1P-LSD

Safety profile
Category: Psychedelic
Main effects: Open and closed eye visuals, euphoria, change in perception of time. Anecdotal report of being indistinguishable from LSD.
Side effects: Nausea, vasoconstriction (mostly when combined with other vasoconstricting substances like LSD), unusual body sensations (facial flushing, chills, goosebumps, body energy), slight increase in heart rate, difficulty focusing
Health risks: Mental: paranoia, fear, and panic. Hallucinogen persisting perception disorder. No other known specific physical risks at this time (but likely similar to LSD).
Important safety remarks: 1P-LSD is a substance not mentioned in academic literature, with little known about its pharmacological or behavioral risks. The LD50 (median lethal dose) is not known. No studies on this substance have been performed, so long term effects and potential risks are UNKNOWN!

1P-LSD

Brief overview - What is 1P-LSD?

• Systematic (IUPAC) name: (6aR,9R)-4-propionyl-N,N-diethyl-7-methyl-4,6,6a,7,8,9-hexahydroindolo[4,3-fg]quinoline-9-carboxamide]

Chemical and physical properties

From an old Wikipedia draft:
Sharing a strong structural similarity with ALD-52, the chemical purportedly used in the 1960's Orange Sunshine 1P-LSD follows the less common path of modifying the 1- position on the LSD molecule which in the past has been avoided due to unpredictable results or lack of activity. Lots of debate is surrounding the action of 1P-LSD and is unclear exactly how the chemical is functional with an unconfirmed quote from David E. Nichols believing the chemical should be inactive while most other speculation believing it would simply follow the same metabolic path as ALD-52 and undergo conversion in vivo to LSD.

"I am sure that the 1-propionyl would also hydrolyze off of an indole, but I don't know whether in vivo conditions would work. In a chemistry lab, you can get off an N-benzoyl, so an N-propionyl will probably come off too. But in the body? I don't know the answer to that. The compound would not be active as the N-propionyl however. Way that LSD docks into the 5-HT2A receptor, the indole NH hydrogen bonds to serine 5.46. With the propionyl, it won't fit into the receptor."
