Hemp vs Marijuana Defense in Kentucky

The Hemp vs. Marijuana Distinction in Kentucky Criminal Cases

Since the federal 2018 Farm Bill legalized hemp, Kentucky has developed a significant hemp industry. However, hemp and marijuana come from the same plant species (Cannabis sativa), and they can be difficult to distinguish visually, by smell, or even by some laboratory tests. This creates complex issues in Kentucky marijuana prosecutions. Clark + Harris has developed expertise in hemp vs. marijuana defense and represents clients facing marijuana charges in Lexington, Louisville, and throughout Kentucky.

The Legal Difference Between Hemp and Marijuana

Under federal and Kentucky law, the distinction between hemp and marijuana depends solely on delta-9 THC content. Hemp is cannabis with delta-9 THC concentration of 0.3% or less on a dry weight basis, legal under federal and Kentucky law when properly cultivated and processed. Marijuana is cannabis with delta-9 THC concentration exceeding 0.3%, illegal under Kentucky law except for limited medical purposes.

This means that visually identical plant material, with identical odor, can be either legal hemp or illegal marijuana depending on THC content. Testing is the only reliable way to distinguish between them.

Kentucky Hemp Program

Kentucky has a substantial hemp industry regulated by the Kentucky Department of Agriculture under KRS Chapter 260. Licensed hemp producers, processors, and retailers legally cultivate, process, and sell hemp products. Hemp-derived CBD products are widely available at retail stores throughout Kentucky.

The existence of a legal hemp industry creates significant challenges for marijuana prosecutions. Law enforcement may encounter cannabis material that is actually legal hemp, and failing to test properly can lead to wrongful charges.

Marijuana Prosecution in Kentucky

Despite the legal hemp industry, marijuana possession and trafficking remain criminal offenses in Kentucky. Possession of marijuana less than 8 ounces under KRS 218A.1422 is a Class B misdemeanor carrying up to 45 days jail and $250 fine. Trafficking in marijuana less than 8 ounces under KRS 218A.1421 is a Class A misdemeanor carrying up to 12 months jail. Trafficking 8 ounces to 5 pounds is a Class D felony carrying 1-5 years prison. Trafficking 5 pounds or more is a Class C felony carrying 5-10 years prison. Cultivation is prosecuted under KRS 218A.1423 based on number of plants.

Hemp Defense Strategies

Testing Requirements: To prove a marijuana case, the prosecution must establish that the substance contained more than 0.3% delta-9 THC. Many crime labs can identify cannabis but cannot quantify THC levels. If testing fails to establish THC quantity above the legal threshold, the prosecution cannot distinguish marijuana from legal hemp.

Lab Test Validity: We challenge the scientific validity of testing methods. Some field tests cannot distinguish hemp from marijuana at all, and even laboratory testing must follow proper protocols to produce reliable results.

Chain of Custody: Proper chain of custody is essential for test results to be admissible. We scrutinize chain of custody documentation for any gaps or irregularities.

Expert Testimony: We retain cannabis testing experts to review prosecution evidence and provide independent analysis. Expert testimony can be crucial in cases where the hemp/marijuana distinction is central.

Legal Hemp Source: Some clients possess cannabis material that was obtained as legal hemp. Documentation of legal purchase or cultivation can provide complete defenses to marijuana charges.

Smell Challenges: Historically, the smell of marijuana provided probable cause for searches in Kentucky. However, with legal hemp widely available, the smell of cannabis alone is increasingly insufficient to establish probable cause.

Probable Cause and Hemp

The legalization of hemp has changed the probable cause analysis in Kentucky. When cannabis odor could come from either legal hemp or illegal marijuana, the odor itself may not establish probable cause to search. Kentucky courts continue to develop this area of the law, and successful challenges to smell-based searches can result in suppression of evidence.

Medical Marijuana in Kentucky

Kentucky has enacted a limited medical marijuana program, though the program is not yet fully operational. When the program is implemented, patients with qualifying conditions will be able to legally use medical marijuana. Until then, possession of marijuana — even by patients with medical conditions — remains illegal under Kentucky law (though CBD and hemp products are legal).

Delta-8 and Other Cannabinoids

Kentucky has taken various positions on cannabinoids like delta-8 THC, delta-10 THC, and other derivative compounds. Some of these substances, though psychoactive, have been legally sold in Kentucky. However, the legal status continues to evolve, and careful analysis is needed for cases involving these compounds.

Alternative Resolutions for Marijuana Cases

For many marijuana cases, alternatives to conviction may be available. First-offense marijuana possession cases often qualify for pretrial diversion under KRS 533.250. Under KRS 218A.14151, some drug possession cases are eligible for deferred prosecution. First-offense marijuana cases may qualify for conditional discharge.
