What Is THCA and How It Can Get You High
THCA stays legal and non-psychoactive below 230°F, but becomes THC when heated. Learn the temperature rules, state laws, and contamination risks.
Written by Brandon Topp
September 19th, 2025
THCA's entire personality changes based on temperature. Keep it below 230°F, and you have a non-psychoactive, generally legal compound.
Heat it up with a lighter, vape, or even leave it on a hot dashboard, and you're holding regular THC with all the effects that come with it.
We're cutting through the confusion with a framework that makes sense.
Whether you're trying to avoid getting high, stay within the law, or understand why identical products have different legal status across state lines, everything comes down to temperature.

THCA Is What Cannabis Plants Actually Produce
THCA is tetrahydrocannabinolic acid, the natural compound that cannabis plants produce before any heating occurs.
Fresh cannabis doesn't actually contain much THC at all. The plant creates THCA, which sits there peacefully, causing no psychoactive effects.
This isn't some synthetic compound cooked up in a lab to keep cannabis products legal.
THCA is what you'd find if you picked a cannabis leaf and examined it under a microscope. The confusion comes from what happens next.
The magic number is approximately 230°F. Below this temperature, THCA remains stable and non-psychoactive.
You could eat a handful of raw cannabis leaves and feel nothing beyond maybe an upset stomach. But once you cross that temperature threshold, THCA becomes more potent, transforming into the THC everyone recognizes.
Here's how temperature affects THCA in everyday situations:
Raw consumption (70°F): Juicing, smoothies, tinctures – THCA stays intact
Vaporizing (350-400°F): Complete conversion to THC begins
Smoking (450°F+): Instant, full conversion to THC
Hot car storage (150°F+): Gradual conversion can occur over time
THCA Becomes More Potent When Heated Above 230°F
Heat above 230°F transforms THCA into Delta-9 THC through an irreversible chemical change.
Think of THCA like butter in a pan.
At room temperature, butter stays pale and mild. Apply heat, and it browns, developing completely different flavors and properties. You can't un-brown butter, and you can't turn THC back into THCA.
Is THCA the same as Delta-9? Not quite, but they're intimately related. Delta-9 THC is simply what THCA becomes after heating.
They're the same molecule separated only by heat exposure. Raw THCA has an extra carboxyl group that heat removes, fundamentally changing how the compound interacts with your body.
This explains the eternal cannabis mystery: why eating raw flower does nothing, but pot brownies send you to space.
The oven's heat during baking transforms all that THCA into THC. The same plant material yields an entirely different outcome, based solely on temperature.
Why THCA Products Exist in a Legal Gray Area
Dispensaries sell THCA because the 2018 Farm Bill only restricts Delta-9 THC content, creating an opportunity for high-THCA hemp that becomes psychoactive when heated.
The law restricts Delta-9 THC content to 0.3% or less, but doesn't mention THCA. Technically, a hemp flower containing 20% THCA and 0.2% Delta-9 THC passes federal requirements.
Why are dispensaries selling THCA? Because current federal testing measures THC content before heating.
That high-THCA flower tests as legal hemp right up until someone lights it. Then it becomes identical to marijuana, producing the same effects.
All of Mood’s flower is THCa and Farm Bill compliant.
Your State Might Test Hemp After Heating
THCA is federally legal when derived from hemp containing less than 0.3% Delta-9 THC, though states test and enforce differently.
However, federal legality means little when your state tests differently or your local prosecutor decides to make an example. The technical federal legality offers cold comfort during an arrest.
Mood.com makes it easy to find THCa flower and other hemp-derived products available in your state.
Simply navigate to the top right corner of any Mood page, choose the state you’d like the product delivered to, and shop on.
Raw THCA Offers Different Experiences Without Impairment
Unlike THC, raw THCA doesn't bind strongly to CB1 receptors in the brain, meaning no psychoactive effects.
Research suggests THCA may provide certain effects that some users find beneficial.
Unlike THC, raw THCA doesn't bind strongly to CB1 receptors in the brain, meaning no psychoactive effects while potentially offering other experiences that users report as positive.
Some choose THCA over CBD because it works through different mechanisms in the body.
While CBD indirectly influences the endocannabinoid system, THCA appears to interact with other pathways, potentially offering distinct experiences.
Raw cannabis juicing has gained popularity among enthusiasts who want these potential experiences without any impairment.
Common raw consumption methods include blending fresh leaves into smoothies, using THCA tinctures that haven't been heated, or taking crystalline THCA isolate.
The key is to keep everything below the crucial 230°F threshold. Mood does not recommend the consumption of raw cannabis flower.
THCA vs CBD vs Delta-8: Understanding Your Cannabinoid Options
Understanding how THCA compares to other cannabinoids helps you choose the right product for your needs.
THCA vs CBD: These are fundamentally different compounds. CBD remains non-psychoactive regardless of temperature and interacts with the endocannabinoid system through indirect pathways. THCA also stays non-psychoactive when raw, but transforms into psychoactive THC when heated. They're not substitutes – they're different tools with different properties.
