Is Mescaline legal in Saudi Arabia?

Legal status

Mescaline 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 «ميسكالين» under «الجدول الثاني... فئة (أ)», Schedule II Category A. The source cactus is dealt with separately: Schedule IV, the prohibited plants and seeds schedule, lists the mescal cactus and links it to this entry, so a live plant, a dried button and the isolated alkaloid are each reached by their own listing. That separation is worth keeping because it means neither the plant nor the alkaloid is being inferred from the other. 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 mescaline inside Article 37(I), and that article states no quantity at all. There is no weight threshold in it: 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 cultivation and extraction are both named limbs, which is how a grower and an extractor are reached as directly as a carrier. 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. Mescaline 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. Traditional or ceremonial use is not a recorded exemption in these schedules and none was found.

Documentation

There is nothing to carry for this substance, because no lawful import route was established for it, and that covers cactus material as well as the isolated alkaloid. 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 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.
