Hello! Yes cannabis can help decrease chronic pain. I would recommend to try a 1:1 CBD to THC sublingual tincture and a topical salve. Rub the salve on the places you have pain. I would start with a low amount of the sublingual tincture, perhaps 1-2 drops under the tongue and increase slowly if necessary. I would avoid inhaling cannabis smoke or vapor considering your history with chronic obstructive pulmonary disease (COPD). It’s important to do some gentle stretching and consider some physical therapy and other alternative methods to holistically treat your pain. Best of luck
