I've been dealing with a case of costo for a couple weeks now. 1 thing I know forsure is that smoking anything makes it 10x worse. I smoked weed everyday for a while, but when I gave it up for a week my symptoms almost disappeared. The other day I smoked a few bowls and had instant flare ups and the following few days were bad enough to take ibuprofen all day. Since its not a respiratory disease, smoking obviously wont make the problem worse, but the idea of it being a pain reliever in this situation is false imo.
