What is the likelihood that someone can use Meth “recreationally” several times a week and not be hooked?

My ex recently came back in the picture claiming that he dropped out of my sons life 6 months ago because he went down the wrong road and started hanging around bad people and started using meth. He said “it’s not like I’m addicted or anything. I quit a week ago. I just used it to help me deal with the feelings I was having about my life sucking so bad.”

Would you buy it? Believe him?
