Chemical compound From Wikipedia, the free encyclopedia

1P-LSD, also known as 1-propionyl-LSD, is a psychedelic drug of the lysergamide family related to LSD. It is an ester derivative of LSD and a homologue of ALD-52 (1A-LSD). The drug originated in 2015 when it appeared as a designer drug sold online.[3] It was first synthesized as a legal LSD alternative by Lizard Labs, a Netherlands based research chemical laboratory.[4][5][6][7][8] It modifies the LSD molecule by adding a propionyl group to the nitrogen atom of LSD's indole group and is a prodrug of LSD.[9][10]

Use and effects
The dose range of 1P-LSD is 100 to 200 μg, with a typical dose estimate of 150 μg.[2] Its duration is about 8 to 12 hours for most people.[2] The subjective effects of 1P-LSD are not well-defined in the literature, although they are generally thought to be comparable to those of LSD.[11] In a 2020 study, the qualitative effects of 1P-LSD and LSD were similar when measured using visual analog scales.[1] The properties of 1P-LSD have also been assessed in other studies.[12][2]

Pharmacology
Like ALD-52 (1A-LSD), 1P-LSD is believed to act as a prodrug for LSD via hydrolysis of the propionyl group. When 1P-LSD is incubated in human serum or liver cells,[13][14] administered intravenously to rats,[15] or administered either orally or intravenously to human subjects,[1] high levels of LSD and relatively low levels of 1P-LSD are quickly detected, demonstrating that 1P-LSD is rapidly hydrolyzed into LSD in vivo following ingestion. Indeed, following intravenous administration in humans 1P-LSD is detectable in serum for no longer than 4 hours, after which it is completely converted to LSD.[1] These findings are supported by the similar duration and behavioral effects of 1P-LSD and LSD in both animal and human experiments.[13][1]

Society and culture
Legal status
As of 2015, 1P-LSD is unscheduled in the United States and Canada, but may be considered illegal if sold or used for human consumption as a structural analog of LSD under the Federal Analogue Act in the US.[13] 1P-LSD is a prohibited or controlled substance in Australia, France,[19] Finland,[20] Denmark,[21] Germany,[22] Estonia,[23] Japan,[24] Latvia,[25] Norway,[26] Romania,[27] Sweden,[28] Switzerland,[29] United Kingdom,[30] Italy,[31] Singapore,[32] the Czech Republic,[33] and Croatia.[34] 1P-LSD has been illegal in Russia since 2017 as an LSD derivative.[35]
