Is Marijuana Legal in Kentucky? Medical Card, Limits, and Penalties

Marijuana is not fully legal in Kentucky. Recreational use remains a criminal offense, but the state’s medical cannabis program began operating in late 2025, so patients with qualifying conditions can now buy and possess cannabis through licensed dispensaries. Governor Andy Beshear signed Senate Bill 47 on March 31, 2023, making Kentucky one of the last states in the region to authorize medical use.¹

Recreational Possession Is Still a Crime

Possessing any amount of marijuana without a medical card is illegal. For less than eight ounces, you face up to 45 days in jail and a $250 fine. Holding eight ounces or more triggers a legal presumption that you intend to sell, which pushes the case into trafficking territory with much harsher consequences.

Paraphernalia is a separate charge. Possessing drug paraphernalia is a Class A misdemeanor, carrying up to 12 months in jail and a fine of up to $500.²

Who Qualifies for Medical Cannabis

To use cannabis legally in Kentucky, you need a written certification from a physician or advanced practice registered nurse and a state-issued registry card. You must be diagnosed with one of these conditions:³

Any type or form of cancer
Chronic, severe, or debilitating pain
Epilepsy or other intractable seizure disorders
Multiple sclerosis, muscle spasms, or spasticity
Chronic nausea or cyclical vomiting syndrome resistant to conventional treatment
Post-traumatic stress disorder

The Kentucky Center for Cannabis can add new qualifying conditions if scientific evidence supports it.³

Getting a Medical Cannabis Card

The practitioner writing your certification must be authorized to prescribe controlled substances, establish a genuine treatment relationship with you, confirm your diagnosis, review your prescription monitoring history for the prior 12 months, and discuss the risks and potential drug interactions of cannabis.⁴ Your first certification has to come from an in-person exam. Telehealth does not count for the initial visit.

With the certification in hand, you apply through the state’s patient and caregiver portal. The application fee is $25. Applicants with certain felony convictions are disqualified.⁵

What You Can Buy and Possess

Dispensaries sell edibles, oils, tinctures, vaporizer products, and raw plant material. Smoking is not permitted, and dispensaries cannot sell accessories used solely for smoking, including rolling papers. Home cultivation is prohibited under any circumstances.

Products are capped by THC content: raw flower at 35%, concentrates at 70%, and edibles at 10 milligrams of THC per serving.

Cardholders can keep up to a 30-day supply at home, which translates to 112 grams of raw plant material, 28 grams of concentrate, or 3,900 milligrams of THC in infused products. Away from home, you can carry up to a 10-day supply on your person.

Visiting From Another State

Kentucky recognizes out-of-state medical cannabis patients. If you hold a valid registry card from another state, you can buy and possess up to a 10-day supply here without a Kentucky card. Bring your out-of-state card, a separate government-issued photo ID, and documentation of your qualifying diagnosis to any licensed dispensary.⁵

That 10-day supply works out to 37.5 grams of raw plant material, 9.5 grams of concentrate, or 1,300 milligrams of THC in infused products.⁵

Hemp and CBD Products

Hemp is legal in Kentucky and treated separately from marijuana. State and federal law define hemp as cannabis with a Delta-9 THC concentration of no more than 0.3% on a dry weight basis. The 2018 Farm Bill removed hemp meeting that threshold from the federal Controlled Substances Act, and Kentucky runs its own regulated hemp program.⁶

Hemp-derived CBD products are generally legal to buy and use if they stay within the 0.3% Delta-9 THC limit. One catch: raw hemp flower is off-limits to regular consumers. Only licensed growers, processors, and handlers can possess or transport unprocessed hemp plant material, and possessing raw hemp without a license carries the same penalties as marijuana possession.

Products containing Delta-8 THC and similar hemp-derived cannabinoids are currently permitted if they stay within the Delta-9 THC limit. Federal legislation signed in late 2025 bans most synthetic and intoxicating hemp-derived THC products, with enforcement beginning in late 2026. The rules in this corner of the market are shifting, so check before you buy.

Cultivation and Trafficking Penalties

Growing marijuana without authorization is illegal regardless of plant count. Fewer than five plants is a Class A misdemeanor for a first offense, punishable by up to 12 months in jail and a fine of up to $500.⁷ Five or more plants is a Class D felony for a first offense and a Class C felony for subsequent offenses. Growing five or more plants also creates a legal presumption that you intended to sell.⁸

Trafficking penalties scale with weight:⁹

Less than 8 ounces: Class A misdemeanor for a first offense; Class D felony for a second or subsequent offense.
8 ounces to under 5 pounds: Class D felony for a first offense; Class C felony for a second or subsequent offense.
5 pounds or more: Class C felony for a first offense; Class B felony for a second or subsequent offense.

Because eight ounces triggers the intent-to-sell presumption, you can face trafficking charges without any direct proof of a sale.¹⁰

Driving After Using Cannabis

Driving under the influence of marijuana is a DUI in Kentucky, and a medical card is not a defense. Kentucky’s implied consent law means you have already agreed to submit to breath, blood, or urine testing simply by driving on state roads, and an officer with reasonable grounds to suspect impairment can require it.

A first DUI within a 10-year period carries a fine of $200 to $500, 48 hours to 30 days in jail, and a six-month license suspension. The suspension can drop to four months with an ignition interlock device. Aggravating factors like causing a serious accident or having a child passenger under 12 in the vehicle increase the minimum jail time.¹¹ Repeat offenses within 10 years escalate to felony-level charges with mandatory minimum sentences.

What the Card Does Not Protect

Your Job

The medical cannabis law explicitly does not shield patients from workplace consequences. Employers can keep zero-tolerance drug policies, prohibit cannabis on the premises, restrict cardholders from operating equipment they consider a safety concern, and test employees for cannabis use. The law creates no right to sue for wrongful termination or discrimination based on cardholder status.¹²

If you are fired for using medical cannabis at work, working while impaired, or testing positive in violation of your employment contract or company policy, you are ineligible for unemployment benefits.¹²

Your Housing

Landlords and property owners can prohibit the use, possession, transportation, and growing of medical cannabis on their property.¹² Medical cannabis use is not a protected class under Kentucky housing law. If your lease bans cannabis, that ban is enforceable. Read your lease before using at home.

Your Right to Buy a Gun

This one catches people off guard. Marijuana remains a Schedule I controlled substance under federal law, which prohibits any “unlawful user of or addicted to any controlled substance” from possessing firearms or ammunition.¹³ Federal law does not recognize state medical cannabis programs, so a registered Kentucky patient buying legally from a licensed dispensary is still an unlawful user under federal firearms law. The ATF’s Form 4473 asks directly about controlled substance use, and buying a gun while holding a medical card exposes you to federal prosecution.

Your Wallet

Neither private health insurance, government medical assistance programs, nor workers’ compensation is required to cover medical cannabis in Kentucky. Patients pay entirely out of pocket.

Clearing an Old Marijuana Conviction

Kentucky allows expungement of certain marijuana-related convictions. Class D felony marijuana cultivation charges are among the offenses eligible, provided the conviction did not involve a sexual offense, harm to a child, or death or serious bodily injury.¹⁴ Misdemeanor marijuana convictions are also generally eligible. Expungement removes the conviction from public records, which can matter for employment and housing applications. Talk to an attorney to confirm eligibility and handle the filing.
