Acid is cut with strychnine, and that is what gives you the body load.
A blotter square weighs about 2 mg, too little to hold an active dose of strychnine, and the street-drug labs that tested LSD did not report finding it. The one documented case is a powder sold as LSD in the late 1960s.
First documented: , Acid Dreams by Martin Lee and Bruce Shlain, page 188, as cited by a reader to Ask Erowid
Origin, evidence and 4 references
Origin
There is one documented case behind the story. In his book LSD: My Problem Child, Albert Hofmann described "a case in the late sixties of strychnine being found in an LSD sample that was a white powder".[1]
By 1985 the claim was in print as history. Acid Dreams, by Martin Lee and Bruce Shlain, blamed part of the decline of Haight-Ashbury on "samples of LSD showing up laced with amphetamines and strychnine". Erowid later noted the authors gave no source, and filed the claim as a myth "without a reference or additional data to back it up".[2]
On Usenet it was already a running argument. A 1992 post to alt.drugs said "the most likely place to find strychnine is in myths posted to alt.drugs".[1]
The evidence
The chemist Alexander Shulgin wrote that he had looked at a large number of illicit street samples and "never detected the presence of strychnine" in them. He added that "strychnine is not needed to bond LSD to blotter paper", and that it is not a breakdown product of LSD either.[1]
Street-drug testing programs agree. Published analyses by PharmChem and the Los Angeles County street drug analysis program are described as ones "which likewise never found any strychnine".[1] George Root, who ran Florida's anonymous street drug testing program from 1972 to 1977, wrote: "I recall no instances of samples of actual LSD being combined with strychnine".[1]
The arithmetic rules it out for blotter. A standard 5 mm square weighs about 2 mg. Even "if the paper itself was made completely out of pure strychnine", the dose would sit at the very bottom of its range of activity.[1] Erowid puts it plainly: "It is virtually impossible to fit enough strychnine to have any effect" in most LSD preparations.[3] The 1960s were different only in form, since then "LSD was sold primarily in tablet form" and a tablet is easier to fake.[2]
Strychnine does turn up as an adulterant, in other drugs. A 2011 review of adulterant studies lists it in heroin and notes that the amounts found, "such as strychnine in heroin, are not life-threatening".[4]
The body load has other explanations. Cramps and nausea are reported with LSD itself, and "poorly synthesized LSD might have other ergot derivatives in it".[1]
