How Do I Get My Son Off Drugs?

I just found out last night from a very good source that my ex has started using meth. What can I do to help my son? Thanks in advance.

I recently found out my son has been smoking crack, and he cant stop. I was curious as to what it feels like to make someone not want to stop. So if youve tried crack, did you stop and what does it feel like that people like it so much? Thanks

Should i say something, I don’t wanna hurt his chances of being popular. I want him to be able to go to all the underage drinking parties.
