1D-LSD, scientifically known as 1-(1,2-dimethylcyclobutane-1-carbonyl)-lysergic acid diethylamide, is a psychotropic compound classified as a research chemical. It is recognized for its potential to induce psychedelic effects. It is theorized to act as a prodrug for LSD, undergoing metabolic conversion to LSD within the body. Notably, 1D-LSD has replaced 1V-LSD in Germany following the inclusion of 1V-LSD within the scope of the German NpSG law in 2022. Additionally, it is available in a tartrate form.

Currently, 1D-LSD falls outside the regulatory scope of the German BTMG (Narcotics Act) and the NpSG law (New Psychoactive Substances Act). Consequently, it can legally be distributed and used for research purposes within Germany.


Per the current legal framework, 1D-LSD is not explicitly listed in the Narcotic Drugs Ordinance or the Psychotropic Substances Ordinance (SV/PV). Therefore, within the Austrian legal context, it does not qualify as a controlled narcotic substance under SV or a psychotropic compound under PV.


1. What is 1D-LSD?

  • 1D-LSD, or 1-(1,2-dimethylcyclobutane-1-carbonyl)-lysergic acid diethylamide, is a chemical compound classified as a research chemical. It is known for its potential to produce psychedelic effects.

2. Is 1D-LSD legal in Germany?

  • As of the current regulations, 1D-LSD is not covered by either the German Narcotics Act (BTMG) or the New Psychoactive Substances Act (NpSG). Therefore, it can be legally obtained and used for research purposes within Germany.

3. What is the legal status of 1D-LSD in Austria?

  • In Austria, 1D-LSD is not explicitly mentioned in the Narcotic Drugs Ordinance or the Psychotropic Substances Ordinance (SV/PV). Consequently, Austrian law does not classify it as a narcotic drug under SV or as a psychotropic substance under PV.

4. Can 1D-LSD be used for research purposes?

  • Yes, 1D-LSD is commonly used for research purposes, particularly in psychedelic studies. Researchers may use it to investigate its effects and potential therapeutic applications.

5. What are the potential effects of 1D-LSD?

  • 1D-LSD is believed to have psychedelic effects similar to those of LSD. Users may experience alterations in perception, mood, and consciousness, visual distortions, and thought patterns.

6. Is 1D-LSD safe to use?

  • The safety of 1D-LSD is not well-established, as research on this specific compound is limited. As with all research chemicals and psychedelics, caution and responsible use are essential. Users should be aware of potential risks and take appropriate measures to minimize harm.

7. Can 1D-LSD be detected in drug tests?

  • Standard drug tests typically do not screen for 1D-LSD precisely. However, it is essential to note that the legality and detection of substances can vary by jurisdiction and testing methods.

8. What is the chemical structure of 1D-LSD?

  • 1D-LSD’s chemical structure includes a lysergic acid diethylamide (LSD) core with a cyclobutane-1-carbonyl group attached, making it a derivative of LSD.

9. Where can I obtain 1D-LSD for research purposes?

  • The availability of 1D-LSD may vary by region and local regulations. Researchers typically source it from reputable chemical suppliers that cater to scientific research needs.

10. Are there any potential therapeutic applications for 1D-LSD?

  • Research on the therapeutic potential of 1D-LSD is ongoing, but it is currently not approved for any medical or therapeutic use. Scientists are exploring various psychedelics, including 1D-LSD, for potential mental health and psychotherapy applications.

Remember that 1D-LSD, like other research chemicals and psychedelics, should be handled responsibly and by applicable laws and regulations. Researchers should prioritize safety and ethical considerations in their work.
