What is the Legal Status of LSD’s Analogs: 1P-LSD, 1A-LSD, and AL-LAD

1P-LSD, 1A-LSD (ALD-52), and AL-LAD are research chemicals which are analogs of LSD-25. As a result of their similarity to LSD-25, they are often used as substitutes in order to achieve comparable psychoactive effects. Due to their variations in molecular structure, each of these chemicals are treated somewhat differently from LSD-25 in legal systems around the world.

It's always a good idea to test your substance before using it. Buy reagent tests at Elevation Chemicals. Learn more about reagent testing for LSD and its analogs here at Explore Psychedelics.


The United States

In the United States, 1P-LSD falls within laws set forth by the Federal Analog Act.1 Because 1P-LSD has a chemical structure similar to LSD-25 and because 1P-LSD results in similar hallucinogenic effects as LSD-25, 1P-LSD and other “designer drugs” and “research chemicals” are liable to regulation, according to the Federal Analog Act.

Since substances fall under the Federal Analog Act’s umbrella only if an individual produces or possesses them with the intention to experience an effect on the central nervous system, 1P-LSD is sold with the accompanying label “not for human consumption.” This reduces the liability of sellers and buyers if subjected to scrutiny.1

Though the Federal Analog Act makes illegal production or possession of 1P-LSD with intent to consume, we found no cases of an American individual prosecuted for any reason related to 1P-LSD.


In Canada, on the other hand, 1P-LSD is entirely legal. One cannot be prosecuted for the purchase or possession of 1P-LSD2 since there is no mention of LSD analogs within Schedule III of the Controlled Drugs and Substances Act.3

A lawyer answered the question, “Would a small amount of 1P-LSD be seized by Canadian Border Services?” According to professional opinion, even if a small amount of an LSD-25 analog was seized, the courts would not find it illegal and a trial would result in exoneration of the accused party.4

European Union

Laws surrounding 1P-LSD differ from region to region within the European Union. In Germany, for example, 1P-LSD is not designated a controlled substance and is therefore legal on all accounts.2 Meanwhile, the United Kingdom’s Psychoactive Substances Act of 2016 deems it illegal to produce, distribute, or import 1P-LSD from other markets.5 1P-LSD is also illegal in Latvia and Sweden, while Austria’s NPSG (Neue-Psychoaktive-Substanzen-Gesetz Österreich) designates 1P-LSD an analog of LSD-25 which, similar to the United States, makes 1P-LSD illegal to produce or possess for the purpose of human consumption.6

1A-LSD (ALD-52)

Since there is much less information available regarding the legality of 1A-LSD, also known as ALD-52, this research chemical (like many others) falls into a legal gray area in most countries. As an LSD-25 analog, 1A-LSD may still find itself with similar legal confinements as 1P-LSD due to analog laws and restrictions.

United States

1A-LSD, like 1P-LSD, meets the three criteria required in order to be subject to the regulations of the Federal Analog Act:

  1. Its chemical structure is similar to a controlled substance (LSD-25).
  2. It has a psychoactive effect on the central nervous system similar to LSD-25.
  3. An individual can ingest it with the intention to achieve a psychoactive effect similar to LSD-25.1

Tim Scully and the Orange Sunshine Trial

Ever since Tim Scully was arrested in 1969 for producing LSD, it is a common misconception that he was producing 1A-LSD and was therefore incarcerated for producing an analog. This is not the case. Scully was indeed directly manufacturing LSD-257, and there are no other known cases of prosecution based on the production or possession of 1A-LSD.


No Canadian legislation exists which prevents the sale, consumption, possession, or distribution of 1A-LSD. Like 1P-LSD, 1A-LSD is considered an analog of LSD-25 and is therefore not listed as a controlled substance within the Controlled Drugs and Substances Act.3

European Union

In 2014, 1A-LSD was recommended for addition to the Misuse of Drugs Act and is now considered an illegal Schedule I drug in the United Kingdom.289 In Latvia, 1A-LSD has been illegal since 2015, when an amendment was introduced to classify 1A-LSD as an analog of LSD-25.10 Like 1P-LSD, 1A-LSD may be deemed an illegal analog in accordance with the NPSG.11


AL-LAD is subject to the same laws as 1A-LSD. In other words, it may be considered illegal as an analog due to the Federal Analog Act of the United States, the United Kingdom’s Misuse of Drugs Act, Austria’s NPSG, and the 2015 legislative amendment in Latvia. In Sweden, AL-LAD was classified as a drug and made illegal in 2016.12


While LSD analogs currently have a quasilegal status in the United States, a new bill called Stop the Importation and Trafficking of Synthetic Analogues (SITSA) Act threatens to make even the research use of LSD analogs illegal in the United States. The bill has passed the House, and may pass the Senate. We will be closely monitoring its status. 13
