Is Cannabis Legal in Delaware? Limits, Use, and Penalties

Yes, cannabis is legal in Delaware for adults 21 and older, and licensed retail sales began August 1, 2025. You can possess up to one ounce of flower, buy from state-licensed dispensaries with a government photo ID, and consume in a private residence. You cannot grow your own plants for recreational use, cannot use cannabis in public, and cannot carry it across state lines. Medical patients registered with the state get higher possession limits, a tax exemption, and employment protections that recreational users do not have.

What Adults 21 and Older Can Possess

Delaware legalized recreational cannabis in April 2023, and licensed retail sales opened on August 1, 2025. If you are 21 or older, you can legally possess:

  • Up to one ounce of cannabis flower
  • Up to 12 grams of concentrate
  • Cannabis products containing up to 750 milligrams of Delta-9 THC

You can give cannabis to another adult within those limits as long as no money or anything of value changes hands. To buy from a dispensary, you need a valid government-issued photo ID proving you are at least 21, and stores cannot sell more than a personal use quantity in a single transaction.1Justia. Delaware Code Title 4 1332 – Retail Marijuana Store Licenses

Home cultivation is not allowed for recreational users. Unlike many other legalization states, Delaware prohibits growing your own plants unless you qualify under the medical program, so all legal supply runs through licensed retailers.

Where You Can Legally Use It

Consumption is limited almost entirely to private residences. Public consumption is a misdemeanor punishable by up to five days in jail, a fine of up to $200, or both. The prohibited zones are broader than most people expect: anywhere within 10 feet of a sidewalk, street, parking lot, park, playground, store, or restaurant, and within 10 feet of entrances, exits, windows, or ventilation intakes of any building. Using cannabis in a moving vehicle is also illegal.

Property owners and employers can prohibit cannabis on their premises, but residential landlords have narrower authority than most tenants realize. Under Delaware’s Marijuana Control Act, a landlord of a residential rental can only prohibit possession or non-smoked consumption (like edibles) in limited situations: when the landlord lives in the building and rents no more than three rooms, when the housing is incidental to institutional care or education (dormitories, nursing facilities, prisons), or when federal law or funding requires it.2Delaware Code Online. Delaware Code Title 4 Chapter 13 Subchapter I – Section 1307 Private Property Rights In practice, most apartment landlords can ban smoking cannabis but cannot ban tenants from possessing it or eating edibles inside their unit.

Transporting Cannabis

You can carry a personal use quantity in your vehicle, but it must be in a closed container or otherwise not readily accessible to anyone inside.3Delaware General Assembly. House Bill 1 – Delaware Marijuana Control Act – Section 4764A Think of it the way you would an open-container rule for alcohol: sealed and out of reach.

Do not cross state lines with any cannabis product. Marijuana remains illegal under federal law, and transporting it between states is a federal offense regardless of whether both states have legalized. The Office of the Marijuana Commissioner states plainly that you may not carry or transport marijuana over state lines, and mailing cannabis in or out of Delaware is also illegal.4Office of the Marijuana Commissioner. Frequently Asked Questions That applies equally to medical and recreational products.

Tax on Recreational Purchases

Delaware imposes a 15% retail marijuana tax on all recreational cannabis sales, calculated on the retail sales price, on top of any other applicable taxes.5Delaware Division of Revenue. Marijuana Establishments and Retail Tax FAQs If you hold a valid medical marijuana registry card and present it at the time of purchase, you are exempt from the 15% retail tax. For regular users, that exemption alone can make keeping a medical card worthwhile even now that recreational sales are open.

