Should I have a welfare check done on my son?

First of all I used to be a cop. I know what they will, won't, can, or cannot do. I was asking from a mothers and a situational perspective. It IS there job just like it was mine when I was a cop. I called the police on my son and I would do it again. If he wants to smoke pot he can do it somewhere else, it will not be tolerated in my home. I will not possibly lose my daughter who is a minor because my son doesn't care about anyone but himself. Thanks to all who actually took the time to READ my question BEFORE answering. Tough love is tough...But It wouldn't be done if we didn't love them.
