Relating to the use, possession, delivery, or manufacture of testing equipment that identifies the presence of a substance listed in Penalty Group 1-B.

SB 540 exempts individuals from certain legal restrictions when using, possessing, delivering, or manufacturing testing equipment designed to identify substances in Penalty Group 1-B (such as cocaine, methamphetamine, or heroin). This directly affects laboratories, law enforcement, and healthcare providers who use such equipment for legitimate testing purposes. The bill amends the Health and Safety Code to explicitly state that these activities are not subject to the standard prohibitions. It applies only to offenses occurring on or after September 1, 2025, with prior offenses governed by existing law.
