Is LSD legal in Saudi Arabia?

Legal status

LSD is a controlled psychotropic substance in Saudi Arabia, placed at Schedule II Category A of the schedules attached to the Law of Combating Narcotics and Psychotropic Substances, Royal Decree M/39 of 1426 AH, in the version of those schedules issued on 4 September 2026. The schedule prints «ليسرجيد», lysergide, under «الجدول الثاني... فئة (أ)», Schedule II Category A. The entry is for lysergide itself, which is why the related rows in this table sit where they do: 1P-LSD was searched against this entry and the isomer and ester clauses and could not be matched, while lysergamide has its own separate Category E entry. An entry for one lysergamide is not an entry for every lysergamide, and the Kingdom's schedules treat them as distinct. M/39 Articles 1 and 70 to 71 are cited for identification and for keeping the attached schedules current.

Consequences if caught

A Schedule II Category A placement puts LSD inside Article 37(I), and that article states no quantity at all. The absence of a threshold is worth dwelling on here, because LSD is dosed in micrograms and a sheet of blotter weighs almost nothing: the conduct named is smuggling, receipt from a smuggler, and import, export, manufacture, production, extraction or cultivation with intent to promote, together with the repeat promotion histories the article sets out, and none of it turns on mass. Death under Article 37(I) is a statutory ta'zir penalty and it is not mandatory, because Article 37(II) gives the court the power to reduce it; where the court does reduce, the substitute is a prison term of not less than fifteen years with the lashes and the fine the article states. No express life imprisonment wording was found anywhere in M/39. Articles 38 to 41 are cited as the tiers below Article 37.

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. LSD sits inside that regime as a Schedule II Category A substance, and no Saudi dispensing route and no medicinal product containing it was recorded, so nothing here should be read as saying a clearance would issue for it. Participation in a clinical trial elsewhere is not a Saudi authorisation.

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, 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 Schedule II Category A placement for lysergide was read in the 4 September 2026 schedules on 17 September 2026.

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.
