Home Drug Tests

Should I buy those home drug tests and randomly test my son. He lives with me. I'm new to all this. This is my first time to post.
Hi,
How old is he?
Thanks for replying. He is 32.
sometimes the reality of it all is hardest and to think that you should have to do this with a 32 year old is a terrible thing for you as a mother of a grown man to even have to deal with, If he is wanting help then by all means do what you can. but at 32 what could the consequences actually be,, would you tell him to leave your home or seek help. Save your money,, and propose that to him. If he wants to be clean he will seek help, If he doesn't then he will move out, I think that he shouldn't be putting you threw his hell. Good luck !!
