What Does Possession of a Controlled Substance Mean in Massachusetts?
Under Massachusetts General Laws Chapter 94C, Section 34, Possession of a Controlled Substance is defined as knowingly or intentionally possessing a substance categorized as controlled without legal authorization (e.g., prescription or license). Controlled substances in Massachusetts are divided into five classes (A through E), and penalties vary based on the class of drug involved, your criminal history, and the specific facts of your case.
Some common illegal drugs in these cases include:
- Heroin (Class A)
- Cocaine (Class B)
- Methamphetamine (Class B)
- Oxycodone or Percocet without a prescription (Class B)
- Xanax or Valium without a prescription (Class C or D)
- Marijuana (Class D)
First-time offenses for possession may allow for dismissal or probation under certain circumstances, but second or subsequent charges can carry harsher consequences, including jail time and a permanent criminal record.
Why You Need a Massachusetts Defense Attorney with Drug Crime Experience
Possession charges are not always straightforward. An experienced Massachusetts drug defense attorney will evaluate the legality of the search and seizure, whether you were truly in possession, and whether the substance was correctly identified. Our criminal defense law firm knows how prosecutors approach these cases and how to challenge their evidence.
Having a former prosecutor on our team gives our clients insight into how cases are built—and how they can fall apart. We understand how to question every aspect of a case, from lab testing to the arresting officer’s report, to give you the best defense available.

Potential Penalties for Possession of a Controlled Substance
The consequences for a Possession of a Controlled Substance charge in Massachusetts depend on several factors, including the type of substance, the amount involved, and your prior criminal record. Massachusetts law classifies controlled substances into five categories (Class A through E), and each class carries different levels of penalties.
Here’s a general breakdown based on Massachusetts General Laws:
- First-Time Offenders: In many cases, individuals facing their first charge may be eligible for probation or alternative resolutions. However, the law allows for up to one year in jail and fines of up to $1,000, even for a first offense.
- Repeat Offenses: A second or subsequent conviction often carries more severe consequences. These may include mandatory jail time, higher fines, and fewer diversion options.
- School Zone Enhancements: If the alleged possession occurred within 300 feet of a school, Massachusetts law imposes additional penalties. Under G.L. c. 94C, § 32J, individuals may face enhanced sentences, even if the school was not in session or the drug possession was not connected to students.
The stakes are high in these cases, and having a knowledgeable criminal defense attorney can make a significant difference. With the right legal strategy, it may be possible to reduce the charges, avoid jail time, or have the case dismissed entirely.

Not always. Simple possession is usually a misdemeanor for a first offense, but repeat offenses, or possession with intent to distribute, may be charged as felonies.
Can I be charged even if the drugs weren’t mine?
Yes, you can be charged if you were in “constructive possession”—for example, if drugs were found in a car or home you had control over. An experienced criminal defense attorney can challenge this.

Controlled substances are classified under state law from Class A (most serious) to Class E (least serious). Examples include heroin, cocaine, meth, and prescription medications without a valid prescription.
