What is Type 3 Cannabis? A Guide to High-CBD, Low-THC Hemp Flower
The Cannabis Type System Explained
The labels on cannabis products can read like a chemistry exam - THC percentages, CBD ratios, “full spectrum,” “Type 3.” The Type 1/2/3 system is how scientists and the modern cannabis industry classify varieties by their cannabinoid ratio, and understanding it changes how a person shops for high CBD low THC flower.
This classification traces back to early 1970s research that surveyed hundreds of cannabis varieties and identified distinct chemical profiles based on their THC-to-CBD ratios. A chemotaxonomic analysis published in the American Journal of Botany confirmed the system using genetic and chromatographic evidence across 157 accessions, establishing the three chemotypes as a reliable framework for classifying cannabis (Hillig & Mahlberg, 2004). More than two decades after that confirmation - and fifty years after the original discovery - the system still holds.
Type 1: High THC, Low CBD
This is what most people think of when they hear “cannabis” or “marijuana.” Type 1 varieties are bred to produce high levels of THC - the psychoactive compound responsible for the intoxicating “high.” CBD content is minimal. Most products sold at licensed dispensaries are Type 1. Effects include euphoria, altered perception, potential anxiety or paranoia at higher doses, and cognitive impairment.
Type 2: Balanced THC and CBD
Type 2 varieties produce meaningful amounts of both THC and CBD. The ratio varies - some lean toward THC, others toward CBD - but both cannabinoids are present in significant concentrations. Some medical cannabis programs favor Type 2 varieties for patients who want therapeutic effects without the full intensity of Type 1. This category is also where many “THCA hemp” products land, though their marketing often obscures this fact.
Type 3: High CBD, Low THC
This is hemp flower. Type 3 cannabis is bred to produce high levels of CBD - typically 10-20% - while keeping THC below 0.3% Delta-9 (the federal legal limit under the 2018 Farm Bill). The result is a product that looks, smells, and smokes like cannabis but does not produce intoxication. What people report is subtle: a calming of tension, a softening of physical discomfort, a quieting of mental noise.
ARC Farms grows exclusively Type 3 cannabis. Every strain tests below 0.3% Delta-9 THC. Every product is non-intoxicating by design. Browse ARC Farms’ Type 3 hemp flower strains to see what that looks like in practice.
Type 4: High CBG, Low THC and CBD
An emerging category. Type 4 varieties are bred for cannabigerol (CBG), sometimes called the “mother cannabinoid” because it is the precursor compound from which THC and CBD develop. Type 4 products are less common and less studied, but interest is growing.
Type 3 Hemp Flower: CBD Without Intoxication
The practical difference between Type 1 and Type 3 cannabis is not subtle. It is the difference between a product that alters consciousness and one that does not.
Type 3 hemp flower allows people to access the benefits associated with the cannabis plant - calm, physical ease, sleep support, stress reduction - without any of the effects that make Type 1 cannabis incompatible with daily functioning. A person can use Type 3 flower and then drive, work, parent, exercise, hold a conversation, make decisions. The result is calm, not compromise.
Several distinct groups of people are drawn to Type 3 for different reasons:
People who found THC to be too much. THC-induced anxiety and paranoia are common complaints, especially at the potency levels found in modern dispensary products. Type 3 flower removes the compound responsible for those effects while preserving the rest of the plant’s profile. For those looking to step back from THC, our guide covers using CBD flower during a tolerance break.
People who want the ritual without the impairment. Former cannabis users who miss the act of smoking - the grinding, rolling, inhaling, the pause in the day - but don’t want the cognitive effects. Type 3 flower preserves the ritual exactly while changing the destination. Former tobacco smokers find the same thing: read about CBD flower as a cigarette alternative.
People managing everyday stress, sleep, or discomfort. The wellness applications of CBD are the most common reason people seek out Type 3 hemp. A review of seven clinical trials, published in the Journal of Clinical Medicine, found that CBD supported a healthier stress response in all studies examined, working through the body’s own endocannabinoid system (Henson et al., 2021). Sleep support, anxiety management, and physical comfort are the use cases customers report most frequently.
