Replaced reference for the 500 mcg experience report of Hofmann's with the source (i.e. I replaced Shugin's summary with Hofmannn's publication) and removed the quotes around summary, since it's not a quote, and added a detail.

“D-lysergic acid amide (designation of compound undergoing tests: LA 111) was tested pharmacologically and clinically during the course of investigations on d-lysergic acid diethylamide (LSD 25) and related compounds long before it was known to be a component of ololiuhqui. Already at that stage we had, in experiments on ourselves, ascertained a psychotomimetic activity with a marked narcotic component with dosages of 0.5 to 1 mg. The following paragraph is taken from a hitherto unpublished record of the first experiment which the writer performed upon himself with LA 111 on 30.10.1947.”
 
10.00 h: Intramuscular injection of 0.5 ml of 1 per mille solution of LA 111 ( = 0.5 mg d-lysergic acid amide).
 
11.00 h: Tiredness in the neck, slight nausea.
 
11.05 h: Tired, dreamy, incapable of clear thoughts. Very sensitive to noises which give an unpleasant sensation.
 
11.10 h: Desire to lie down and sleep. Genuine physical and mental tiredness, which is not experienced as an unpleasant sensation. Slept for 3 hours.
 
15.00 h: Return of normal condition with full capacity for performing work.
 
“This action of d-lysergic acid amide was later confirmed by the comparative systematic investigation of H. Solms.<sup>26 27</sup> He describes the action as follows: LA 111 induces indifference, a decrease in psychomotor activity, the feeling of sinking into nothingness and a desire to sleep . . . until finally an increased clouding of consciousness does produce sleep.”
 
This plant is now considered to be ''Ipomoea tricolor''.
 
“Such a confusing example resulting in numerous false repetitions in studies of other authors has happened already in the first ergoline paper on ''Ipomoea tricolor'' Cav. whose seeds are known as “badoh negro”: Together with this correct synonym the species was incorrectly called ''I. violacea'' L. (Hofmann 1964) instead of ''I. violacea'' '''auct., non L.''' This is of importance since ''I. violacea'' L. is the currently accepted name of a different ''Ipomoea'' species, ''I. tuba'' (Schlecht.) G.Don (Austin and Huáman 1996).”

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. Many users report serious [[nausea]] and bodily discomfort ("body load") when taking LSA-containing seeds.
