People are going through a lot, it only takes grace to speak people out of the situation they chose to remain. He is addicted to drugs already, putting himself in that condition shouldn't be a surprise cos he is acting on the influence of cocaine.

It's sad though, but what ever made him chose that kind of life is not worth it.

He is putting his life at risk and his family/ friends are troubled. I feel sorry for your friend I hope he gets back on his feet with a renewed lifestyle.

It might be difficult, but I advise you talk to him, make him understand that there is hope for a better life, help him in the little way you can be it financially, emotionally and spiritually.
People are going through a lot that is certain. May we not take our lives no matter the situation surrounding us.
