Controlled Substances Act List
Drugs that either require a licensed physician to dispense a prescription for, or illicit street drugs or other illegal chemical substances, are known as “controlled substances” in Massachusetts. Controlled substances are governed by Massachusetts General Laws Chapter 94C, and they are classified within five separate categories, based upon their specific chemical composition: Those five categories are:
- Class A Substances: Encompassing Heroin, GHB (and other "designer drugs"), Morphine, and Ketamine (also known as "Special K").
- Class B Substances: Involving Cocaine, Ecstasy, Amphetamines ("Speed"), LSD, PCP, Methamphetamines ("Meth"), and prescription medications like Oxycodone (Percocet & Percodan).
- Class C Substances: Typically involving prescription tranquilizers and narcotics like Clonazepam, diazepam (Valium), and Hydrocodone (Vicodin); as well as mescaline, mushrooms ("psilocybin"), and similar hallucinogenic substances.
- Class D Substances: Commonly associated with Marijuana and Phenobarbital.
- Class E Substances: Encompassing prescription medications containing lesser amounts of Codeine, Morphine, or other Opiates.
If an individual in Massachusetts is found by police or law enforcement authorities to be in possession of any controlled substances from these classes, (with the notable exception of one ounce of marijuana or less,) severe criminal penalties apply. Note: When criminal charges are brought alleging prescription drug violations, it is required that the defendant not be in possession of a valid prescription written by a licensed physician in Massachusetts.
