I found this article: http://arizona.openrepository.com/arizona/handle/10150/185511 Heres a quote from it: I recently (before I came across that article) tried smoking this herb to satisfy a spontaneous urge so this gets me wondering if smoking this substance could be used to combat lung and nasal infections. I'm not suggesting anyone try this as that would be reckless and dangerous because the plant may contain harmful compounds and burning them may produce additional harmful degradents but I think its worth researching. They isolated numerous compounds from this species of salvia but the most promising one seems to be 16-hydroxy-12-methoxy-methylcarnosate. I can't find any info on this compound but I suppose we could make an educated guess on what the boiling point and decomposition point of the compound may be. I'm a chem major but I'm in no way experienced enough to make a good estimate on something like that. Any takers? EDIT: Also, why are there not more smoked or nebulised antibiotics in use? I'd assume intravenous or inhalation would be a superior route for many infections because you avoid wiping out your gastrointestinal fauna of friendly bacteria like you do when taking them orally. I'm guessing its down to convenience. More convenient for a person to pop a pill than inject themselves. Inhalers are pretty convenient though. I've never heard of smoking being used in conventional medicine, I wonder why. Inhaling the vapour of a volatile drug compound is an effective ROA.
