THCp Flower: What It Is, How It's Made, and What You Need to Know
Quick Answer: THCp flower is hemp-derived cannabis flower that has been infused or coated with THCp (tetrahydrocannabiphorol), a rare, highly potent cannabinoid. Unlike traditional THC flower, THCp flower starts with compliant hemp and gains its potency through post-harvest processing that adds concentrated THCp extract to the plant material.
THCp flower is one of the strongest hemp products on the market, and it is very different from regular THC bud. This guide explains what it is, how it is made, how strong it really is, and what to know before trying it.
Key Takeaways
- THCp flower combines natural hemp flower with concentrated THCp cannabinoid through infusion or spray methods
- THCp binds to CB1 receptors up to 33 times more effectively than Delta 9 THC in early studies
- Legal THCp flower must start with hemp containing less than 0.3% Delta 9 THC by dry weight
- Potency varies by infusion method, with premium products reaching 30-40% total cannabinoid content
- Mellow Fellow's THCp flower undergoes third-party testing for cannabinoid content, heavy metals, and pesticides
What Is THCp Flower?
THCp flower refers to hemp flower that has been enhanced with tetrahydrocannabiphorol, a naturally occurring but extremely rare cannabinoid discovered in 2019 by Italian researchers.
The flower itself starts as compliant hemp - typically a high-quality strain grown for terpene profile and structure - then receives a post-harvest treatment with THCp distillate or isolate.
This process differs fundamentally from growing cannabis plants that naturally produce high THCp levels.
Natural THCp concentrations in cannabis rarely exceed 0.1% by dry weight, making extraction and infusion the only practical route to consumer-ready THCp flower products. Think of it as taking premium hemp flower and giving it a serious cannabinoid upgrade.
How THCp Flower Is Made
Most THCp flower follows a multi-step manufacturing process. Producers start with dried, cured hemp flower that passes federal compliance testing. They then apply THCp concentrate using one of two primary methods: spray application or immersion coating.
Spray methods distribute cannabinoid solution across the flower surface in thin, even layers. Immersion techniques soak the flower in cannabinoid-rich solution before a controlled drying phase.
After infusion, the flower undergoes a curing period to stabilize cannabinoid adhesion and moisture content. Premium manufacturers cure infused flower for 7-14 days in climate-controlled environments to prevent mold growth and preserve terpene integrity.
Final products then move to packaging with batch-specific lab results attached - the kind of transparency that separates legitimate products from sketchy alternatives.
THCp vs. Standard THC: Chemical Profile
THCp shares a similar molecular structure with Delta 9 THC but includes a longer alkyl side chain - seven carbon atoms compared to five. This structural difference affects how the cannabinoid interacts with the body's endocannabinoid system.
Early research from the International Journal of Molecular Science suggests THCp binds to CB1 receptors with significantly higher affinity than traditional THC, though human studies remain limited.
The longer carbon chain also influences stability and bioavailability. THCp appears more resistant to degradation under heat and light exposure than Delta 9 THC, which affects both smoking characteristics and shelf life.
Users report that THCp effects feel more intense and longer-lasting at comparable doses, though individual responses vary based on tolerance, metabolism, and consumption method. If you're coming from Delta 8 or regular THC flower, expect a noticeable step up in potency - this isn't your standard hemp flower experience.

Cannabinoid Content and Lab Verification
Quality THCp flower displays total cannabinoid content between 25% and 45% by dry weight. A typical Certificate of Analysis breaks down individual cannabinoids (THCp, CBD, CBG, trace Delta 9), terpene percentages, residual solvents, heavy metals, pesticides, and microbial contamination.
Mellow Fellow's testing protocol includes cannabinoid potency verification and full safety screening before products reach customers.
Reading a COA starts with confirming the batch number matches your product packaging. Check that THCp appears as the dominant cannabinoid and that Delta 9 THC stays below the 0.3% federal threshold.
Terpene panels show which aromatic compounds remain after processing - look for myrcene, limonene, and caryophyllene as markers of preserved flavor profile. When you buy from Mellow Fellow, you can scan the QR code on your product to pull up the exact lab results for your batch.

Legal Status and Compliance Requirements
THCp flower occupies a legal gray area shaped by the 2018 Farm Bill and evolving state regulations. Federally, hemp-derived products containing less than 0.3% Delta 9 THC remain legal under the Farm Bill's definition of industrial hemp. THCp, as a hemp-derived cannabinoid, falls within this framework when proper documentation and testing confirm compliance.
State laws vary significantly. Some states explicitly ban all THC analogs and synthetic cannabinoids, while others permit hemp-derived products without restriction. Before purchasing THCp flower, verify your state's current stance on hemp cannabinoids and check Mellow Fellow's shipping restrictions to confirm delivery eligibility.
Retailers and manufacturers face additional compliance layers. Proper licensing, batch testing, child-resistant packaging, and age verification at purchase all play into legal sales. Mellow Fellow maintains state-specific compliance through our wholesale program and updates shipping policies as regulations shift.

