PRO-LAD

PRO-LAD, or PROLAD, also known as 6-propyl-6-nor-LSD, is a psychedelic drug of the lysergamide family related to lysergic acid diethylamide. It is taken orally.

Use and effects

According to Alexander Shulgin in his book TiHKAL and other publications, PRO-LAD has a dose range of 100 to 200μg or 80 to 175μg orally and a duration of 6 to 8hours. The onset is within 15minutes. It has around the same potency as LSD, which has a listed dose range of 50 to 200μg. On the other hand, PRO-LAD has a shorter duration than LSD, which has a listed duration of 8 to 12hours.
The effects of PRO-LAD have been reported to include a lack of visuals and other psychedelic effects at lower doses, considerable visuals at higher doses, fantasy, synesthesia, clear thinking, lack of "cosmic-type" thinking, humor, pleasantness, dulled emotions, uncomfortableness, paranoia, and lightheadedness. It has been described as having relatively light or moderate effects. In addition, it is said to "not have any of the flavor of LSD", to be less visual than LSD, and to be "not up to LSD", if that is one's standard, as it is "basically not like LSD".

Interactions

Pharmacology

Pharmacodynamics

PRO-LAD shows affinity for serotonin receptors, including for the serotonin 5-HT_1A, 5-HT_2A, and 5-HT_2C receptors. It acts as a partial agonist of the serotonin 5-HT_2A receptor similarly to LSD.
The drug fully substitutes for LSD in rodent drug discrimination tests and with about the same or slightly greater potency than LSD itself. On the other hand, it was about 2- to 3-fold less potent than ETH-LAD or AL-LAD.

History

PRO-LAD was first described in the scientific literature by Tetsukichi Niwaguchi and colleagues in 1976. Subsequently, it was studied and described by Andrew J. Hoffman and David E. Nichols in 1985. The hallucinogenic effects of PRO-LAD in humans were first described by Nichols in a literature review via personal communication with Alexander Shulgin in 1986. The drug was later described in greater detail by Shulgin in his 1997 book TiHKAL. PRO-LAD is said to have been encountered as a novel designer drug by 2015.

Society and culture

The UK Home office accepted this advice and announced a ban of the substance to be enacted on 6 January 2015 as part of .
