Melody Petersen, writing at MSNBC, brings up the issue of US soldiers serving while on heavy medication. We are all aware of soldiers being given amphetamines and the drug abuse problems that arise in arenas of war, but data suggest that over 10% of actively serving soldiers are on anti-depressants, anti-psychotics and tranquilizers. Given that it is questionable for a civilian to drive a car, let alone operate heavy machinery, how much sense does it make to entrust serious firepower weaponry to soldiers with compromised thinking ability?
