What Is a Mushroom Vape Pen?
A mushroom vape pen, commonly called a shroom pen or shroom vape, is a disposable vaporizer containing an extract derived from Amanita muscaria rather than from psilocybin mushrooms. The active compound is usually muscimol, sometimes alongside ibotenic acid, dissolved in a carrier and delivered by inhalation.
That distinction is the most important thing on this page, so it gets its own section immediately below.
These are not psilocybin products
Psilocybin is a Schedule I controlled substance under federal law, and so are the mushrooms that contain it. Amanita muscaria contains no psilocybin. It contains muscimol and ibotenic acid, which are unrelated compounds and are not federally scheduled.
Products in this category are made from amanita. They are legally distinct from psilocybin products, and any product marketed to you as delivering a psilocybin experience is either mislabeled or illegal. If a listing is ambiguous about which mushroom it derives from, treat that ambiguity as the answer.
How a mushroom vape works
Mechanically it is a standard disposable vaporizer. A battery heats a coil, the coil heats a liquid held in a reservoir, and the resulting aerosol is inhaled. The hardware is generally identical to hemp cannabinoid disposables.
What differs is the fill. An amanita extract has to be made soluble in a carrier such as propylene glycol or vegetable glycerin to be vaporized at all, which requires processing that varies substantially between manufacturers. Muscimol and ibotenic acid have different thermal stability from cannabinoids, and there is no established consensus on what temperature range preserves the compound versus degrades it.
What is actually known about inhaling muscimol
Very little, and the page would be doing you a disservice to pretend otherwise.
Amanita muscaria has a long history of traditional oral use, and there is a body of literature on oral muscimol. Inhalation is a different route of administration with a different absorption profile, and it is essentially unstudied. There are no published pharmacokinetic studies on inhaled muscimol, no established dose-response data, and no safety literature on chronic inhalation of muscimol-containing aerosols.
Separately, the ibotenic acid question applies here as it does to edibles. Proper processing decarboxylates ibotenic acid into muscimol. Incomplete processing leaves ibotenic acid present in higher quantities, and it is the compound associated with the less pleasant end of the amanita profile. Whether a given extract was properly converted is not visible from the packaging.
This is not a claim that these products are dangerous. It is a statement that the evidence base a consumer would want does not exist yet, and that anyone presenting confident safety information about inhaled muscimol is going beyond what is known.
Where the law stands
Amanita muscaria is not federally controlled. Louisiana restricts it when intended for human consumption under Act No. 159. No other state has a specific statute controlling it as of September 2026.
In December 2024 the FDA determined that Amanita muscaria and its constituents are not Generally Recognized as Safe for use in food, making amanita-containing food adulterated under the Federal Food, Drug, and Cosmetic Act. That determination addresses food. Its application to an inhaled product is less clearly defined, which is a gap rather than a permission.
Brands you will encounter
Psyched, Flux, Mushiez and Shroom Puff all appear in search as named products in this category. They are listed here because people encounter them and want to know what they are. This is not a ranking and nothing here should be read as a recommendation.
Across all of them the same verification problem applies, and it is more acute than in the edible category because the inhalation route adds hardware quality to the list of unknowns.
What to check before buying
- Confirm the product states Amanita muscaria explicitly. Vague “mushroom extract” labeling tells you nothing.
- Look for a batch-matched certificate of analysis from an ISO 17025 accredited lab, showing muscimol and ibotenic acid content separately.
- Check for contaminant screening, including heavy metals, which matters more for inhaled products because of the hardware.
- Confirm the carrier is disclosed. If the listing does not say what the extract is dissolved in, that is a meaningful omission.
- Check your state position, and note that regulation in adjacent categories has moved quickly.
Frequently asked questions
Are mushroom vapes legal?
Amanita muscaria is not federally scheduled and only Louisiana restricts it. The FDA has determined amanita is not GRAS for food use, which is a separate regime from controlled substance law.
Do mushroom vapes contain psilocybin?
No. Legal products in this category are made from Amanita muscaria and contain muscimol, not psilocybin. Psilocybin is Schedule I.
Is inhaling muscimol safe?
There is no published safety literature on inhaled muscimol. The honest answer is that it has not been studied, which is different from it having been shown to be safe.
How is a mushroom vape different from a THC vape?
The hardware is generally the same. The fill is an amanita-derived extract rather than a cannabinoid, and the two are regulated under entirely separate frameworks.
What is the difference between muscimol and ibotenic acid?
Ibotenic acid is the precursor compound; proper processing converts it to muscimol through decarboxylation. Incomplete conversion leaves more ibotenic acid in the finished product.
General information only. Not medical advice and not a recommendation to use any product. Amanita muscaria products are not approved by the FDA for food use or for any therapeutic purpose, and inhaled muscimol has not been studied for safety. Last reviewed September 2026.
