How Do I Get My Son Off Drugs?

I have been weaning off a nasty cocaine addiction and just addiction in general, mostly because I have finally seen the agony and pain I have put my two biggest supporters, my parents, through.

Lately, though, and especially after relapsing and pulling some stupid shit, my mom has been quite talkative and perky, happy go lucky more or less. She is usually down, concerned, always agonizing over the situation. Not good for her.

This sounds good, but I found in her Internet history she had looked up caffeine injections. Now, for the sake of me knowing the pain it puts everyone through and trying to get clean, are there any legal drugs that she could be taking to make her this passive with the situation? I doubt depression pills, anyone know about anything else?

Thank you in advance.

I rent a house with my wife and 1 year old son. The former owners of the house smoked a lot. Before we moved in, my wife and I wiped the walls down with cleaning solution and they just dripped black water when we sprayed the cleaning solution on them. It took a long time to clean them but the smell is MUCH better now. Anyway, my mother called me today and asked me if I had ever thought that this house was a former meth lab because of the smell. From what I have read, the smell in a former meth lab is very chemical. We’ve never smelled anything other than just stale smoke in this house. My mother covertly swabbed some dust from the cracks of the house and tested it with some meth tester. It didn’t register positive but eventually did a few days later. We really doubt that it was a meth lab but we don’t know what it would smell like. Is there a way to determine for sure? I’m afraid the landlords may just lie if we ask. Would the police department test the house for free?