The Medical Cannabis Program

Delaware’s medical marijuana program dates to 2011 under the Delaware Medical Marijuana Act.6Delaware General Assembly. Senate Bill 17 To qualify, you must be a Delaware resident with a certification from a Delaware-licensed healthcare practitioner. Patients under 18 can qualify, but the certifying physician must be a qualifying pediatric specialist.7Delaware Code Online. Delaware Code Title 16 Chapter 49A – The Delaware Medical Marijuana Act

As of July 1, 2024, House Bill 285 removed the old requirement that patients have a specific “debilitating medical condition” from a fixed list. Healthcare practitioners can now certify any patient with a diagnosed medical condition they believe would benefit from cannabis.8Office of the Marijuana Commissioner. Medical Marijuana Program – Updates Card fees are $50 for one year, $75 for two years, or $100 for three years.

Registry cardholders can possess up to six ounces of usable cannabis at any time. Licensed dispensaries can dispense up to three ounces to a patient within any 14-day period.7Delaware Code Online. Delaware Code Title 16 Chapter 49A – The Delaware Medical Marijuana Act

Workplace Protections for Cardholders

Registered medical patients get employment protections recreational users do not. An employer cannot discriminate against you in hiring, firing, or any terms of employment based on your cardholder status, and cannot penalize you solely for testing positive for marijuana metabolites, unless you were actually using, possessing, or impaired by cannabis on the employer’s premises or during work hours. The mere presence of metabolites in your system does not count as being under the influence, which matters because metabolites can linger for days.9Delaware Code Online. Delaware Code Title 16 Chapter 49A – The Delaware Medical Marijuana Act – Section 4907A

The protections have limits. Employers can still bar consumption at work and discipline workers who show up impaired. There is also a federal carve-out: if complying with the anti-discrimination rule would cause an employer to lose federal funding or licensing, the employer is exempt. Landlords and schools face parallel rules and cannot refuse to lease to or enroll someone solely because they are a registered patient or caregiver, unless doing so would jeopardize federal benefits.10Delaware Code Online.

Where Legal Turns Into Illegal

Going Over the Possession Limit

Possessing more than one ounce but less than 175 grams is an unclassified misdemeanor, carrying up to three months in jail and a $575 fine.11Justia. Delaware Code Title 16 4764 – Possession of Marijuana At 175 grams and above, possession becomes a felony under the Uniform Controlled Substances Act, with sentences scaled by quantity tiers.12Delaware Code Online. Delaware Code Title 16 Chapter 47 Subchapter IV – Uniform Controlled Substances Act

Selling Without a License

Selling, growing, or manufacturing cannabis without a state license is a felony. Casual transfers between adults within the possession limits are legal, but as soon as compensation enters the picture the activity becomes felony distribution under the Uniform Controlled Substances Act, with penalties that scale by quantity.12Delaware Code Online. Delaware Code Title 16 Chapter 47 Subchapter IV – Uniform Controlled Substances Act

Driving Under the Influence

Cannabis DUI carries the same statutory penalties as alcohol DUI. A first offense brings a fine of $500 to $1,500, up to 12 months in jail (which the court can suspend), and mandatory installation of an ignition interlock device.13Justia. Delaware Code Title 21 4177 – Driving a Vehicle While Under the Influence The court will also order an alcohol and drug evaluation with a mandatory treatment or education program. Repeat offenses bring mandatory minimum jail time and longer license revocations.

Under 21

Anyone under 21 who possesses, uses, or consumes a personal use quantity of cannabis faces escalating consequences. A first violation is a $100 civil penalty. A second is between $200 and $500. A third or later violation becomes an unclassified misdemeanor with a $100 fine.11Justia. Delaware Code Title 16 4764 – Possession of Marijuana That third-offense jump from civil to criminal is the trap most families don’t see coming.

Expungement of Old Convictions

Delaware’s legalization law includes a mandatory expungement provision. Under Section 4770, anyone convicted of marijuana possession or cannabis-related drug paraphernalia offenses is eligible for expungement, as long as they have no violent felony convictions.14Delaware General Assembly. House Bill 150 – Section 4770 Expungement Eligibility The expungement order clears both the arrest record and the conviction. If you have an old possession charge on your record, it is worth checking whether you already qualify.
