Is 1P-LSD legal in Saudi Arabia?

Legal status

Not established, and the search that failed is recorded rather than summarised. The schedules attached to the Law of Combating Narcotics and Psychotropic Substances, Royal Decree M/39 of 1426 AH, in the version issued on 4 September 2026, were searched from Schedule I to Schedule IV for 1P-LSD and no matching entry was verified. The search record reads «سجل البحث الخاص بـ 1p-lsd: فُحصت الجداول من الأول إلى الرابع ولم يُتحقق من قيد مطابق.», the item specific search record for 1P-LSD, the schedules from the first to the fourth were examined and no matching entry was verified. What was searched: “1P-LSD”, “1-propionyl-LSD”, “1-propionyllysergide”, «1P-LSD»; the LSD and lysergide entries, the lysergamide entry and the isomer and ester clauses were all checked, and no exact N-propionyl entry was found. LSD itself is expressly scheduled at Schedule II Category A and lysergamide at Schedule II Category E, so the neighbouring entries exist and were read; neither of them is 1P-LSD, and the isomer and ester wording that was checked did not carry either of them to it. Absence of a verified entry is not a finding that the substance is lawful in Saudi Arabia. The schedules are kept current under M/39 Articles 70 to 71 rather than by a fresh Royal Decree, so an entry can appear without the Law changing.

Consequences if caught

Capital exposure: none. That records what this pass established for 1P-LSD and not how a Saudi court would treat a blotter. Article 37(I) is the capital route in M/39, it carries no quantity threshold of any kind, and its death sentence is reducible by the court under Article 37(II) to a prison term of not less than fifteen years with the stated lashes and fine. None of that is assigned to this row, because the exact Schedule I or Schedule II entry, or a qualifying Schedule IV reach, was not verified for 1P-LSD. No weight can cure an identity gap: there is no quantity at which an unlisted compound becomes a listed one, and none below which a listed one escapes Article 37. The practical hazard on this row is a chemical one rather than a legal one, because a blotter sold as 1P-LSD that in fact carries LSD is a Schedule II Category A article and the Article 37 route opens on that constituent.

If prescribed or medical

The Saudi traveller rule is a permit rule rather than a prescription rule. A controlled medicine may be brought in only under a clearance obtained from the SFDA before travel through its Controlled Drugs System, and that advance electronic clearance is required rather than optional. A foreign prescription is not a Saudi clearance. For 1P-LSD the schedule placement that would normally be attached to that rule was not established, so it cannot be attached here, and which permit category a 1P-LSD preparation would fall into is deferred rather than answered. No Saudi dispensing route and no medicinal product containing 1P-LSD was recorded.

Documentation

There is nothing to carry for this substance, because no lawful import route was established for it. For any controlled medicine, apply through the SFDA Controlled Drugs System before travelling, carry the clearance and not the prescription alone, bring the medicine in its original dispensing packaging with the prescription and a medical report translated into Arabic and dated less than six months before travel, keep to a one month supply or the length of the stay, and declare it at customs; advance electronic clearance has been required since 1 November 2025. The permit mechanics stated here are the SFDA traveller rules recorded on the current live cell and were not re-derived from the instrument in this pass. The failed schedule search for 1P-LSD was run against the 4 September 2026 schedules on 17 September 2026 and is recorded above so that a later reader can repeat it rather than restate it.

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