Notes:

  1. OSHA does not have a PEL for methamphetamine.
  2. Methamphetamine is a Schedule II controlled substance (21 CFR 1308.12), which is approved by the FDA for the treatment of attention deficit disorder with hyperactivity and exogenous obesity.
  3. The mean elimination half-life of methamphetamine was approximately 11 hours by intravenous, intranasal and inhaled (smoked) routes of administration in eight experienced users.
  4. Injuries have occurred to first responders (police officers, emergency medical staff, fire fighters) from chemicals used in illicit methamphetamine-producing laboratories, including hydrochloric acid, ammonia, phosphine, and diethyl ether.