THCA vs Delta-8 THC: Delta-8 is already psychoactive and typically synthesized from CBD through chemical processes. THCA is naturally occurring in cannabis plants and only becomes psychoactive through heat. Delta-8 produces milder effects than Delta-9 THC, while heated THCA becomes Delta-9 THC at full strength.
THCA vs Delta-9 THC: THCA is the precursor – the raw, non-psychoactive form. Delta-9 THC is the end result after heat application. You can't have Delta-9 from cannabis without first having THCA.
Legal status comparison: CBD is legal in all 50 states under the Farm Bill. Delta-8 exists in a gray area, with several states banning it explicitly. THCA's legality depends on whether your state tests before or after heating, and whether they include it in total THC calculations. Delta-9 THC remains federally illegal outside the 0.3% hemp threshold.
When choosing between these cannabinoids, consider: Do you want psychoactive effects? If yes, you'll need Delta-8, Delta-9, or heated THCA. If not, both raw THCA and CBD remain non-psychoactive. Temperature control is everything with THCA. It's the only cannabinoid that transforms based on how you use it.
How You Consume THCA Determines What Happens
Your consumption method is everything when it comes to THCA. Raw methods preserve the compound's non-psychoactive nature. Juice it, blend it, or take it in capsules. As long as you avoid heat, you avoid the high.
But here's where people get confused: THCA gummies won't get you high because they're made without heating.
THCA flower, however, becomes fully psychoactive the moment you spark it. The same compound yields completely different outcomes based on temperature exposure.
Watch: How To Use Cannabis Flower
Temperature-controlled devices allow you to tailor your experience precisely.
Vapes with exact temperature settings allow you to stay below the conversion threshold for flavor without effects, or dial it up for full activation. You control the outcome by controlling the heat.
Dabbing THCA "diamonds" at high temperatures guarantees complete conversion to THC. Meanwhile, adding those same diamonds to a room-temperature smoothie maintains their THCA form.
The product doesn't determine the effect. Your preparation method does.
THCA Side Effects Change Completely With Heat
Raw THCA consumption might cause mild digestive issues like nausea or upset stomach in some people.
These effects typically stay minor since THCA doesn't strongly activate cannabinoid receptors without heat.
Apply heat, though, and you're dealing with regular THC side effects: euphoria, altered perception, dry mouth, and fun.
The compound that caused zero psychoactive effects at breakfast could leave you couch-locked by dinner if you heated it.
Will THCA get you stoned? Only if you heat it above 230°F. But accidental heating happens more than people realize.
Leaving THCA products in a hot car, cooking with them, or even holding a lighter too close to THCA crystalline can trigger conversion.

Why Drug Tests Detect THCA Regardless of Temperature
Drug tests don't care whether you consumed THCA or THC. Your body produces similar metabolites from both, and these metabolites trigger positive results.
Even if you only consumed raw THCA, never heating it, traces may show up on a drug test.
The detection window varies by consumption method and frequency, but regular THCA users should assume they'll test positive for weeks after stopping.
Employers typically use tests that look for THC metabolites without distinguishing the source.
Explaining that you only used "legal THCA" rarely changes the outcome. If your job depends on clean drug tests, THCA products pose the same risks as traditional cannabis.
The Hidden Contamination Risk in Unregulated THCA
The hemp-derived THCA market operates with minimal oversight. Unlike dispensary products that undergo mandatory testing, many THCA products sold online or in smoke shops never see a laboratory.
Unregulated products may contain pesticides, heavy metals, or molds that pose serious health risks.
We've seen reports of THCA flower testing positive for banned pesticides at levels that would fail any state's dispensary standards.
This is why we invest in comprehensive third-party testing for our entire product line.
Every batch gets analyzed for potency, pesticides, heavy metals, and microbials. You deserve to know exactly what you're consuming, especially in a market where many vendors cut corners to compete on price.
Making Smart THCA Decisions Starts With Temperature
Everything we've covered boils down to one principle: temperature determines outcome.
Below 230°F, THCA remains non-psychoactive and generally legal. Above that threshold, you're dealing with THC in every practical sense.
Your goals determine your approach. Want potential wellness benefits without impairment? Keep THCA raw through juicing, tinctures, or capsules.
Looking for recreational effects? Any heating method will activate the compound fully.
Concerned about legal issues? Know your state's testing methods and enforcement patterns.
The temperature principle explains every confusing aspect of THCA, like:
Why identical products have different effects
Why state laws vary so dramatically
Why that "legal" purchase might still cause problems
Once you understand that THCA and THC are separated only by heat, everything else falls into place.
We're here to provide tested and labeled products that enable you to make informed choices.
Whether you're exploring THCA for the first time or looking for consistent, contamination-free options, understanding the temperature relationship empowers you to control your experience.
