But he hid it and lied about it and this is what is most concerning to me, which I did tell him. But he just keeps saying it is not the same as drinking and it is no big deal.
Of course the lies are most concerning, as they should be. Lying IS a big deal. A huge deal. Hiding his drug use is a big deal too. If it wasn't that big of a deal then why not give it up?
Sadly, the odds are excellent he'll progress to more pot, maybe other drugs, most likely drink again. That's how addiction works. Addicts can't moderate.
I'm so very sorry you're in pain.
Praying for you, jj, and your child.
