"With regard to effectiveness, both orientations have reported impressive results. Since over three-hundred studies have been reported, only the most salient and consistent findings will be summarized. Despite great diversity in the conduct of these studies, high improvement rates have been almost uniformly reported, with both adults and children, and in group as well as individual psychotherapy. Used either as an adjunct or as a primary treatment method, LSD has been found to facilitate improvement In patients covering the complete spectrum of neurotic, psychosomatic, and character disorders. Particularly noteworthy are the positive results obtained with cases highly resistant to conventional forms of therapy. High remission rates among alcoholics, for example, have frequently been reported following a single, large dose LSD session. Based on their findings with over one-thousand alcoholics, Hoffer and his co-workers concluded that LSD was twice as effective as any other treatment program (1965). Other chronic conditions carrying a poor prognosis which have responded favoi ably to psychedelic therapy include sexual deviations, criminal psychopathy, autism in children, and adolescent behavior disorders.
Since most reports have been based on clinical judgements of unknown reliability, it is worth noting that comparable results have been obtained by investigators in many other countries. Furthermore, Freudian therapists, Jungians, behaviorists, existentialists, and a variety of eclectic therapists have reported positive findings with LSD. It seems safe to conclude from the breadth and consistency of the clinical evidence that LSD can produce far-reaching beneficial effects in some people, under some conditions. " 
Comments on the nature of LSD.
What, then, should be done about it? LSD is certainly one of the least toxic chemicals man has ever put inside his system. Compared with alcohol, nicotine, coffee - our three great stand-bys - it could be called almost a docile mare as against these mettlesome stallions, s? far as most people are concerned. Is it of any use with psychotics? Most researchers doubt it. With the extreme neurotic? Again there seems to be considerable question. Although among these categories LSD appears to do no physical harm, cases of severe adverse psychological effects have been reported. It is the unique quality of attention which LSD can bestow that will or will not be of benefit. Intensity of attention is what all talented people must obtain or command if they are to exercise their talent. Absolute attention - as we know from, for example, Isaac Newton's and Johann Sebastian Bach's descriptions of the state of mind in which they worked - is the most evident mark of genius functioning. On the other hand, the masterful Sigmund Freud remarked that psychoanalysis, even when exercised by himself, would not work with the extreme neurotic because of the hypertrophied ego-attention which such a patient had sacrificed his life to build up. The psychotic is even more absorbed in his distortive, self-obsessed notion of reality. Give, then, either of these victims of their own egos still greater capacity to attend, and it is highly unlikely that they will do other than dig still more deeply the ditch of their delusion and build more stubbornly the wall of their self-inflicted prison. But for the truly creative person (and I refer specifically to that person capable of exercising "integral thought") LSD may be of some use. It could help him to exercise integral thought with greater ease and facility, and at will. And for a number of sensitive people willing to present themselves for a serious experiment in depth, LSD has shown itself of some help in permeating the ego, in resolving emotional conflicts, and in reducing those basic fears, the ultimate of which is the fear of death.
