Some time ago, Gs sent me a link to one of Racaniello's blog posts about interferons and secondary pneumonia after influenza. His post ended with: "Nevertheless, it might be possible to avoid secondary bacterial pneumonia by treating influenza patients with drugs that inhibit type I IFN."

So I searched for drugs and type I INF and found this study: Cocaine causes increased type I interferon secretion by both L929 cells and murine macrophages. "Here, we present evidence that cocaine stimulates the secretion of an antiviral product that is neutralized by anti-interferon (anti-IFN). These findings further support our previous research demonstrating an antiviral activity of cocaine in vitro. The relevance of this activity to viral infections in general remains to be determined."

That surprised me because I really hadn't thought about how cocaine impacts our immune system. We have a lot of crack/powder cocaine usage in my area but that particular aspect never crossed my mind. My county is also the #1 meth producer in the state and the cost of removing the chemical residue left behind in homes from meth production can run into thousands of dollars.
Then I had to wonder about all the other drugs we use recreationally (US leads the world in that type of drug usage) and I found a lot of other studies on how drugs affect our immune systems. For instance, anabolic steriods may have a negative effect for women's immune systems due to hormonal imbalance. Then it's estimated that in 2007 almost a million kids used inhalants; I suppose the type of chemical in the inhalant would determind any damage to the lungs/immune system.
Then I took my speculation further and wondered if there was any connection between drug usage during wartime and pandemics. I was really shocked at the amount of drug usage during the 1918 period. I haven't found much yet about the Korean war but Viet Nam and Agent Orange always stay in my mind.
If anyone is interested further, here are the threads I started at gs's forum. Anything can be brought over here, too.
