1P-LSD (1-propanoyl-lysergic acid diethylamide) is a psychedelic drug of the lysergamide class that is a derivative and functional analogue of LSD and a homologue of ALD-52. It originated in 2015 when it appeared a designer drug sold online. [1] It was first synthesized as a legal-LSD alternative by Lizard Labs, a Netherlands based research chemical laboratory. [2] [3] [4] [5] [6] [7] It modifies the LSD molecule by adding a propionyl group to the nitrogen atom of LSD's indole group. [8] [9]

Pharmacology

Like ALD-52, 1P-LSD is believed to act as prodrug for LSD via hydrolysis of the propionyl group. When 1P-LSD is incubated in human serum, [10] administered intravenously to rats, [11] or administered either orally or intravenously to human subjects, [12] 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. [12] These findings are supported by the similar duration and behavioral effects of 1P-LSD and LSD in both animal and human experiments. [10] [12]

Effects

The subjective effects of 1P-LSD are not well defined in the scientific literature, although they are generally thought to be comparable to that of LSD. [13] In a 2020 study, the qualitative effects of 1P-LSD and LSD were similar when measured using visual analog scales.

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. [10] 1P-LSD is a prohibited or controlled substance in Australia, France, [14] Finland, [15] Denmark, [16] Germany, [17] Estonia, [18] Japan, [19] Latvia, [20] Norway, [21] Romania, [22] Sweden, [23] Switzerland, [24] United Kingdom, [25] Italy, [26] Singapore, [27] the Czech Republic, [28] and Croatia. [29] 1P-LSD has been illegal in Russia since 2017 as an LSD derivative. [30]

<span class="mw-page-title-main">LSD</span> Hallucinogenic drug

Lysergic acid diethylamide, commonly known as LSD, is a potent psychedelic drug that intensifies thoughts, emotions, and sensory perception. Often referred to as acid or lucy, LSD can cause mystical, spiritual, or religious experiences. At higher doses, it primarily induces visual and auditory hallucinations. While LSD does not cause physical addiction, it can lead to adverse psychological reactions, such as anxiety, paranoia, and delusions. Additionally, it may trigger "flashbacks," also known as hallucinogen persisting perception disorder, where individuals experience persistent visual distortions after use.

<span class="mw-page-title-main">Lysergic acid</span> Precursor for a range of ergoline alkaloids produced by the ergot fungus

Lysergic acid, also known as D-lysergic acid and (+)-lysergic acid, is a precursor for a wide range of ergoline alkaloids that are produced by the ergot fungus and found in the seeds of Turbina corymbosa (ololiuhqui), Argyreia nervosa, and Ipomoea tricolor.

<span class="mw-page-title-main">Lysergamides</span> Class of chemical compounds

Amides of lysergic acid are collectively known as lysergamides, and include a number of compounds with potent agonist and/or antagonist activity at various serotonin and dopamine receptors. Lysergamides contain an embedded tryptamine structure, and as a result can produce similar, often psychedelic, effects to those of the true tryptamines.

<span class="mw-page-title-main">ALD-52</span> Chemical compound

ALD-52, also known as 1-acetyl-LSD, has chemical structural features similar to lysergic acid diethylamide (LSD), a known psychedelic drug. Similarly, ALD-52 has been reported to produce psychoactive effects, but its pharmacological effects on humans are poorly understood. Given its psychoactive properties, it has been reported to be consumed as a recreational drug, and the purported first confirmed detection of the substance on the illicit market occurred in April 2016.

<span class="mw-page-title-main">Lysergic acid hydroxyethylamide</span> Chemical compound

D-Lysergic acid α-hydroxyethylamide, also known as D-lysergic acid methyl carbinolamide, is a Lysergamide and alkaloid of the Ergoline family, it is present in higher concentrations in the parasitic fungi species "Claviceps", mainly the Claviceps paspali, also in Claviceps Purpurea. This fungi grows in various species in the Convolvulaceae family like the Ipomoea violacea, the Rivea corymbosa (Ololiuhqui), and the Argyreia nervosa. Heavenly Blue Morning Glory and Hawaiian Baby Woodrose especially contain high amounts of LSH, with content varying between species and by how fresh the seeds are. LSH is a psychoactive Ergoline and has effects similar to LSD due to similarity in the structure and is the main psychoactive compound found in Claviceps Paspali and in (fresh) Heavenly Blue Morning Glory Seeds. LSH is unstable and breaks down into LSA quickly, so old seeds often only contains LSA and iso-LSA. When the seeds are fresh, they contain significantly higher amounts of LSH.

<span class="mw-page-title-main">Lysergic acid 2,4-dimethylazetidide</span> Chemical compound

Lysergic acid 2,4-dimethylazetidide (LA-SS-Az, LSZ) is an analog of LSD developed by the team led by David E. Nichols at Purdue University. It was developed as a rigid analog of LSD with the diethylamide group constrained into an azetidine ring in order to map the binding site at the 5-HT2A receptor. There are three possible stereoisomers around the azetidine ring, with the (S,S)-(+) isomer being the most active, slightly more potent than LSD itself in drug discrimination tests using trained rats.
