Class B Drugs in Massachusetts: Penalties, Trafficking, and Zone Enhancements

Class B drug penalties in Massachusetts range from up to one year in a house of correction for a first simple possession offense to a mandatory 12-year state prison sentence for trafficking 200 grams or more of cocaine or methamphetamine. Chapter 94C of the General Laws sets the tiers, and where a case lands on that spectrum depends on the substance, the weight, whether distribution is alleged, prior record, and where the conduct occurred.

Which Drugs Fall Under Class B

Section 31 of Chapter 94C sorts controlled substances into five classes based on abuse potential, accepted medical use, and risk of dependence. Class B captures drugs with high abuse potential that still have some recognized medical application. The substances most often charged under this class are cocaine, methamphetamine, oxycodone, amphetamines (including Adderall held without a prescription), and methylphenidate (Ritalin).¹

A few entries catch people off guard. LSD, PCP, and MDMA (ecstasy) sit in Class B as hallucinogens under subsection (e), not in a lower class as the federal schedules might suggest.¹ The list also includes raw materials used to make methamphetamine, such as phenyl-2-propanone (P2P), along with dozens of synthetic opiates including methadone, levorphanol, and anileridine. State classifications do not line up perfectly with the federal Controlled Substances Act, so a substance may carry different consequences in state court than it would federally.²

Simple Possession Penalties

Section 34 governs possession of a Class B substance without a valid prescription. A first offense carries up to one year in a house of correction and a fine up to $1,000.³ First-time defendants with no record often receive probation, community service, or a continuance without a finding rather than jail.

A second or subsequent possession conviction raises the ceiling to two years in a house of correction and a $2,000 fine.³ The statute counts prior Section 34 convictions and any prior felony conviction under Chapter 94C, so a past distribution conviction pushes a later possession charge into the enhanced range.

Distribution and Manufacturing Penalties

Section 32A applies to manufacturing, distributing, or possessing a Class B substance with intent to distribute. These are felonies. A first offense can draw up to ten years in state prison or up to two and a half years in a house of correction, with a fine of $1,000 to $10,000.⁴ Within that range, judges weigh factors such as quantity, violence, and cooperation.

A second or subsequent distribution conviction carries up to ten years in state prison and a fine of $2,500 to $25,000.⁴ Until the state’s 2018 criminal justice reform, repeat Class B distribution convictions required a two-year mandatory minimum prison term. That requirement was repealed, and judges now have full discretion up to the statutory maximum, including probation for a qualifying defendant.

Cocaine and Methamphetamine Trafficking

Once the quantity of cocaine or methamphetamine hits 18 grams, the charge becomes trafficking under Section 32E. Trafficking is where Massachusetts sentencing turns severe. The mandatory minimums below survived the 2018 reforms and cannot be suspended or reduced:

18 to 35 grams: 2-year mandatory minimum in state prison, 15-year maximum. Fine of $2,500 to $25,000.
36 to 99 grams: 3.5-year mandatory minimum, 20-year maximum. Fine of $5,000 to $50,000.
100 to 199 grams: 8-year mandatory minimum, 20-year maximum. Fine of $10,000 to $100,000.
200 grams or more: 12-year mandatory minimum, 20-year maximum. Fine of $50,000 to $500,000.

These weights count the total mass of any mixture containing the drug, not just the pure substance.⁵ A 20-gram bag of heavily cut cocaine triggers the trafficking threshold even if the actual cocaine content is a small fraction of that total.

School and Park Zone Enhancement

Section 32J adds a consecutive two-year mandatory minimum for drug offenses committed within 300 feet of a school (between 5:00 a.m. and midnight) or within 100 feet of a public park or playground. The 2018 reforms narrowed this enhancement significantly. It now applies only when the defendant also meets at least one aggravating condition during the offense:⁶

Used or threatened violence, or possessed a firearm or other weapon.
Directed the activities of another person who committed a drug felony.
Sold directly to a minor or recruited a minor into the operation.

The two years run consecutively to the sentence on the underlying drug offense, meaning they begin only after that first sentence has been served. A fine of $1,000 to $10,000 may be added but cannot replace the prison time.⁶ Before 2018, this enhancement applied to any drug offense in the zone regardless of circumstances.

Consequences That Reach Beyond the Sentence

The criminal sentence is only part of the picture. A Class B conviction triggers federal consequences that often last longer than the sentence and cause more practical damage.

Firearms

Federal law bars the sale of firearms or ammunition to anyone who is an unlawful user of or addicted to a controlled substance.⁷ A felony drug conviction independently costs the right to possess firearms under both federal and Massachusetts law.

Public Housing

Public housing authorities must deny admission for at least three years to anyone evicted from federally assisted housing for drug-related activity. A household member convicted of manufacturing methamphetamine on the premises of federally assisted housing is permanently barred with no path to reinstatement.⁸ A housing authority can also deny admission on reasonable cause that a household member’s drug use threatens other residents, even without a prior eviction.

Immigration

For non-citizens, a Class B conviction can be devastating. Any controlled substance conviction after admission to the United States makes a non-citizen deportable, with one narrow exception for a single offense involving 30 grams or less of marijuana for personal use.⁹ Cocaine, oxycodone, and methamphetamine convictions get no such exception. The same conviction also makes a non-citizen inadmissible, blocking future visas, green card renewals, and reentry after travel. Expungements and pardons generally do not clear a drug conviction for immigration purposes, and a suspended sentence or probation still counts as a conviction.¹⁰ Non-citizens should consult an immigration attorney before entering any plea.

Commercial Driver’s License

Operating a commercial motor vehicle under the influence of a controlled substance brings a one-year CDL disqualification for a first offense, three years if hazardous materials were being transported, and a lifetime disqualification for a second offense. Using a commercial vehicle to commit a felony involving drug manufacturing or distribution carries an immediate lifetime ban with no reinstatement.¹¹
