Relates to the possession and sale of methamphetamine

S 1519 aligns penalties for methamphetamine possession and sale with those for heroin and cocaine by adjusting weight thresholds in New York's penal law. It lowers the weight threshold for methamphetamine possession from 1 gram to 100 milligrams (matching existing heroin/cocaine standards) and reduces sale thresholds from 0.5 ounces to 1 gram. These changes directly affect individuals possessing or selling methamphetamine, as the bill modifies specific legal definitions in sections 220.06, 220.09, 220.16, 220.21, 220.39, and 220.43. The law applies only to offenses committed on or after its effective date, leaving prior cases governed by older penalties.