People who work in drug-tested environments. While no full-spectrum hemp product can guarantee a passed drug test (trace THC is present), Type 3’s extremely low THC levels represent the lowest-THC option available in whole-flower form.
People in the sober-curious movement. Adults reducing or eliminating alcohol who want an evening ritual that creates real relaxation without impairment or next-day consequences.
Type 3 vs. THCA Flower: An Important Distinction
This is where the cannabis market gets confusing - and where being informed protects consumers.
Many products sold online as “hemp flower” are actually high-THCA varieties. THCA (tetrahydrocannabinolic acid) is the raw, unheated form of THC. In its raw state, THCA is non-intoxicating. But when flower is smoked or vaporized, heat converts THCA to THC - the psychoactive compound. A product with 20% THCA and 0.2% Delta-9 THC will pass a pre-sale compliance test (which measures Delta-9 only), but when lit, that 20% THCA converts to THC and produces a functional high.
This is a regulatory loophole, not a product category. Brands selling high-THCA flower are selling what is effectively marijuana under a legal technicality. The experience is intoxicating. The product will impair. And for people seeking the real benefits of CBD-dominant hemp, high-THCA flower is not what they’re looking for.
The science here is clear. Genetic research published in Genetics demonstrated that the THC-to-CBD ratio is controlled by a single gene locus: Type 3 hemp plants carry two copies of the CBD-producing allele and zero copies of the THC-producing allele. They are genetically incapable of producing intoxicating levels of THC (de Meijer et al., 2003). That genetic lock is what separates true Type 3 hemp from high-THCA products hiding behind a testing technicality.
How to tell the difference:
Check the Certificate of Analysis (COA). Look for the CBD percentage - it should be the dominant cannabinoid, typically 10-15% or higher. Look at THCA - it should be low (under 1%). If THCA is 15-25%, that product will produce a high when smoked, regardless of what the label says about “hemp.”
Look at the total THC calculation. Some COAs show “Total THC” which accounts for THCA conversion (Total THC = Delta-9 THC + (THCA x 0.877)). ARC Farms’ strains show Total THC ranging from 0.18% to 0.29% - consistently below the 0.3% federal threshold.
Consider the brand’s positioning. Brands that prominently feature strain names associated with high-THC cannabis (Wedding Cake, Gelato, OG Kush at 25% THCA) are selling intoxicating products. Brands that lead with CBD percentages, process transparency, and COA data are more likely to be selling genuine Type 3 hemp.
ARC Farms chose to stay Type 3 when the market incentivized the pivot to THCA. Many competitors made the switch because THCA products command higher prices and attract customers looking for a legal high. ARC Farms’ position is simple: the company was founded to grow non-intoxicating hemp, and that’s what it does. Not by technicality, but by design.
How to Identify Genuine Type 3 Hemp Flower
Modern cannabis taxonomy, reviewed in Cannabis and Cannabinoid Research, confirms that the difference between hemp and marijuana comes down to genetics - specifically, which enzyme pathway the plant’s DNA codes for: one that produces THC, or one that produces CBD (McPartland, 2018). With that understanding, here’s what to look for when buying hemp flower that is actually Type 3.
Published COAs from accredited labs. Every reputable Type 3 brand publishes Certificates of Analysis for their products. Look for the lab name, sample date, and a full cannabinoid panel. ARC Farms is tested by Motzz Laboratory Inc. in Phoenix, Arizona - an Arizona Department of Agriculture contract lab.
CBD as the dominant cannabinoid. In Type 3 flower, CBD (or CBDa, its acid precursor) should be the most abundant cannabinoid. ARC Farms’ strains range from 11.09% CBD (Strawberry Lemonade) to 14.42% CBD (Legendary OG).
A full cannabinoid profile. Quality Type 3 flower contains more than just CBD. Look for CBDa, CBG, CBGa, and other minor cannabinoids in the lab results. This “full spectrum” profile means the product delivers the plant’s complete cannabinoid range, not just isolated CBD.
Process transparency. Type 3 growers who are proud of their product will tell you how it was grown, dried, trimmed, and tested. Vague descriptions (“premium quality,” “top shelf,” “hand-selected”) without specific process details are a red flag in any part of the cannabis market.
