Shulgin Rating Scale

Last updated

The Shulgin Rating Scale (or "quantitative potency scale") is a simple scale for reporting the subjective effect of psychoactive substances at a given dosage, and at a given time. The system was developed for research purposes by the American biochemist Alexander Shulgin, and published with co-authors Ann Shulgin and Peyton Jacob, III, in a 1986 issue of the journal Methods and Findings in Experimental and Clinical Pharmacology. It was later described in the Shulgins' popular 1991 book PIHKAL: A Chemical Love Story. [1]

Usage

Shulgin Ratings typically include three components. An identification of the chemical being ingested, a dosage, and a descriptive narrative including the ratings themselves used to describe various moments in time. The chemical itself must be clearly identified, preferably using chemical nomenclature, as opposed to popular or "street" names. The dosage must be known and communicated, as substances may result in wildly different ratings at different doses. The rating itself gives a comparable value relating to the subjective intensity of the experience, including auditory, visual, emotional, mental, physical and other sensory effects. The narrative may include various Shulgin ratings, noting the time to achieve various levels, for instance:

(with 22 mg) A slow onset. It took an hour for a plus one, and almost another two hours to get to a +++. Very vivid fantasy images, eyes closed, but no blurring of lines between "reality" and fantasy. Some yellow-grey patterns a la psilocybin. Acute diarrhea at about the fourth hour but no other obvious physical problems. Erotic lovely. Good material for unknown number of possible uses. Can explore for a long time. Better try 20 milligrams next time.

PIHKAL, page 560, in regards to the substance 2C-T-2

Potential PLUS FOUR, n. (++++) candidate substance

5-MeO-DMT is a candidate entheogen substance for consistent plus four experience as it is known to bring one if the not the highest mystical subjective experience comparable to the description of Samadhi. [2] [3]

Alexander Theodore "Sasha" Shulgin was an American medicinal chemist, biochemist, organic chemist, pharmacologist, psychopharmacologist, and author. He is credited with introducing MDMA, commonly known as "ecstasy", to psychologists in the late 1970s for psychopharmaceutical use and for the discovery, synthesis and personal bioassay of over 230 psychoactive compounds for their psychedelic and entactogenic potential.

<i>PiHKAL</i> 1991 book by Alexander Shulgin and Ann Shulgin

PiHKAL: A Chemical Love Story is a book by Dr. Alexander Shulgin and Ann Shulgin, published in 1991. The subject of the work is psychoactive phenethylamine chemical derivatives, notably those that act as psychedelics and/or empathogen-entactogens. The main title, PiHKAL, is an acronym that stands for "Phenethylamines I Have Known and Loved."

<span class="mw-page-title-main">2C-B</span> Chemical compound

2C-B (4-bromo-2,5-dimethoxyphenethylamine) is a synthetic psychedelic drug of the 2C family, mainly used as a recreational drug. The substance was first synthesized by Alexander Shulgin in 1974, and gained an initial reputation for potential psychotherapeutic use, but its use has been limited to mainly recreational use. To date, there is limited scientific information regarding the drug's pharmacokinetics and pharmacological effects in humans. The existing studies primarily classify 2C-B as a stimulant, and hallucinogen, and less commonly as an entactogen, and empathogen.

<span class="mw-page-title-main">2C-T-7</span> Psychedelic phenthylamine drug

2C-T-7 is a psychedelic phenethylamine of the 2C family. In his book PiHKAL: A Chemical Love Story, Alexander Shulgin lists the dosage range as 10–30 mg. 2C-T-7 is generally taken orally, and produces psychedelic and entactogenic effects that last 8 to 15 hours. Up until Operation Web Tryp and three deaths, two of which involved the use of other drugs in addition to 2C-T-7, and one which involved an excessive insufflated dose, 2C-T-7 was sold commercially in Dutch and Japanese smartshops and online. It is known on the streets as Blue Mystic or 7th Heaven. There has been little real research done on this chemical other than Shulgin's comments in PiHKAL and a few small animal studies mostly aimed at detecting metabolites.

Lophophine is a putative psychedelic and entactogen drug of the methylenedioxyphenethylamine class. It is the α-demethylated homologue of MMDA, and is also closely related to mescaline.

<span class="mw-page-title-main">Aleph (psychedelic)</span> Chemical compound

Aleph is a psychedelic hallucinogenic drug and a substituted amphetamine of the phenethylamine class of compounds, which can be used as an entheogen. It was first synthesized by Alexander Shulgin, who named it after the first letter of the Hebrew alphabet. In his book PiHKAL, Shulgin lists the dosage range as 5–10 mg, with effects typically lasting for 6 to 8 hours.

<span class="mw-page-title-main">EDMA</span> Chemical compound

3,4-Ethylenedioxy-N-methylamphetamine (EDMA) is an entactogen drug of the methamphetamine class. It is an analogue of MDMA where the methylenedioxy ring has been replaced by an ethylenedioxy ring. EDMA was first synthesized by Alexander Shulgin. In his book PiHKAL, the dosage is listed as 150–250 mg, and the duration listed as 3–5 hours. According to Shulgin, EDMA produces a bare threshold consisting of paresthesia, nystagmus, and hypnogogic imagery, with few to no other effects. Scientific research has demonstrated that EDMA acts as a non-neurotoxic serotonin releasing agent with moderately diminished potency relative to MDMA, and with negligible effects on dopamine release.
