Study shows crystal meth can keep flu at bay1/11/2013
As well as rotting your teeth and turning you into a jerk, crystal meth may also be an effective flu preventative. Researchers from the Taiwanese National Health Research Institutes and the University of Regensburg in Germany studying the drug's effects on flu found that human lung cells exposed to a small dose of the drug were less likely to be infected by the virus. The surprising results are at odds with evidence that chronic use decreases immunity. But before you go all Walter White and rush out to the garage, the researchers noted that only one strain of flu had been tested and others may not have the same response. [Source]
