Although salt is often accused of being an addictive—and even deadly—ingredient in the typical American diet, the savory compound is perfectly legal in any amount. Unless it's used as a weapon.
Last week, the Knoxville Police Department received a call reporting a potential poisoning. When officers arrived at the caller's residence, she told them that she believed someone was attempting to poison her with a substance placed in her salt container. As officers pressed her for more information, the victim explained that every time she used the salt to cook, she experienced a sudden wave of headaches and felt sick to her stomach. Although she had no solid proof of the poisoning-by-salt scenario, she said she believed she knew the responsible individual, with whom she had experienced a recent dispute over rent.
After leaving the residence, the KPD narcotics unit tested the salt for foreign chemicals. Result: Besides the expected sodium chloride, they found Ecstasy and methamphetamine. Which goes to show: You're not paranoid about salt if you're right.
