Mr. Jones filed a lawsuit against the company he worked for. He claimed that the company he worked for was drugging him to make him a better worker. He claimed that the coffee the company provided contained a drug called Trimethylxanthine. Trimethylxanthine is an addictive drug that increases alertness, improves concentration, and gives you a euphoric feeling. It operates using the same mechanisms that amphetamines, cocaine, and heroin use to stimulate the brain only to a lesser degree. When the coffee was tested it was found that it did contain large amounts of Trimethylxanthine. But, Mr. Jones did not win his lawsuit. Why?
