some kind of drugs. He was arrested because he gave a girl a ride and she had meth and paraphernalia with her. He passed a hair follicle drug test and they dropped the charges against him. But he continues to spend time with people who are doing drugs. He wears a knife on his belt and has weapons in his vehicle. Two days ago my house was robbed because one of the people he is around broke in after he had them over when we weren't there. The last 3 times I have seen him he has been unable to stay awake. He was dozing off while eating. He went in and laid down and slept for several hours. He denies any drug use and brought up the drug test that he passed. He is suffering from depression. He says he doesnt sleep good. He had gastric sleeve surgery so i cant tell if he is skinny from that or from drug use. He hasn't worked since his arrest except for odd jobs.
