AL-LAD, also known as 6-allyl-6-nor-LSD, is a psychedelic drug and an analog of lysergic acid diethylamide (LSD). It is described by Alexander Shulgin in the book TiHKAL (Tryptamines i Have Known And Loved). It is synthesized starting from LSD as a precursor, using allyl iodide as a reactant.

Effects in humans

AL-LAD on blotter paper

While AL-LAD has subtly different effects than LSD, and appears to be slightly shorter lasting, their potencies are similar;[1] an active dose of AL-LAD is reported to be between 80 and 160 micrograms.[2] AL-LAD has a known but short and highly uncommon history of recreational human use, which originated in Ireland and the UK, but spread internationally.


AL-LAD does not cause a color change with the Marquis, Mecke or Mandelin reagents,[3] but does cause the Ehrlich's reagent to turn purple because of the presence of the indole moiety in its structure.

Legal status

On June 10th 2014 the UK Advisory Council on the Misuse of Drugs (ACMD) recommended that AL-LAD be specifically named in the UK Misuse of Drugs Act as a class A drug despite not identifying any harm associated with its use.[4] The UK Home office accepted this advice and announced a ban of the substance to be enacted on 6 January 2015 as part of The Misuse of Drugs Act 1971 (Amendment) (No. 2) Order 2014.
