Kentucky Medical Cannabis Products & Limits

Last verified: April 2026

Allowed Product Forms

Kentucky's medical cannabis program permits the following product forms for registered patients:

• Raw plant material (flower) — for vaporization only
• Oils and tinctures — sublingual or oral administration
• Edibles — infused food and beverage products
• Topicals — creams, lotions, balms, and patches
• Vape cartridges — must be 21 or older (age restriction beyond the patient minimum)
• Concentrates — wax, shatter, rosin, and other concentrated forms

Smoking Is Prohibited

Kentucky law explicitly prohibits smoking cannabis. Flower may only be consumed through vaporization — a device that heats the plant material to a temperature below combustion, releasing cannabinoids without producing smoke. This distinction was a key compromise during SB 47's passage, as legislators wanted to avoid the health risks associated with combustion.

Patients who smoke cannabis instead of vaporizing it are technically violating the terms of the medical program and could lose their patient protections. Dispensaries sell vaporizer devices approved for use with raw plant material.

THC Caps and Supply Limits

Understanding the 30-Day Supply

Kentucky uses a 30-day supply system with an important timing restriction: you may purchase your full 30-day supply within a 25-day period. This means you cannot stockpile by purchasing a new supply every day. The dispensary's point-of-sale system tracks purchases across all locations to prevent exceeding the limit.

Outside the Home

When transporting medical cannabis outside your home, you may carry a 10-day supply in the original dispensary container. Products must remain in their labeled packaging with the dispensary seal intact. Loose cannabis or products in non-original containers may result in criminal charges even for registered patients.

THC Caps Explained

Flower: 35% THC Maximum

Raw plant material sold at Kentucky dispensaries cannot exceed 35% total THC by weight. Most cannabis flower sold in legal markets ranges from 15–30% THC, so this cap is unlikely to restrict most available strains. Very high-THC exotic strains that push above 35% would not be available in Kentucky.

Concentrates: 70% THC Maximum

Concentrated cannabis products — including wax, shatter, live rosin, and distillate — are capped at 70% THC. Many concentrates in other states' markets exceed this level (some distillates reach 90%+), so Kentucky patients will see a more restricted selection in this category.

Edibles: 10 mg Per Serving

Each individual serving of an edible product cannot exceed 10 mg of THC. This is the most common per-serving limit across U.S. medical and recreational programs. Multi-serving packages are allowed but must be clearly divided into 10 mg portions with appropriate labeling.

No Home Cultivation

Home cultivation is prohibited for all purposes in Kentucky, including for registered medical patients. This places Kentucky among the most restrictive medical programs nationally. Patients in neighboring states like Ohio (6 plants for recreational) and Missouri (6 plants) have home-grow options that Kentucky patients do not.

Sales Tax

Medical cannabis products in Kentucky are subject to a 6% state sales tax. Unlike some states that impose additional excise taxes on cannabis (Colorado charges an additional 15% excise tax on recreational), Kentucky applies only the standard sales tax rate. This helps keep prices manageable for patients, though the cumulative cost of doctor visits, card fees, and product prices can still be significant.

Product Labeling Requirements

All medical cannabis products must include:

• THC and CBD content per serving and per package
• Batch number and testing laboratory identification
• Cultivator and processor identification
• Expiration date
• Warning statements required by the Office of Medical Cannabis
• Universal cannabis symbol
