A nurse told me that they see lots of exotic third world diseases in our charity hospital. TB is epidemic and one can get it standing in line in the grocery story, docs have told me. One night late I came on some research showing the only thing effective against the drug- resistant TB was nicotine. So, now, when docs challenge me about smoking, I say I'll stop when they control
TB. In the meantime I am using it as a preventative. LOL
I'm not against legal, controlled immigration. But, among other things, when we have thirty million illegals that are not being tested for any contagious diseases, that to me is a serious problem. Also must be noted, that all illegals are not from just Central and South America, but tens of thousands from Asia and elsewhere visiting on visas, then just don't ever go back. The question must always be who, what and where, otherwise why have a Homeland Security or borders? Why be a sovereign nation?
I'm not a smoker, so I can't lend anything to your question! However, common sense would tell me/you to take my chances in a controlled TB environment, than uncontrolled.
