Maryland Controlled Substance List: Schedules, Penalties, and Defenses

Maryland’s controlled substance schedules and penalties are set out in Title 5 of the Criminal Law Article, which sorts drugs into five schedules that mirror the federal system and assigns punishments based on the schedule, the type of offense, and any prior convictions. Simple possession of any scheduled substance without a valid prescription is a misdemeanor, with a first offense carrying up to one year in jail and a fine up to $5,000.¹ Distribution is a felony, with penalties ranging from 5 years for a Schedule III, IV, or V substance to 20 years for a first offense involving a Schedule I or II narcotic like heroin or fentanyl, plus additional enhancements in specific cases.

The Five Schedules and What’s on Them

The schedule a drug sits in decides how heavily distribution is punished, so the categories matter well beyond the labels.

Schedule I

Schedule I drugs have high abuse potential, no accepted medical use in the United States, and no accepted safe use under medical supervision. Heroin, LSD, MDMA, and certain synthetic fentanyl analogs sit here.² Maryland also treats controlled substance analogs as Schedule I when intended for human consumption: any substance with a chemical structure substantially similar to a Schedule I or II drug that produces comparable stimulant, depressant, or hallucinogenic effects. Prosecutors don’t have to wait for a new street drug to be formally scheduled before charging.³

Schedule II

Schedule II drugs also have high abuse potential but carry accepted medical uses, often with tight prescribing restrictions. Cocaine, methamphetamine, fentanyl, oxycodone, and morphine all fall here.² Distribution penalties for Schedule II narcotics match those for Schedule I narcotics, which is why the two schedules are usually discussed together in sentencing.

Schedule III

Schedule III covers substances with less abuse potential than Schedules I and II but real dependence risk. Ketamine, anabolic steroids, and medications containing limited amounts of codeine belong here.²

Schedule IV

Schedule IV drugs have lower abuse and dependence potential and are commonly prescribed. Alprazolam (Xanax), diazepam (Valium), and zolpidem (Ambien) are typical.²

Schedule V

Schedule V holds the least restricted controlled substances, typically medications with small amounts of narcotics. Cough syrups containing limited quantities of codeine are the familiar example. Distribution penalties for Schedule V match Schedules III and IV.

Possession Penalties

Possessing any controlled substance without a valid prescription is a misdemeanor. Penalties climb with prior convictions:¹

First offense: up to 1 year in jail, a fine up to $5,000, or both
Second or third offense: up to 18 months in jail, a fine up to $5,000, or both
Fourth or subsequent offense: up to 2 years in jail, a fine up to $5,000, or both

These maximums are the same whether the drug is Schedule I or Schedule V. That’s a sharp contrast with distribution, where the schedule changes the exposure dramatically. Cannabis has its own separate structure, addressed further down.

Possession can be actual or constructive. Actual possession means the substance was found on your person. Constructive possession applies when you knew about the drug and had the ability to control it, even without physical contact. Courts weigh proximity to the substance, ownership of the place it was found, and any statements made to police.⁴

Ways to Avoid a Conviction

Two Maryland mechanisms let some defendants leave a possession charge without a permanent conviction on record.

Probation Before Judgment (PBJ) lets a court defer entering a conviction and place the defendant on probation instead. Successful completion ends in a discharge without a conviction, which changes the picture for employment, housing, and immigration. For controlled substance offenses, PBJ is generally available for a first-time offense. A defendant with one prior possession conviction or PBJ can still get PBJ a second time, but only if the court requires graduation from drug court or completion of a substance abuse treatment program as a condition of probation.⁵ PBJ is not available for distribution or manufacturing charges.

Drug Treatment Courts run 15 to 18 months across multiple phases and combine intensive rehabilitation services with court supervision. Participants who finish can avoid incarceration or have their sentences modified. Eligibility generally requires that the charges stem from a substance use disorder rather than high-level trafficking.

Distribution and Manufacturing Penalties

Distributing, manufacturing, or possessing with intent to distribute is a felony. A single transfer counts as distribution whether or not money changes hands. Maryland law splits Schedule I and II into narcotic and hallucinogenic categories, and the narcotic penalties are the harshest in the drug code.

