Well this is my 2 cents worth.
My ex bf has a severe pot addiction.
Back at the beginning of December o8 he said he was quitting as he was incredibly abusive towards me with his paranoia. So he supposedly did. But he was smoking at work. Anyways for 6 months I thought he had quit but he hadn't. Finally admitted he hadn't after he walked out and left. Then said he quit and was going to get help, gave him another chance.
Last weekend the s$%t hit the fan again and I was called a s$%t again and accused of being unfaithful (all made up in his THC soaked paranoid brain).
My point is, "How do you know when an alcoholic/addict is lying?"
"When their lips are moving>"
Unless they get into treatment and work a program get a sponsor all that stuff there really is no hope.
