Cause and effect.
There is no way you or anyone else would know if pot caused that young man to go down the path he did.
It could have been the people he met, or the books he was reading, or any number of things put together.
Or just maybe for the first time in his life he felt he was able to think for himself and he made the life choices you wrote about.
Who knows what lurks in people’s hearts and minds.
Your right. I think it started with that college and his choices..... His dad is a retired colonel in the Air Force. He's a really good guy. He sold his properties in Fl and NE to got out of the city and bought 25 acres overlooking lake Oahe. He use to fish with his son a lot and hoped his son would come out fish, help him oversee the house that's being built.... Sometimes we think they hit rock bottom but he apparently hasn't. It's all in Gods hands.
