User reports describe the effects of LSA as primarily sedating and dream-like, with a mild to moderate psychedelic component. The psychedelic effects of LSA occur inconsistently and are not directly comparable to the effects of classical psychedelics like [[LSD]], [[psilocybin mushrooms]], or [[mescaline]]. LSA is described as primarily bodily and cognitive with little visual effects.

LSA, or d-lysergic acid amide, is an organic alkaloid belonging to the [[lysergamide]] class. The chemical structure of LSA contains a core structure of lysergic acid with an amine functional group bound to R<sub>N</sub>. The structure of lysergic acid is composed of a bicyclic hexahydroindole fused to a bicyclic quinoline group (lysergic acid). At carbon 8 of the quinoline, an acetamide group is bound. LSA is additionally substituted at carbon 6 with a methyl group. | LSA, or d-lysergic acid amide, is an organic [[alkaloid]] belonging to the [[lysergamide]] class.

LSA is a chiral compound with two stereocenters at R<sub>5</sub> and R<sub>8</sub>. LSA, also called (+)-D-LSA, has an absolute configuration of (5''R'', 8''R''). The three other stereoisomers of LSA do not have psychoactive properties. LSA is structurally analogous to LSD, with the exception being that LSA lacks the diethyl substitution of LSD at R<sub>N</sub> of its carboxamide group. It can be used as a precursor to LSD. | LSA is a chiral compound with two stereocenters at R<sub>5</sub> and R<sub>8</sub>.

However, the seeds from commercial sources are often coated in some form of seed treatment or fungicide which can result in extreme nausea, bodily discomfort, or (in the case of organomercury compounds) long-term neurological damage and cognitive impairment if ingested. Methods for cleaning or de-coating the seeds are available, but are typically ineffective (organomercury compounds penetrate the entire seed). Therefore it is important to only purchase untreated seeds from reliable, trusted vendors. Heavy metal testing kits can be purchased online to test seed extracts for mercury content prior to ingestion. | ||
