Growing weed in Delaware at home is illegal, whether you have a medical marijuana card or not. Delaware legalized recreational possession for adults 21 and older in April 2023 through House Bill 1 and House Bill 2, and the state’s medical marijuana program has operated since 2011, but neither law allows personal cultivation. All cannabis has to come from a state-licensed facility, and putting even one plant in the ground or under a light at home can bring a felony charge.
Illegal for Everyone, Including Medical Patients
Section 4764A of Title 16 lists the marijuana activities that are legal for adults 21 and older, such as possessing and sharing small amounts. Growing cannabis without a state-issued license is not on that list and remains a crime.1Justia Law. Delaware Code Title 16 Section 4764A – Legal Marijuana-Related Activity The Delaware Office of the Marijuana Commissioner says the same thing in plain terms: home cultivation is prohibited.2Office of the Marijuana Commissioner. Adult-Use
The ban applies to medical patients too. The Delaware Medical Marijuana Act, Title 16, Chapter 49A, does not give patients or their designated caregivers any right to grow their own plants. Patients must get their medicine from a licensed compassion center.3Delaware Code Online. Delaware Code Title 16 Chapter 49A – The Delaware Medical Marijuana Act
No carve-out exists for a single plant, an indoor tent, a locked closet, or any other setup. If you don’t hold a commercial cultivation license from the state, growing cannabis is a criminal offense no matter the circumstances.
Felony Penalties by Weight
Unlicensed cultivation is prosecuted under the Uniform Controlled Substances Act (Title 16, Chapter 47) as manufacturing a controlled substance. The charge level depends on the weight of cannabis involved, not on whether you intended to sell it:
- Below Tier 2 (under 1,500 grams): Class D felony, carrying up to eight years in prison under Delaware’s sentencing framework.4Delaware Code Online. Delaware Code Title 16 Chapter 47 Subchapter IV – Section 4754
- Tier 2 (1,500 grams or more): Class C felony, up to 15 years in prison.5Delaware Code Online. Delaware Code Title 16 Chapter 47 Subchapter IV – Section 4753
- Tier 3 (5,000 grams or more): Class B felony, 2 to 25 years in prison.6Delaware Code Online. Delaware Code Title 16 Chapter 47 Subchapter IV – Section 4752
1,500 grams is about 3.3 pounds. A modest indoor setup with a few mature plants can produce enough over one cycle to land in Tier 2 territory. The manufacturing statute does not treat personal-use growing more leniently than growing for sale; the question is simply how much cannabis is present.
If aggravating factors accompany a Tier 2 quantity, the charge can be elevated to a Class B felony, the same level as Tier 3.6Delaware Code Online. Delaware Code Title 16 Chapter 47 Subchapter IV – Section 4752 Aggravating factors under Delaware law include things like prior convictions and other circumstances the statute spells out. Even a small home grow puts a felony record on the table.
What You Can Legally Do Instead
Since you can’t grow at home, legal cannabis in Delaware has to be bought. Delaware’s recreational retail market opened on August 1, 2025, when 12 existing medical dispensaries began selling adult-use products, with more retail, cultivation, and manufacturing licenses being issued by the Office of the Marijuana Commissioner.2Office of the Marijuana Commissioner. Adult-Use To buy recreational cannabis you must be 21 or older and show valid ID. No medical card is required. Medical patients continue to use their existing compassion centers.
Possession Limits for Adults 21 and Older
House Bill 1 defines the “personal use quantity” an adult can possess without penalty:
- Leaf marijuana: one ounce (28 grams) or less of dried flower
- Concentrated cannabis: 12 grams or less
- Cannabis products: items containing 750 milligrams or less of delta-9 THC
Possessing, using, purchasing, or transporting amounts within these limits carries no civil or criminal penalty.7Delaware General Assembly. House Bill 11Justia Law. Delaware Code Title 16 Section 4764A – Legal Marijuana-Related Activity Registered medical patients can purchase up to three ounces of usable cannabis every 14 days, for a total of six ounces per month.8Office of the Marijuana Commissioner. FAQs
Sharing, Not Selling
Adults 21 and older can give a personal use quantity or less to another adult as a genuine gift. The law prohibits sharing that comes with a reciprocal transaction, is advertised in connection with a sale, or is contingent on buying something else.1Justia Law. Delaware Code Title 16 Section 4764A – Legal Marijuana-Related Activity A “gift” tied to any other purchase is a sale, and unlicensed sales are still a crime.
Where You Can and Can’t Use It
Consuming cannabis in any area accessible to the public is still illegal, and so is consuming in a moving vehicle. Both are criminal offenses under the same chapter that legalized personal possession.1Justia Law. Delaware Code Title 16 Section 4764A – Legal Marijuana-Related Activity Driving under the influence of cannabis remains illegal.2Office of the Marijuana Commissioner. Adult-Use If you transport cannabis in a vehicle, it must be in a closed container or otherwise not readily accessible to anyone inside.
If you want to grow cannabis legally in Delaware, the only path is a commercial cultivation license through the Office of the Marijuana Commissioner. Anything else, no matter how small, is manufacturing under the controlled substances statute.
