Hemp vs. Cannabis: What’s the Difference?

Products containing THC and other cannabinoids have been legal to purchase in Virginia for years. But the availability and legality of THC-containing products made from hemp have changed significantly in Virginia recently.

Before April 2026, Virginians had 2 legal avenues for purchasing THC: 1) hemp-derived products and 2) medical marijuana products from state-authorized dispensaries. Products made from hemp have been widely available online and at vape shops, convenience stores, and even gas stations throughout Virginia. Recently, however, you’ve probably noticed products labeled full-spectrum CBD, Delta-8, THCA, or hemp THC are no longer available. All the while, Virginia’s licensed medical cannabis dispensaries continue to provide physician-recommended cannabis products for certified patients.

So what’s the difference?

Although hemp and cannabis come from the same plant species, they are produced and regulated very differently. Those differences affect everything from product quality and safety to legality and medical oversight. With these state-level changes and even more stringent nationwide federal changes expected soon, understanding these distinctions is more important than ever.

If you’re considering cannabinoid therapy for relief, knowing where your products come from—and how they’re regulated—can help you make safer, more informed decisions.

Hemp and Cannabis Are the Same Plant

Botanically, hemp and cannabis both belong to the Cannabis sativa species. The distinction is purely legal.

Federal law defines hemp as cannabis containing 0.3% Delta-9 THC or less by dry weight. Plants containing more than that amount are legally classified as cannabis (often referred to as marijuana under federal law).

Although the plants may look nearly identical, they are grown, in theory, for very different purposes.

Hemp is commonly cultivated for:

• CBD production
• Food products
• Hemp seed oil
• Clothing and textiles
• Paper
• Industrial materials
• Building products

Medical cannabis is cultivated for:

• Therapeutic THC
• CBD-rich formulations
• Balanced THC/CBD products
• Specific terpene profiles
• Minor cannabinoids such as CBG and CBN
• Consistent medical dosing

Today’s licensed medical cannabis products are carefully developed to provide predictable therapeutic effects for patients with chronic medical conditions.

Why Hemp Products Became So Popular

Hemp has been part of agriculture in the United States for over 250 years. The 2018 Farm Bill clarified and legalized hemp cultivation throughout the United States but, due to some inadequate language, a loophole in the bill inadvertently allowed the sudden, rapid expansion of hemp-derived intoxicating products. While the law was primarily intended to support agricultural hemp production, it created an unforeseen opportunity that dramatically expanded the market for hemp-derived intoxicating cannabinoids.

Manufacturers discovered they could extract CBD from hemp and chemically convert it into intoxicating compounds such as:

• Delta-8 THC
• Delta-9 THC
• Delta-10 THC
• THC-O
• HHC
• Other hemp-derived THC analogs

This meant that, by the letter of the law, hemp manufacturers were compliant. But by chemically converting the plant’s components, they could produce potent intoxicating products the law did not intend. This meant hemp products bypassed the regulation and safety standards established for regulated medical cannabis. Manufacturing safety, testing requirements, potency assurance, contamination oversight, advertising and packaging standards all went largely unregulated. These products quickly appeared in:

• Vape shops
• Smoke shops
• Convenience stores
• Gas stations
• Online retailers

Because these products were sold outside state-regulated medical cannabis programs, the hemp marketplace flourished with far less regulatory oversight. While this substantially reduced manufacturing costs, it also dramatically undermined consumer and public safety.

Medical Cannabis Is Produced Under Much Higher Standards

Virginia’s regulated medical cannabis program is designed entirely around patient safety.

Products sold through licensed Virginia dispensaries undergo rigorous quality control at every step before reaching patients. Testing typically includes:

• Cannabinoid potency
• Terpene analysis
• Heavy metals
• Pesticides
• Microbial contamination
• Residual solvents
• Manufacturing quality assurance

In addition, patients first receive an evaluation from a licensed healthcare practitioner to determine whether medical cannabis may be appropriate for their condition.

Licensed dispensaries also employ knowledgeable pharmacists and trained staff who can help patients understand dosing, product selection, and safe use.

This level of oversight simply isn’t available when purchasing hemp cannabinoid products from retail stores.