Schedule I and II Narcotics

Distribution of a Schedule I or II narcotic, including heroin, cocaine, fentanyl, oxycodone, and morphine, is punishable on a first offense by up to 20 years in prison, a fine up to $15,000, or both.⁶ Repeat convictions carry mandatory minimums the judge cannot suspend, with no parole during the mandatory portion:

Second conviction: mandatory minimum of 10 years, fine up to $100,000
Third conviction: mandatory minimum of 25 years, fine up to $100,000
Fourth conviction: mandatory minimum of 40 years, fine up to $100,000

The mandatory minimums cannot be reduced.⁷

Fentanyl and Heroin Enhancement

Distributing fentanyl or heroin triggers an additional penalty on top of the standard narcotic sentence. A conviction under this enhancement adds up to 10 extra years of imprisonment, and that sentence runs consecutively.⁸ A first-time fentanyl distributor could face up to 30 years total: 20 under the base statute plus 10 under the enhancement.

Schedule I and II Hallucinogens

Distribution of specific hallucinogens, including LSD, PCP, and MDMA in quantities of 750 grams or more, is punished under a separate statute. A first offense still carries up to 20 years and a $15,000 fine. But repeat offenses do not trigger the same mandatory minimums that apply to narcotics.⁹ Second offenders face up to 20 years and $15,000, third offenders up to 25 years and $25,000, and fourth offenders up to 40 years and $25,000.

Schedule III, IV, and V Substances

Distributing a Schedule III, IV, or V substance is a felony punishable by up to 5 years in prison, a fine up to $15,000, or both.¹⁰ The gap with Schedule I and II narcotics is wide. Distributing ketamine or anabolic steroids maxes out at 5 years; distributing heroin or fentanyl maxes out at 20 before enhancements.

Drug-Free School Zones

Manufacturing, distributing, or possessing with intent to distribute within 1,000 feet of an elementary or secondary school triggers enhanced penalties on top of the standard sentence. A subsequent violation in a school zone carries a mandatory minimum of 5 years, a maximum of 40 years, and a fine up to $40,000. The mandatory minimum cannot be suspended and is not parole-eligible. These penalties apply regardless of the drug’s schedule, and the zones include school vehicles as well as school property.

Paraphernalia

Possessing drug paraphernalia with intent to use it for producing, storing, or consuming a controlled substance is a misdemeanor:¹¹

First offense: fine up to $500, no jail time
Subsequent offenses: up to 2 years in jail, a fine up to $2,000, or both

Fentanyl testing strips are excluded from the paraphernalia definition. Possessing or distributing them is not a criminal offense.

Cannabis Is Handled Separately

Maryland legalized recreational cannabis for adults 21 and older in July 2023, and marijuana no longer sits inside the traditional schedule-and-penalty structure for most practical purposes. Adults 21 and older can possess up to 1.5 ounces of flower, 12 grams of concentrate, or products containing up to 750 milligrams of THC without any penalty. That’s the “personal use amount.”¹²

Possessing more than the personal use amount but no more than 2.5 ounces is a civil offense with a fine up to $250, not a criminal conviction. Possessing more than 2.5 ounces is a criminal misdemeanor punishable by up to 6 months in jail and a $1,000 fine.¹ Smoking cannabis in public is a civil offense: up to $50 for a first violation, up to $150 for later ones. Anyone under 21 who possesses the personal use amount faces a civil fine up to $100; possession above that hits the same tiered penalties adults face.

Good Samaritan Protection During an Overdose

Maryland’s Good Samaritan Law shields both the caller and the person overdosing from prosecution for certain misdemeanors when someone seeks medical help. Evidence obtained solely because of that call cannot be used to arrest or prosecute anyone involved for possessing a controlled substance, possessing paraphernalia, or alcohol-related offenses involving minors.¹³

The protection also reaches people on pretrial release, probation, or parole: evidence discovered solely because they sought medical help cannot be used to establish a violation. The limits are important. It does not cover drug felonies like distribution, it only applies to people actively helping with the medical emergency, and it does not stop police from investigating or gathering evidence through other means.¹³