If you prefer loose flower for customized servings and maximum freshness, browse THCp flower jars to compare terpene profiles and potency levels. For quick sessions with no prep work, THCp infused pre-rolls offer grab-and-go convenience with consistent dosing.
How to Use THCp Flower Safely
Start with small servings - one or two inhales from a pre-roll or a pinch of loose flower - and wait 10-15 minutes to gauge effects. THCp's higher receptor affinity means standard THC doses may feel stronger.
First-time users often find that a quarter of a joint produces noticeable effects, while experienced consumers might use a full serving.
Device selection affects experience. Low-temperature vaporizers preserve terpenes and reduce harshness, with optimal temps between 350°F and 380°F.
Traditional smoking works but may degrade some cannabinoids and terpenes at combustion temperatures above 450°F. Water filtration through a bong or bubbler cools vapor and removes particulates without stripping cannabinoids.

Storage and Shelf Life
Store THCp flower in airtight containers away from direct light and heat. Glass jars with rubber seals work better than plastic bags, which allow oxygen exchange and terpene loss. Proper storage maintains potency for 6-12 months.
Refrigeration extends shelf life but requires acclimation to room temperature before use to prevent moisture condensation.
Signs of degraded flower include dry, brittle texture, faded color, and muted aroma. Cannabinoid content drops gradually over time, so older flower may require slightly larger servings to achieve the same effects as fresh product.
THCp Flower vs. Other Cannabinoid Formats
Flower offers several advantages over concentrates, edibles, and vapes.
- Inhalation delivers cannabinoids to the bloodstream within minutes, allowing users to adjust dosing in real time.
- The entourage effect from full-spectrum flower - THCp plus minor cannabinoids and terpenes - creates more complex experiences than isolate-based products.
- Compared to THCp disposable vapes, flower requires more preparation but avoids concerns about coil quality, battery life, and e-liquid additives.
- Flower also tends to cost less per mg of cannabinoid than cartridge-based products, though this varies by brand and potency level.

Terpene Profiles and Effects
Terpenes shape the character and effects of THCp flower beyond cannabinoid content alone. Myrcene-dominant strains lean sedating, with earthy, musky notes. Limonene-forward strains offer uplifting effects and citrus aroma. Caryophyllene adds spicy, peppery notes and may enhance anti-inflammatory properties.
Mellow Fellow selects base flower strains for terpene richness before THCp infusion. This approach preserves the entourage effect and delivers strain-specific characteristics alongside THCp potency. Check strain descriptions and lab results for terpene breakdowns when choosing between products.

Frequently Asked Questions
Does THCp Flower Show Up on Drug Tests?
Yes. Standard drug tests screen for THC metabolites, and THCp metabolizes into compounds similar enough to trigger positive results. Most workplace and legal drug tests cannot distinguish between Delta 9 THC, THCp, Delta-8, or other THC analogs. If you face routine testing, avoid all THC-containing products, including THCp flower.
For more details on testing timelines and detection windows, check out our article on does THCp show up in drug tests.
How Strong Is THCp Flower Compared to Regular Weed?
Potency comparisons depend on the specific products being compared. A 30% THCp flower jar may feel 2-3 times stronger per serving than a 20% Delta 9 THC cannabis flower due to THCp's higher receptor binding. However, individual tolerance, consumption method, and terpene profile all influence perceived strength. Start with smaller servings than you'd use with traditional cannabis and adjust based on response.
Our THCp potency guide breaks down exactly how strong this cannabinoid hits compared to other options.
Can You Mix THCp Flower with CBD Flower?
Yes. Many users blend THCp flower with high-CBD hemp flower to moderate effects and extend servings. A 1:3 THCp-to-CBD ratio creates milder, more balanced experiences while preserving flavor complexity. Mixing also reduces cost per session compared using pure THCp flower. CBD's calming properties can help smooth out THCp's intensity, making this a smart move for users who find THCp too strong on its own.
What's the Best Way to Try THCp Flower for the First Time?
Choose a pre-roll or small jar (3.5g) in a strain that matches your preferred time of use - indica for evening, sativa for daytime, hybrid for flexibility. Take one or two small inhales and wait 15 minutes before deciding whether to continue. Keep water nearby and have light snacks available. Avoid mixing with alcohol or other substances on your first session.
If you're feeling overwhelmed or the effects are too strong, our guide on how to sober up from weed offers practical tips to bring yourself back down.
How Long Does THCp Flower Stay Fresh?
Properly stored THCp flower maintains peak potency and flavor for 6-12 months. After that, cannabinoid degradation accelerates and terpenes begin to fade. Store your flower in airtight glass jars away from light and heat. Avoid opening the container frequently, as each exposure to air speeds up oxidation.
Is THCp Flower Natural or Synthetic?
THCp itself is a naturally occurring cannabinoid found in trace amounts in cannabis plants. However, THCp flower is technically a hemp-derived infused product. The base flower is natural hemp, and the THCp concentrate added to it comes from hemp extraction, but the infusion process is a manufacturing step. This makes it "hemp-derived" rather than fully natural in the way traditionally grown cannabis is.
Can You Travel with THCp Flower?
Travel rules vary by location and transport method. THCp flower is federally legal under the Farm Bill, but TSA guidelines and state laws create complications. Some states ban all hemp cannabinoids, and airline policies may prohibit cannabis-adjacent products regardless of legality. If you're flying, leave THCp flower at home. For road trips, check the laws in every state you'll pass through - possession can become illegal the moment you cross certain state lines.
Our shipping restrictions page lists states where we can't send THCp products, which gives you a starting point for travel planning.
