Is 1P-LSD legal in Spain?

Legal status

Not a controlled substance on the text read: 1P-LSD is not named in Anexo 1 or Anexo 2 of Real Decreto 2829/1977, and it is not in the 1961 Convention lists that Ley 17/1967 article 2 incorporates. Search log: «1P-LSD» returned 0 whole word hits in Anexo 1, 0 in Anexo 2 and 0 in the Yellow List; «propionil» returned 0 whole word hits in Anexo 1, 0 in Anexo 2 and 1 in the Yellow List (0, 0 and 6 counting it inside longer words). Nor is it in the 1971 Convention schedules as printed in the English INCB Green List, 36th edition, 2025: «1P-LSD» returned 0 whole word hits there. The nearest entry, LSD at Lista I entry 11, is defined as «(+)-N, N-dietilisergamida»; 1P-LSD is its 1-propionyl derivative and is not printed. The Yellow List whole word hit for «propionil» is BECITRAMIDA, «1-(3-ciano-3,3-difenilpropil)-4-(2-oxo-3-propionil-1-bencimidazolinil)», an opioid, not a lysergamide. The psychotropic annexes are a closed enumerated list: the stems «análog» and «isómer» return 0 and 1 hits across both annexes, the one «isómer» hit being zipeprol's own entry covering its stereoisomers, so there is no analogue or generic clause. A substance enters only when a later instrument adds its name: article 1 extends the decree to substances «o bien que en futuro puedan ser incorporadas a las Listas o la Relación», ministerial orders have amended Anexo 1, and article 4 lets the Dirección General amend Anexo 2 «mediante Resolución, podrá modificar el contenido de la Lista de principios activos contenidos en el anexo dos» (may, by resolution, amend the list of active ingredients in annex two). The lists are read as at the Real Decreto 2829/1977 consolidation published 21/04/2026 and in force from 22/04/2026. Narcotic absences are decided through Ley 17/1967 article 2 against the INCB Yellow List, 65th edition of July 2026; the INCB Green List, 36th edition updated December 2025, is a cross-check for psychotropics. Narcotics can also be designated nationally, «en el ámbito nacional por el procedimiento que reglamentariamente se establezca» (nationally, by the procedure set by regulation); Real Decreto 1194/2011 sets that procedure and so far names tapentadol and isotonitaceno, as consolidated to 8 June 2021. 1971 Convention decisions after December 2025 and 1961 Convention decisions after July 2026 were not read, and this does not rule out a later amendment.

Consequences if caught

Because no list names it, Código Penal article 368 and Ley Orgánica 4/2015 article 36.16 are not reached through a list entry. Article 368 also uses the undefined term «drogas tóxicas»; whether a court could treat an unlisted substance as one is not determined in this cell, and no instance of it for this substance was read. Neighbouring penal law searched: Código Penal article 359 punishes whoever «sin hallarse debidamente autorizado, elabore sustancias nocivas para la salud o productos químicos que puedan causar estragos, o los despache o suministre, o comercie con ellos» with «prisión de seis meses a tres años y multa de seis a doce meses». Whether a given product is a substance harmful to health in that sense was not determined, and no application of the article to this substance was read.

If prescribed or medical

Spain runs two medicine control regimes side by side: narcotic medicines under Ley 17/1967 and psychotropic medicines under Real Decreto 2829/1977. No prescription route is stated: no drug list reaches it, and no Spanish medicine authorisation for it was read for this cell.

Documentation

No travel document regime applies to it as a drug. Customs and product rules for the goods themselves were not read for this cell.

Drug laws and enforcement change and vary within a country. This is not legal advice. Always confirm with Spain’s embassy or official drug authority before traveling; penalties can be severe, including imprisonment.