Hemp Products Are Regulated Very Differently

Many hemp manufacturers produce excellent products and voluntarily perform comprehensive laboratory testing. But this isn’t required, and many other manufacturers fall short, producing products with inconsistent quality and safety. Unlike Virginia’s medical cannabis program, there has historically been no single nationwide regulatory system governing intoxicating hemp-derived products.

Independent testing has shown that many commercially available hemp products may:

• Contain significantly different cannabinoid concentrations than listed
• Include unexpected unnatural cannabinoids
• Exceed legal THC limits
• Contain potentially dangerous contaminants
• Lack consistent quality control

For patients using cannabinoids to manage chronic pain, anxiety, sleep disorders, or neurological conditions, these inconsistencies can lead to unpredictable or even unsafe results.

Why Hemp Laws Are Changing

Virginia lawmakers, worried about the problems caused by the Farm Bill, in April 2026 strictly limited the availability of THC-containing hemp products. Federal lawmakers, equally concerned about the 2018 Farm Bill, also agreed to limit the nationwide unregulated hemp market starting in November 2026. The federal restrictions will be even more stringent than Virginia’s.

What are they concerned about? Let’s look. Many of these products have been marketed with:

• Minimal age verification
• Bright, youth-oriented packaging
• Inconsistent testing
• Limited manufacturing standards
• No physician involvement
• Inconsistent content and safety.

To address these concerns, recent and upcoming laws substantially narrow the definition of legal hemp and eliminate many hemp products. Virginia law has restricted hemp products to no more than 2 mg of THC per container. Federally, new prohibitions on synthetic cannabinoids take effect in November 2026, with further restrictions on naturally occurring cannabinoids slated for December 2026.

These changes are expected to prohibit most intoxicating hemp-derived THC products currently sold outside regulated cannabis programs while preserving traditional industrial hemp and many non-intoxicating CBD products. The goal is to close the loophole that allowed psychoactive hemp products to proliferate with limited oversight.

Which Products Will Disappear?

When the federal changes take effect, consumers across the country may see many familiar products disappear, including:

• Delta-8 THC gummies
• Delta-8 vape cartridges
• Delta-9 products
• Delta-10 products
• THCA flower marketed as hemp
• Hemp-derived THC beverages
• Many intoxicating hemp extracts sold online

For consumers in Virginia, many of these restrictions have already taken effect, but will become even more extensive. Businesses throughout the hemp industry are already preparing for these regulatory changes.

Why Virginia Medical Cannabis Patients Are Different

These Virginia and federal hemp restrictions do not affect Virginia’s licensed medical cannabis program.

Patients who receive a Virginia medical cannabis certification can continue obtaining THC products through state-authorized medical dispensaries that operate under strict pharmaceutical-style regulations and ensure patient safety.

Benefits include:

• Physician guidance
• Laboratory-tested products
• Consistent dosing
• Professional dispensary counseling
• Reliable manufacturing standards
• Legal access under Virginia law

For patients, this provides greater confidence that they know exactly what they are purchasing.

Should You Choose Hemp or Medical Cannabis?

The answer depends on your goals.

If you’re simply interested in wellness products such as hemp seed oil or non-intoxicating CBD, then compliant hemp products may still be appropriate.

However, if you’re treating chronic pain, arthritis, PTSD, cancer symptoms, multiple sclerosis, insomnia, neuropathy, or another qualifying medical condition, THC-containing medical cannabis offers several important advantages:

• Better product consistency
• Comprehensive laboratory testing
• Healthcare provider supervision
• Professional guidance on dosing
• Access to a wider range of therapeutic formulations

The Bottom Line

Although hemp and cannabis come from the same plant species, they exist in two very different regulatory worlds.

Hemp products became widely available because of the 2018 Farm Bill, but the rapid unintended growth of intoxicating hemp-derived cannabinoids has prompted Virginia and federal lawmakers to tighten regulations. Many Delta-8, THCA, and similar products are no longer legally available outside regulated cannabis programs.

Virginia’s medical cannabis program continues to provide patients with carefully tested products, physician oversight, and licensed dispensaries dedicated to patient safety.

For individuals seeking consistent, high-quality cannabinoid therapy, obtaining products through Virginia’s regulated medical cannabis program remains one of the safest and most reliable options.
