Leafly's cannabis glossary credits both terms to Dr. Daniel Hayden of Extractioneering, an Oregon company. It defines HCFSE as a full-spectrum concentrate with high levels of major and minor cannabinoids, with a gritty, granular look that comes from its high THCA content.
HTFSE is the terpene side. Leafly puts its terpene content at 13 to 40%, notes that it often carries plenty of THCA as well, and describes it as resembling an oil, sauce or resin, which is why it also goes by terp sauce. Our terpene guide covers the aroma compounds themselves.
How does one extract become two?
Weedmaps describes the split: when a full-spectrum extract made from cannabis flowers is left to separate under the right conditions, it forms a gritty, saucelike HTFSE and an HCFSE that tends to come out as sugar or diamonds. Our THCA diamonds guide explains how those are made.
Leafly counts sauces and live resin among the popular HTFSE products.
How are HTFSE and HCFSE used?
Both are dabbed. Health Canada describes dabbing as inhaling an aerosol made by vaporizing a solid or semi-solid extract at high temperature, using a nail heated by a torch or an electric element. The heat matters: the THCA in both fractions turns into active THC when heated, Weedmaps explains. Our dabbing guide walks through the equipment.
In a 2017 study in ACS Omega, Portland State University chemists heated common cannabis terpenes on a dab nail: the irritant methacrolein appeared from about 403 °C up, the carcinogen benzene only in the hottest range near 526 °C, and neither was detected around 322 °C. The authors note that most dabbers run hot to avoid wasting material and that torch-heated nails are hard to control. Health Canada's lower-risk guidelines add: avoid deep inhalation and breath-holding.
How strong are they?
Very. Health Canada's lower-risk guidelines say concentrates contain extremely high THC, and its lower-your-risks advice is for new or occasional users to avoid extracts, since higher amounts of THC mean more impairment and a greater risk of serious adverse effects. The lower-risk guidelines also steer people toward lower-THC products.
How should you store sauce and crystals?
Health Canada's labelling rules name temperature, light and humidity as the storage conditions that protect a cannabis product's quality, so follow any directions on the jar and keep it sealed somewhere cool, dark and dry. As with all cannabis, Health Canada advises locking it up where children and pets can neither see nor reach it.
Why this category is sometimes empty
Stock in this category rotates, so the grid here can sit empty between batches. To see what the menu carries today, browse concentrates, resin and shatter. GTA and Toronto addresses get same-day delivery, usually within 1 to 2 hours, while the rest of Canada is served by tracked mail.

HTFSE / HCFSE, frequently asked questions
Q.Is HTFSE the same as terp sauce?
Often, not always: Weedmaps notes that a sauce only qualifies if its extraction separated the terpene-rich fraction from the cannabinoid-rich one.
Q.Which is stronger, HTFSE or HCFSE?
HCFSE, by THCA content: Weedmaps puts it near 90% THCA against roughly 50% for HTFSE. Both sit in the extremely high THC range Health Canada warns about.
Q.Can you put HTFSE in a vape pen?
Use a dab pen: Health Canada explains that dab pens melt solid and semi-solid extracts, while regular vaping devices are built for liquids and oil.
Q.Can you eat HCFSE?
Not as it comes. THCA needs heat to become THC, so these extracts are vaporized rather than swallowed raw.
