Do You Need a Medical Card to Buy THCa in North Carolina?
No. You do not need a medical card, prescription, doctor's recommendation, or any special authorization to buy THCa products in North Carolina. There's no medical marijuana program in NC to get a card from in the first place.
THCa is sold as a legal hemp product at dispensaries across the Triangle. You can walk in, browse the selection, and buy it — same as you'd buy CBD oil or any other hemp product. Here's why.
TL;DR: NC has no medical marijuana program, so there are no medical cards to get. THCa products are legal hemp under the 2018 Farm Bill and NC SB 455 because pre-decarboxylation testing counts only Delta-9 THC, not THCa. No age requirement exists in state law (21+ is voluntary retailer policy). This changes in November 2026 when P.L. 119-37 switches to total THC testing, which would effectively ban THCa flower. NC's hemp industry supports ~9,000 jobs and up to $1.1 billion in sales (WFAE, 2026).
Why No Medical Card Is Needed
Two reasons, both simple:
1. NC doesn't have a medical marijuana program. The Compassionate Care Act (SB 711) passed the NC Senate in 2023 but died in the House and was never enacted. As of February 2026, there is no medical cannabis licensing system, no patient registry, and no medical card to apply for.
2. THCa is classified as legal hemp, not marijuana. Under the 2018 Farm Bill and NC Session Law 2022-32 (SB 455), hemp is Cannabis sativa L. with no more than 0.3% Delta-9 THC by dry weight. The critical detail: current testing measures only Delta-9 THC in its raw, unheated state. THCa is a different molecule (it has an extra carboxyl group), so it's not counted toward that 0.3% limit.
That means THCa flower with 25% THCa and 0.15% Delta-9 THC is legal hemp — even though smoking it produces effects indistinguishable from marijuana.
What Exactly Is THCa?
THCa (tetrahydrocannabinolic acid) is the raw, naturally occurring precursor to Delta-9 THC. Every cannabis plant — hemp and marijuana alike — produces THCa as it grows. In its raw form, THCa is non-psychoactive because the carboxyl group prevents it from binding to CB1 receptors in your brain.
When you apply heat (smoking, vaping, cooking), a process called decarboxylation removes that carboxyl group and converts THCa into Delta-9 THC — the same psychoactive compound found in marijuana.
The conversion factor is 0.877 — meaning 1mg of THCa yields about 0.877mg of Delta-9 THC when heated (Confidence Analytics). A single gram of 25% THCa flower produces roughly 219mg of total THC. That's why THCa flower is the most popular product at Triangle dispensaries — and the biggest gray area in hemp law.
THCa Flower: What You're Actually Buying
THCa flower is the product category that drives this entire conversation. It looks, smells, and — when smoked — feels like marijuana. The NC State Bureau of Investigation has acknowledged that hemp and marijuana are "indistinguishable by sight and smell."
Here's what typical THCa flower looks like on paper:
- THCa content: 20-30% (comparable to mid-to-high-grade marijuana)
- Delta-9 THC content: 0.1-0.3% (under the legal limit in raw form)
- Total THC when smoked: 175-264mg per gram (after decarboxylation)
- Effects: Equivalent to marijuana when heated
The practical takeaway: THCa flower delivers marijuana-strength effects through a product classified as legal hemp. No card, no prescription, no qualifying condition required. You walk into a dispensary and buy it.
What About Age Requirements?
Here's something that surprises most people: North Carolina has no state law setting a minimum age to buy THCa or any hemp-derived product. Governor Stein confirmed this as a core issue in June 2025, stating that "today all across North Carolina, there are unregulated intoxicating THC products available for purchase: just walk into any vape shop" (Governor's Office, 2025).
The 21+ age check you encounter at reputable dispensaries is voluntary store policy, not state law. It's actually one of the clearest signals that you're buying from a responsible retailer.
House Bill 607, filed in March 2025, would change this by establishing a mandatory 21+ age requirement with ALE enforcement, along with edible potency caps (10mg/serving, 100mg/package) and COA requirements from accredited labs (NC General Assembly).
How NC Compares to States with Medical Programs
In states like Florida, Maryland, or Ohio, buying cannabis products requires:
- A qualifying medical condition (chronic pain, PTSD, cancer, etc.)
- A doctor's recommendation or certification
- A state-issued medical card ($50-$300+ per year in fees)
- Purchasing only from state-licensed dispensaries
- Possession limits and renewal requirements
In North Carolina, buying THCa requires:
- Walking into a dispensary
- That's it
This is because NC classifies THCa as hemp, not as medical cannabis. There's no medical program to opt into, no conditions to qualify for, and no cards to carry. The product sits on the shelf next to CBD tinctures and Delta-8 vapes.
The irony is that some consumers in medical-card states face more restrictions buying THCa than NC consumers do — because those states regulate all THC-containing products, including hemp-derived ones.
Why COAs Matter More Without Medical Oversight
Without a state medical program overseeing production and testing, the burden of quality assurance falls on consumers and retailers. This is where Certificates of Analysis (COAs) become essential.
