Spouse on drugs?

Patricia.

We have been together for 8 years. We have a 5 & 2 year old. He has always smoked pot. I learned to deal with it. I quit my job a few weeks back, and he has changed. Something is going on.

1. He’s out of it all the time. His family is even making comments about it.

2. He’s defensive about everything I say.

3. He’s getting caught in lies. Swears he tells me stuff he never told me. He has always been honest about going to “re-up” and who he was going to, but all of a sudden he lies about it..

4. His group of friends is shifting. He’s not hanging out with his usual friends much anymore...

I don’t know what to suspect. Any advice is welcome. It’s really effecting our family, and I hate this.
