Identity note

Wild lettuce is included because it appears frequently in contemporary smoking-herb lists. Historical names and anecdotes are not evidence of a safe or effective preparation.

Evidence status

What the record supports

TraditionalPreclinicalNo established dose

Claim-level citations will be published only after source review. Extract studies and preparation-specific findings will not be converted automatically into loose-herb dosing.

Cautions

Read before use

Published case reports describe serious toxicity after ingestion, including agitation, urinary retention, cardiovascular effects, and intensive-care monitoring. No safe inhaled dose is established. Lot & Leaf does not recommend using wild lettuce, combining it with sedatives or alcohol, or using it during pregnancy or nursing.

This educational record is not a diagnosis, treatment recommendation, or substitute for individualized medical advice.

Inhalation context

Tradition is not a safety test

Online sources describe wild lettuce as sedating or psychoactive; those claims should not be read as a safety endorsement. It remains reference-only while toxicology, legality, and product suitability are reviewed.
