- The best review of this question is Rick Strassman's "Adverse Reactions
- to Psychedelic Drugs: a Review of the Literature" in _J. Nerv and Mental
- Disease_ 172(10):577-595. He writes:
-
- The most common adverse reaction is a temporary (less than 24 hours)
- episode of panic --the "bad trip". Symptoms include frightening illusions/
- hallucinations (usually visual and/or auditory); overwhelming anxiety
- to the point of panic; aggression with possible violent acting-out behavior;
- depression with suicidcal ideations, gestures, or attempts; confusion; and
- fearfulness to the point of paranoid delusions.
-
- Reactions that are prolonged (days to months) and/or require hospitalization
- are often referred to as "LSD psychosis," and include a heterogenous
- population and group of symptoms. Although there are no hard and
- fast rules, some trends have been noted in these patients. There is a
- tendency for people with poorer premorbid adjusment, a history of
- psychiatric illness and/or treatment, a greater number of exposure to
- psychedelic drugs (and correlatively, a great average total
- cumulative dosage taken over time), drug-taking in an unsupervised
- setting, a history of polydrug abuse, and self-therapeutic and/or
- peer-pressure-submission motive for drug use, to suffer these consequences.
-
- In spite of the impressive degree of prior problems noted in many of these
- patients, there are occasional reports of severe and prolonged reactions
- occuring in basically well adjusted individuals. In the same vein,
- there are many instance of faily poorly adapted individuals who suffer
- _no_ ill effects from repeated psychedelic drug use. In fact, it has been
- hypothesized that some schizophrenics do not suffer adverse reactions
- because of their familiarity with such acute altered states. Another
- possibility is that there individuals may be "protected" by possible "down-
- regulation" of the receptors for LSD, bu the (over-)production of some
- endogenous compound. _Individual_ prediction of adverse reactions,
- therefore, is quite difficult...

- Major "functional" psychosis vs. "LSD psychosis"
- -----------------------------------------------
-
- A diagnostic issue dealth with explicitly in only a few papers is that of
- LSD-precipitated major functional illnesses, e.g. affective disorders
- or schizophrenia. In other words, many of these so called LSD psychoses
- could be other illnesses that were triggered by the stress of a traumatic
- psychedelic drug experience. Some of the same methodological issues
- described earlier affect these studies, but they are, on the averagem
- better controlled, with more family and past psychiatric history available
- for comparison.
-
- Hensala et al. compared LSD-using and non-LSD-using psychiatric inpatients.
- They found that this group of patients was generally of a younger age and
- contained more characteristically disordered individuals than the non-
- LSD-using group. Patients with specific diagnoses with or without LSD
- histories were not compared. Based on their observations, they concluded
- that LSD was basically just another drug of abuse in a population of
- frequently hospitalized individuals in the San Francisco area, and that
- it was unlikely that psychedelic use could be deemed etiological in the
- development of their psychiatric disorders.
-
- Roy, Breakey et al., and Vardy and Kay have attempted to relate LSD use to
- the onset and revelopment of a schizophrenia-like syndrome. A few comments
- regarding this conceptual framework seem in order, before their findings
- are discussed. The major factor here is that of choosing schizophrenia,
- or in the Vardy and Kay study, schizophreniform disorders, as the
- comparison group. There is an implication here that LSD psychoses are
- comparable, phenomenologically, to schizophrenia-like disorders, and that
- LSD can "cause" the development of such disorders. The multiplicity of
- symptoms and syndromes described in the "adverse reaction" literature
- should make it clear that LSD can cause a number of reactions that can last
- for any amount of time--from minutes to, possibly, years. I believe what
- is being studied here is the question of the potential role of LSD in
- accelerating or precipitating the onset of an illness that was "programmed"
- to develop ultimately in a particular individual--in a manner comparable
- to the major physical or emotional stress that often precipitates a bona
- fide myocardial infarction in an individual with advanced coronary
- atheresclerosis. The stress did not _cause_ the heart disease; it was
- only the stimulus that accelerated the inexorable process to manifest
- illness.
-
- In looking at the relevant studies, Breakey et al. found that schizophrenics
- who "used drugs" had an earlier onset of symptoms and hospitalization than
- non-drug-using schizophrenics, and had possibly better premorbid personal-
- ities than non-drug using patients (although Vardy and KAy have challenged
- this analysis of Breakey's data).
-
- Bowers compared 12 first-admission patients with psychosis related to LSD
- use, requiring hospitalization and phenothiazines, to 26 patients hospital-
- ized and treated with phenothiazines with no history of drug use. Six
- of these controls had been previously hospitalized. Drug-induced psychotic
- patients were found to have better premorbib histories and prognostic
- indicators than the nondrug groups. There was no difference in rates of
- family history of psychiatric illness. However, several issues flaw
- this study. One is the poly-drug abusing nature of the "LSD-induced"
- psychotic patients, compared to the controls. The role of LSD, therefore,
- in causing or precipitating these symptomatic disorders, is open to dispute.
- The other is the lack of an adequate comparison control group, i.e. the
- controls were specified only as "psychotic," and did not necessarily
- match the LSD group in either symptoms or diagnostic classification.
- A follow-up study of the patients occured between 2 and 6 years later.
- One half did well and one half did poorly, although the lack of a control
- group for a follow-up in a similarly symptomatic control group makes
- interpretation of the data difficult.
-
- Roy, in a somewhat different design, compared chronic schizophrenic
- patients (diagnosed according to DSM-III criteria) who had used LSD
- within the week preceding hospitalization, and found no difference
- in age of symptom onset or hospitalization compared to patients without
- a history of illicit drug use.
-
- Vardy and Kay, in an elegant study with a 3- and 5- year follow-up period,
- demonstrated that patients hospitalized for a schizophrenic picture
- that developed within two weeks of LSD use (patients with other diagnoses
- were explicitly excluded form comparisons with non-drug-using
- schizophrenics) were "fundamentally similar to schizophrenics in
- geneology, phenomenology, and course of illness (165, p. 877). Pre-
- morbid adjustment, age of onset of symptoms and hospitalization, family
- history of psychosis or suicide, and most cognitive features were also
- equal between groups. Family histories of alcohol abuse were markedly
- great in the LSD group.
-
- I believe these data, taken as a whole, limited as they are in terms of
- comparing subgroups (i.e. LSD-using vs. non-LSD-using) of "schizophrenia-
- like" disorders, point towar, at most, a possible precipitory role in
- the development of these disorders, in a non specific and not
- etiologically related manner.

-
- So there you have it, folks.
-
- It's a good article, so rush out to the library and get it so you can
- appear knowledgable the next time someone at a cocktail party starts to
- talk about LSD turning people to vegetables. Nothing wins the
- admiration of potential mates like knowling references to _J. Nerv. Ment_
- and _Br. Med. J._!