ARC Farms: Type 3 CBD Flower From Tucson
ARC Farms Hemp grows five Type 3 strains in a climate-controlled light-deprivation greenhouse in Tucson, Arizona. The facility uses natural sunlight filtered through a controlled system, with temperature, humidity, and air exchange monitored by a centralized controller. Regenerative living soil, no synthetic salts, no pesticides, no growth regulators.
Five founders. Four generations of agricultural experience. A name - Arizona Regenerative Cannabis - that captures the commitment: Arizona-based, regenerative methods, cannabis done right.
Here’s what the COA data shows for every ARC Farms strain: Legendary OG (Indica, 14.42% CBD, 0.18% Total THC, earthy/pine/fuel/gassy aroma). Payton’s Strawberries (Hybrid, 13.55% CBD, 0.29% Total THC, berry/candy/creamy aroma). Daiquiri Factory (Sativa, 12.61% CBD, 0.26% Total THC, tropical/citrus/floral aroma). Strawberry Lemonade (Hybrid, 11.09% CBD, 0.22% Total THC, strawberry/lemon/berry aroma). Skunk Jam (cookie/candy/gas aroma, 0.19% Total THC).
Every strain falls below the 0.3% Total THC threshold - the result of growing varieties bred specifically for CBD dominance. This is high CBD low THC flower by design, not by technicality.
The flower is hang-dried in cold, dark rooms and hand-trimmed by the team. Small-batch production means inventory turns over quickly. When the jar opens, the trichomes are frosty, the aromas are rich, and the flower hasn’t been sitting on a shelf.
Not a Smoker? The Tincture Option
Not everyone who’s interested in Type 3 hemp wants to smoke it. ARC Farms makes two solventless tinctures that deliver the same full-spectrum cannabinoid profile without any inhalation. Both are made from ice water hash pressed into pure rosin - no chemical solvents, no additives, two ingredients each.
The MCT Tincture pairs pure rosin with C8 MCT oil for a neutral flavor. The Lemon Drop uses organic cold-pressed lemon olive oil for a subtle citrus note. Take 1 mL under the tongue, hold for thirty seconds, or add to tea or a mocktail. Effects arrive in fifteen to thirty minutes and last four to six hours.
Who Uses Type 3 Hemp Flower?
The people buying Type 3 hemp flower span a wide range of ages, lifestyles, and reasons.
People who smoke a small amount before bed because it helps quiet the mind enough to sleep. People who keep a jar on the counter and take a draw after work instead of pouring a drink. Former cannabis users who got tired of the anxiety and paranoia that came with high-THC products. Athletes who use it after training for physical recovery. People managing chronic discomfort who want something with fewer side effects than what the pharmacy offers. Parents who want to decompress after the kids are in bed without being impaired.
What they have in common is a preference for something that works without compromising how they function. Type 3 hemp flower is designed for exactly that.

Frequently Asked Questions
Does Type 3 hemp flower get a person high?
No. That is the defining characteristic of Type 3 cannabis - high CBD, very low THC, non-intoxicating. ARC Farms’ strains test between 0.11% and 0.20% Delta-9 THC. There is no high, no impairment, and no altered consciousness.
Is Type 3 hemp flower legal?
Yes. The 2018 Farm Bill legalized hemp containing less than 0.3% Delta-9 THC at the federal level. Most states permit the sale and possession of compliant hemp products.
What’s the difference between CBD flower and Type 3 cannabis?
They’re the same thing. “CBD flower,” “hemp flower,” “Type 3 CBD flower,” and “Type 3 cannabis” all describe cannabis varieties bred for high CBD and low THC. “Type 3” is the formal classification; “CBD flower” and “hemp flower” are the common consumer terms.
Is THCA the same as hemp?
No. High-THCA products may be sold as “hemp” for legal compliance, but they produce intoxicating effects when smoked because heat converts THCA to THC. Genuine hemp flower (Type 3) has low levels of both THC and THCA. Check the COA before buying.
Will Type 3 hemp show on a drug test?
Full-spectrum Type 3 products contain trace amounts of THC. Anyone concerned about drug testing should consult with their employer or testing facility before using any hemp product.
