Chicago, Astor St. Illinois 60610 Dear Dr. Gibbs: Your recent EEG, I: editorial (Clinicalw 127) asserts that "cannabis indica produces no marked or consistent changes in the EEG" md ". .. the changes they [psychotomimetic drugs] produce in the electrical activity of the cortex are of the same minor order as are produced by tobacco“. It is difficult to see how you can arrive at such sweeping conclusions, based on the data printed. The report by Deliyannakis et a1. finds large effects of cannabis, in a few subjects, with equipment of limited frequency response. They make no effort at quantification and we have no idea about the sample size, stability over time, artefact control, Despite the limitations of equipment and technique, filtering, etc. they report large changes, albeit not in every subject. In numerous studies of the EEG effects of heroin, LSD, major changes have been observed and related to drug dosage, pro-existing EEG and clinical effects (for examples, see Ann. Rev. Pharmacology, 9:241—258,1969; Neuropharnacology, 9:539,1970). Such studies show that large EEG Changes are common, drug and dose related, and interestingly related to the behavior of the subject. Considering the major strides made in quantitative EEG, it does neither the science of EEG nor clinical practice a service to make such sweeping assertions as "Let's face it, disordered psychic function, either spontaneous or drug induced, commonly does not correlate with major abnormalities in the waking electroencephalogram". �Dr. Gibbs ~2- February 26, 1971 Years ago we looked at the moon and saw a fairly flat surface with a few ridges. With better tools. it became obiious that the ridges, mountains and valleys were substantial. How substantial was recently demonstrated by the astronauts limited ability to climb a small ridge. The sruface EEG is not a homogeneous, insensitive flat serface, but a sensitive, ever-changing reflection of mood, memory, and alertness. use them. Our tools Particularly, do decode differences already, were we to were we to look carefully, with the tools of the 1970': not those of the 1940’s. Sincerely yours, Max Fink, “.0.
