Salvia divinorum 40X extract
The 40X designation indicates the concentration ratio relative to untreated dried leaves. The extract contains 144 mg of salvinorin A per gram and is produced by impregnating dried Salvia divinorum leaves with a concentrated salvinorin A solution. After drying, this yields a homogeneous product with a consistent active ingredient content. The package contains 0.5 grams, which allows for a large number of sessions at the recommended starting dose.
The 40X is among the higher concentrations in the Salvia divinorum range at Dutch-Smart. Users with no experience with salvia extracts above 20X are strongly advised to take intermediate steps via the 30X variant before using the 40X.
Active ingredient and effects
The psychoactive effect of Salvia divinorum is entirely due to salvinorin A, a terpenoid compound that is unique among psychoactive plant substances. It is the only known potent non-alkaloid psychedelic and acts as a selective kappa-opioid receptor agonist, with no affinity for the serotonin 5-HT2A receptor targeted by classic psychedelics such as psilocybin and LSD.
Users report that the effects are characterized by a profound shift in perception, during which the boundaries between the self and the environment may blur. The sense of time can become severely distorted, and the perception of space often changes fundamentally. The total duration of the peak phase is short, typically two to five minutes when smoked, which distinguishes the experience from most other psychedelics.
With 144 mg of salvinorin A per gram, the 40X is the strongest extract, with the active dose measured in hundredths of a gram. The physiological breakdown rate of salvinorin A is high, which explains the short but intense duration of action.
Origin and Cultural Context
Salvia divinorum originates from the Oaxaca mountains in southern Mexico, where the plant was cultivated for centuries in small, isolated communities by the Mazatec people. In shamanic rituals, the leaves were traditionally chewed or taken as an infusion to induce prolonged, introspective experiences. The active ingredient when taken orally is the same as when smoked, but the pharmacokinetics differ significantly: oral administration results in a slower onset and a duration of one to two hours rather than minutes.
The 40X extract no longer has a direct relationship with the traditional method of use. The high concentration and the inhalation method produce effects that are quantitatively and qualitatively different from the ritual context of origin.
Use and Dosage
Salvia extract is smoked using a pipe or bong. A starting dose for the 40X is 0.01 to 0.02 grams per session. The amount is completely burned in a single long inhalation and held in the lungs for as long as possible, typically 20 to 30 seconds, for maximum absorption through the lung tissue. The onset occurs within 5 to 30 seconds after exhaling.
Always weigh accurately using a precision scale that measures hundredths of a gram. With the 40X, 0.01 grams is the practical minimum that can be accurately weighed; never estimate by eye. Start with the lowest possible amount and wait at least one day before considering a follow-up dose.
A hookah or bong cools the smoke and makes it easier to inhale the entire amount in a single puff. Vaporizing requires a temperature of approximately 240 °C; check out our selection of portable vaporizers.
Storage
Store the extract in a dry, cool place away from direct sunlight. Salvinorin A is sensitive to light degradation and oxidation; store it in the original, sealed packaging. When stored correctly, the potency remains stable for a long time.
Harm reduction
Salvia divinorum is one of the most potent known psychoactive plants. At the 40X concentration, the effects are almost always completely disorienting, and the ability to exercise self-control may be completely lost. Use only in a safe, familiar environment.
Never use alone. Always ensure a sober companion remains present for the entire duration of the effects and can physically intervene if necessary. Choose a safe sitting position on the floor or in a low chair; never stand or be near water, fire, or stairs. Remove all dangerous objects from the immediate vicinity before beginning.
Do not combine salvia with alcohol, cannabis, benzodiazepines, or other psychoactive substances. Driving and operating machinery are strictly discouraged during and for at least several hours after use. Do not use if you have a history of psychiatric conditions, particularly a predisposition to psychosis or dissociative disorders, and do not use during pregnancy or while breastfeeding.
Salvia divinorum is not listed under the Opium Act in the Netherlands and is legally available to individuals 18 years of age and older. Check the laws in your own country before purchasing or importing.

Frequently Asked Questions
What makes the 40X different from the 30X?
The 40X contains 144 mg of salvinorin A per gram, compared to approximately 108 mg in the 30X. Even less material is needed per session, and the intensity is correspondingly higher. Users who are not yet familiar with the 30X are strongly advised to explore it thoroughly first before moving on to the 40X.
How many grams should I use per session with the 40X?
The starting dose is 0.01 grams. This is also the minimum amount that can be accurately weighed using a precision scale. Never estimate by eye with this extract. Never take a second dose while the first is still active.
Why are the effects so short but so intense?
Salvinorin A is rapidly metabolized by the body, which explains the duration of five to fifteen minutes when smoked. The intensity is independent of the duration: kappa-opioid receptor activation produces a dissociative experience profile that differs qualitatively from serotonergic psychedelics. The combination of high concentration and rapid onset results in an abrupt, overwhelming experience without the gradual build-up that occurs with many other substances.
Is this extract legal in the Netherlands?
Yes. Salvia divinorum and its extracts are not covered by the Opium Act and are legally available for purchase in the Netherlands by individuals 18 years of age and older. In a number of other European countries, the plant is prohibited; check local regulations before purchasing or importing.
