 Chemical supply companies could be prosecuted for selling chemicals to people who make methamphetamine.By 2000, in the Inland Northwest, and in much of the West United States, methamphetamine was the favored hard drug, surpassing crack and cocaine as the stimulant of choice, as it offered 3.5 times more potency, and a much longer half life.Heroin use was also being surpassed with methamphetamine, which unlike heroin, is not severely cut and reduced in potency with other additive substances.
