Toxicology – Salvia (Salvia divinorum)
Source
Salvia divinorum is a plant from the mint family native to Oaxaca, Mexico. Its leaves or concentrated extracts are commonly sold online or in specialty shops and are typically smoked to produce psychoactive effects.
Typical Presentation
Users often experience a rapid onset of intense but short-lived hallucinations after smoking. During intoxication, individuals may appear disconnected from reality, mumbling, or reacting to internal stimuli. Upon recovery, they may describe vivid, unusual experiences or feelings of entering alternate realities.
Clinical Features
Effects are brief, usually lasting only a few minutes. Common features include visual and tactile hallucinations, dissociation, inappropriate laughter, altered perception of reality, and unusual sensations such as merging with objects or changes in body form. Some individuals experience distress or fear during recovery, similar to an emergence reaction seen with dissociative anesthetics.
Mechanism of Action
The active compound, salvinorin A, is a potent and selective kappa-opioid receptor agonist. Unlike traditional opioids, it does not significantly depress respiration.
Management
Treatment is supportive. Because symptoms are short-lived, most cases resolve without medical intervention. Reassurance is usually sufficient for individuals experiencing anxiety or a “bad trip.”

Key Points
- Effects are rapid in onset and short in duration compared to many other hallucinogens.
- The substance is often smoked using specialized equipment due to its high vaporization temperature.
- Oral ingestion is generally ineffective because the active compound is inactivated in the gastrointestinal tract.
- Many users report the experience as unpleasant and do not continue use.
