Massachusetts Drug Possession Laws

Whenever you have illicit drugs in your possession, there's a possibility of being arrested and facing charges. This is true in Massachusetts except for the possession of small amounts of marijuana. Massachusetts has legalized marijuana and decriminalized marijuana possession for possession of less than an ounce; this is considered a civil citation and no criminal charges will result. However, despite the drug's legality, if you possess more than an ounce, you can be charged with possession in Massachusetts.

Definition of Possession in Massachusetts

Massachusetts law prohibits any individual from knowingly or intentionally possessing a controlled substance unless it was obtained from a valid prescription. To be guilty of the offense, you may either have actual possession of the substance, meaning that you're holding the drugs in your hand; in your pocket; or otherwise under your control, such as your car's glove compartment. Regardless, you must have knowledge of the drugs to be guilty of a possession charge.

However, the definition of "possession" is much broader regarding heroin. Massachusetts criminalizes knowingly being in the presence of heroin as a separate charge from possession. This means that if you're present at someone's home or apartment and you know that heroin is anywhere on the premises, you can be charged.

Classification of Controlled Substances in Massachusetts

Your criminal charge is based on the type of drug that you possess. The controlled substances are designated into "classes" ranging from Class A (the most dangerous drugs) to Class E, which are considered the least dangerous. Possession of Class A drugs result in greater penalties; Class E carry the least serious penalties.