A proper COA from a third-party accredited lab should show:
- Cannabinoid potency: Confirms the THCa percentage and verifies Delta-9 THC is under 0.3%
- Pesticide screening: Detects harmful chemicals used during cultivation
- Heavy metals testing: Checks for lead, arsenic, mercury, and cadmium
- Microbial analysis: Tests for mold, bacteria, and yeast
- Residual solvents: Relevant for concentrates and extracts
- Mycotoxin testing: Screens for toxic fungal compounds
If a dispensary can't show you a COA for a THCa product, don't buy it. That test is the only thing standing between you and an untested product in an unregulated market.
The FDA has documented 104 adverse event reports related to Delta-8 THC products alone, with 55% requiring emergency room visits (FDA, 2022). While those numbers are specific to Delta-8, they illustrate the risks of consuming unregulated cannabinoid products without proper testing.

The November 2026 Deadline
The federal Continuing Resolution (P.L. 119-37), signed November 12, 2025, changes everything for THCa. The new law measures total THC — including THCa, Delta-8, Delta-9, and all other THC variants — instead of Delta-9 alone. The limits: 0.3% total THC by dry weight and 0.4mg per finished container (Perkins Coie, 2025).
For THCa flower, the math is devastating. A gram of 25% THCa flower contains approximately 219mg of total THC (after applying the 0.877 conversion factor). The new federal cap is 0.4mg per container. That's 547 times over the limit.
UNC School of Government professor Phil Dixon noted in January 2026 that NC state law hasn't changed and hemp products "remain legal as a matter of state law." But once the federal ban kicks in, state-federal conflict creates real enforcement uncertainty (UNC SOG, 2026).
Drug Testing: A Critical Warning
Standard drug tests cannot distinguish between THCa-derived THC and marijuana-derived THC. When you smoke THCa flower, your body metabolizes it into THC-COOH — the same metabolite produced by marijuana. Standard immunoassay tests detect this at a cutoff of 50 ng/mL.
Detection windows depend on how often you use:
- Occasional (1-3 times/week): 3-7 days
- Moderate (4+ times/week): 10-15 days
- Daily/chronic: 30+ days
If your employer drug tests, using legal THCa products creates the exact same risk as using marijuana. There is no commercially available test that can tell the difference. This applies to Delta-8, Delta-9 gummies, and any other THC-containing hemp product.

Frequently Asked Questions
Does North Carolina have medical marijuana?
No. The Compassionate Care Act (SB 711) passed the NC Senate in 2023 but died in the House. As of February 2026, NC has no medical marijuana program, no patient cards, and no qualifying conditions list. Governor Stein's Advisory Council on Cannabis is expected to issue preliminary recommendations by March 2026, but no legislation has been enacted.
Is THCa legal in North Carolina?
Yes. THCa products are legal hemp under the 2018 Farm Bill and NC Session Law 2022-32 (SB 455). Current testing measures only Delta-9 THC in its raw state, and THCa is not Delta-9 THC until it's heated. For the full legal breakdown, see our guide on THCa legality in NC.
Will THCa get me high?
In raw form, no — THCa is non-psychoactive. But when heated (smoking, vaping, cooking), THCa converts to Delta-9 THC through decarboxylation and produces psychoactive effects equivalent to marijuana. THCa flower with 25% THCa will produce effects comparable to mid-to-high-grade marijuana when smoked.
How old do you have to be to buy THCa in NC?
There is currently no state law setting a minimum age. The 21+ policy at reputable dispensaries is voluntary. HB 607 proposes a mandatory 21+ requirement that would take effect July 2026 if passed. In the meantime, a store checking your ID is a sign you're buying from a responsible retailer.
Can I grow my own THCa hemp in North Carolina?
Growing hemp in NC requires a license from the NC Department of Agriculture. Personal cultivation of hemp is not permitted without a grower's license. This is different from some states that allow personal cultivation. Possession of a cannabis plant exceeding 0.3% Delta-9 THC would be classified as marijuana cultivation, which is a felony in NC.
Is THCa the same as THC?
THCa (tetrahydrocannabinolic acid) is the chemical precursor to THC. They're closely related but not identical. THCa has an extra carboxyl group that prevents it from binding to CB1 receptors, so it's non-psychoactive in raw form. Heat removes that group (decarboxylation), converting THCa to Delta-9 THC at a ratio of 0.877. The legal distinction matters: THCa is not counted as THC under current testing standards, which is why hemp flower can legally contain high THCa while staying under the 0.3% Delta-9 limit.
The Bottom Line
You don't need a medical card to buy THCa in North Carolina — because there's no medical program and THCa is classified as legal hemp. No prescription, no qualifying condition, no card fees. Just walk into a reputable dispensary and ask.
But buy smart. Look for COAs, stick to established retailers, and understand that what you're consuming will show up on a drug test exactly like marijuana. The legal classification is "hemp." The chemical reality, once heated, is THC.
And keep an eye on November 2026. The federal total-THC standard will fundamentally change what's available, and NC's own regulatory framework is still being written.
