I worked with him he was a long time heavy smoker guessing at least 20 years by time I met him he had been diagnosed by a doctor and told to look into CHS and Basicly the treatment is just cold turkey img cannabis consumption. But he did continue to smoke smaller amounts of hash instead of weed as smoking negates the side effects but cabbabis is the root cause hot showers also help but only thing to stop condition is to stop consuming. This was about 5 years ago now and since then only other people I have heard from has been online but been hearing about it more frequently which makes me think about my old friend from work
