Funded in part by Taser International, a recent study was done to learn the effects of being tasered while on methamphetamines
. Since someone would probably complain about researchers going around and tasering meth addicts, they used sheep instead. From the article: "The less-lethal device of choice was the Taser X26, a standard law enforcement tool which can fire at suspects from a distance of 35 feet. Researchers shocked sixteen anesthetized sheep after dosing the animals with an IV drip of methamphetamine hydrochloride. Some of the smaller sheep weighing less than 70.5 pounds suffered exacerbated heart symptoms related to meth use. But neither the smaller nor larger sheep showed signs of the ventricular fibrillation condition, a highly abnormal heart rhythm that can become fatal."
