What is cannabis distillate?
Cannabis distillate is an extract refined toward a single cannabinoid, usually THC, until it is a clear to golden, nearly odorless oil that commonly tests at 80 to 95 percent of that cannabinoid. The refining strips out terpenes, so a distillate vape's flavor is usually added back afterward.
How it is made
Processes vary between producers, but the usual sequence has four steps.
- Extraction. A solvent such as CO2 or a hydrocarbon pulls cannabinoids and other compounds from the plant into a crude oil that still carries fats, waxes and plant matter.
- Winterization. The crude oil is dissolved in alcohol, chilled and filtered, which drops out the fats and waxes.
- Decarboxylation. Gentle heat converts acid forms such as THCA into active forms such as THC, the same change heat makes in flower.
- Distillation. Short-path or wiped-film distillation, under heat and a deep vacuum, separates compounds by their boiling points: what boils sooner, such as leftover solvent, is drawn off first, the target cannabinoid is collected as its own fraction, and heavier compounds, such as chlorophyll, stay behind.
Concentrated, not isolated
Distillate is often described as one cannabinoid with everything else stripped away, but it is not an isolate: it is concentrated toward its target cannabinoid and still carries small amounts of others. That concentration is why it tests so much higher than flower, and why a little goes a long way. Milligram-dosed formats such as edibles make it easier to start low.
The terpene trade-off
The same refining that concentrates the cannabinoid removes nearly all of the terpenes, the aroma compounds, and most minor cannabinoids, so pure distillate tastes and smells of very little. Many distillate vapes add terpenes back, either cannabis-derived ones reclaimed from the plant or botanical ones from other plants, and the label or the brand often says which (see cannabis-derived vs botanical terpenes).
Distillate or a full-spectrum extract?
Full-spectrum extracts, such as live rosin, are made to keep more of the plant's own terpenes and minor cannabinoids, and they usually test lower in THC than distillate (see live rosin vs live resin). Neither is better in general: distillate is consistent and flavor-neutral, which is why it is a common base for vapes and edibles, while a full-spectrum extract carries more of the plant's own character.
Judging a distillate
Judge one by its certificate of analysis, not its color. Check the tested potency against the label and the safety screens for contaminants such as residual solvents and pesticides. Whether its terpenes are cannabis-derived or botanical is on the label or from the brand; the certificate reports which terpenes and how much, not where they came from.
