<human>: I have been with my friends for about 6 years. One of my friends I even grew up with and went to pre-school together with. I am currently in the hospital treating my depression and I am beginning to realized that my friends will not help me with my treatment. 

Most of my friends are into smoking pot. I would normally be ok with this, but they smoke every day of the week. I used to smoke every day of the week as well but this is something I am changing. My one friends since I knew from pre-school smokes more pot than anybody I know. I feel like he is still trying to cope with the loss of his brother about 3 years ago. I do not want to be a part of that lifestyle anymore, and would like to make new friends but I who don't binge drink or constantly smoke weed every day, but I don't know what to do about my old friends.

Provide a brief overview of the text.
<bot>: Friends are into heavy drug and alcohol use, I am trying to treat my depression so I am no longer able to do that kind of stuff. What should I do about my friends?
