Cannabis distillate is made by pulling cannabinoids out of plant material with a solvent or heat, cleaning up the crude extract, then separating cannabinoids from waxes, fats and pigments inside a vacuum distillation rig. The result is a near-pure THC or CBD oil that often tests between 80 and 95 percent total cannabinoids. If you are shopping rather than processing, the pick that fits most buyers is a lab-tested distillate vape cartridge with a stated cannabinoid percentage and a clear terpene source. Judge any distillate product on three criteria: the cannabinoid number on the label, the batch test results behind it, and how the terpenes were handled. The sections below walk through how the oil in that cartridge gets made.

The Short Answer
Distillate is a refined concentrate, not a whole-plant extract. Producers make it in five stages: extraction, winterization, decarboxylation, distillation, and formulation. Each stage removes something, first plant material, then waxes and lipids, then acid groups, then everything that is not a cannabinoid. What is left is a thick amber or clear oil that carries little smell and almost no plant flavor on its own.
Cannabis Distillate Cart Not Hitting: What to Expect When You Visit a Cannabis Store
Step 1: Extraction
The starting point is dried cannabis flower or trim. A licensed producer runs it through one of several extraction methods:
- Hydrocarbon extraction with butane or propane in a closed-loop system
- Ethanol extraction, common at large scale because it is fast and cheap
- Supercritical CO2 extraction, which allows fine tuning of pressure and temperature
The output at this stage is called crude oil. It contains cannabinoids, terpenes, waxes, chlorophyll and other plant compounds, so it is usable but not clean enough for distillation.
Step 2: Winterization and Filtration
Crude oil is dissolved in ethanol, chilled well below freezing, and left to sit. Cold temperatures make fats, waxes and lipids drop out of solution so they can be caught in a filter. Skipping this step causes scorching and clogged glassware during distillation. After filtration the ethanol is recovered, leaving a thinner, cleaner oil.
Step 3: Decarboxylation
Raw cannabis holds THC and CBD in their acid forms, THCA and CBDA. Heat converts those acids into the active neutral forms and releases carbon dioxide as a byproduct. Decarboxylation matters for distillate because THCA does not vaporize at the temperatures a vape or dab rig reaches, and because the acid forms have higher boiling points that would interfere with the distillation run.
Step 4: Distillation
Distillation separates compounds by boiling point. Because cannabinoids would degrade at atmospheric boiling temperatures, producers pull a vacuum that lowers the boiling point enough to vaporize cannabinoids without burning them. Two setups dominate:
- Short path distillation: material travels a short distance under vacuum to a condensing surface. Common for small and mid-size batches.
- Wiped film (rolled film) distillation: oil spreads into a thin layer on a heated cylinder, which increases surface area and allows continuous flow. Common at commercial scale.
Each run is collected in fractions. The first fraction, called heads, holds volatile compounds and some terpenes. The middle fraction, called the main body, is the cannabinoid cut. The final fraction, called tails, holds heavier compounds and darker material. Skilled operators repeat the run to raise purity, and testing confirms the cannabinoid profile of each lot.
Step 5: Formulation and Filling
Purified distillate is thick and nearly flavorless. Producers thin it for cartridges and add terpenes back for flavor. Terpenes may come from cannabis (cannabis-derived), from other plants (botanical), or from a blend. Some distillate is left unflavored for edibles and topical manufacturing, where a neutral base is an advantage. The finished oil is then filled into carts, jars or syringes and sent for potency and contaminant testing.
Distillate Compared With Full-Spectrum Extract
Pros of distillate
- High and consistent cannabinoid content, which makes dosing predictable
- Neutral taste and low odor, useful for edibles and for buyers who dislike skunk flavor
- Long shelf life because reactive plant compounds have been removed
- Versatile: works in vapes, dabs, edibles, tinctures and topicals
Cons of distillate
- Lost minor cannabinoids such as CBG, CBN and CBC that appear in whole extracts
- Lost native terpenes, so flavor depends on what gets added later
- Added terpenes vary in quality and can taste sharp or harsh at high levels
- Effects can feel narrow compared with a full-spectrum product
Pros of full-spectrum extracts
- Keeps a wider cannabinoid and terpene range found in the original plant
- Flavor and aroma tie back to the strain
Cons of full-spectrum extracts
- Lower cannabinoid percentages, harder to dose by number alone
- Stronger odor and flavor, which some buyers avoid in public settings
- More batch variability from lot to lot
Which One to Buy
Choose distillate if you want a precise, repeatable dose, if you plan to cook, or if you want a cartridge that does not announce itself. Choose full-spectrum or live resin if flavor and a broader range of plant compounds matter more than peak percentage. For a first cartridge, a 1 gram distillate cart with a published test panel and cannabis-derived terpenes is the lower-risk purchase, since potency and consistency are simpler to verify than flavor.
What to Check on the Label Before You Pay
- Total THC and total CBD percentages, not just the single highest number
- A batch or lot number you can match to a test result
- Terpene source, listed as cannabis-derived, botanical, or not specified
- Contaminant screening for pesticides, heavy metals, residual solvents and microbials
- Cart hardware and coil type, since distillate is thick and some coils handle it better than others
Ask the person behind the counter for the test panel if it is not printed on the package. A shop that keeps panels on hand is easier to buy from with confidence than one that quotes a number with nothing behind it.
