Psychedelic therapy occupies a contested and generative position within the depth-psychology corpus, appearing most fully elaborated in the extensive clinical writings of Stanislav Grof and finding renewed theoretical grounding in the work of Mahr, Carhart-Harris, and Strassman. The corpus reveals two principal lineages of debate. The first concerns the distinction between psycholytic therapy — involving repeated low doses of LSD within a largely psychoanalytic frame — and the high-dose psychedelic approach, which cultivates peak or transcendent experiences capable of precipitating rapid, wholesale personality transformation. Grof's sustained argument is that the latter modality, by facilitating perinatal and transpersonal states rather than suppressing them as psychotic artifacts, accesses dimensions of the unconscious foreclosed to conventional analysis. The second tension concerns theoretical adequacy: Jungian frameworks, largely neglected by mainstream psychedelic researchers since the 1970s, are rehabilitated by Mahr and Sweigart as uniquely suited to the archetypal phenomenology of hallucinogenic experience. Carhart-Harris contributes a neurodynamic account grounded in entropic brain theory, while Strassman emphasizes therapist preparation in theological, relational, and phenomenological domains. Across the corpus, psychedelic therapy functions not merely as a clinical technique but as a catalyst for rethinking the architecture of the psyche itself.

If we consider the other important advantages of psychedelic therapy, such as reduced time investment, less intense exposure to the drug, and fewer transference problems, it would seem that the psychedelic procedure is clearly superior to the psycholytic approach.
Grof argues that the high-dose psychedelic approach holds structural advantages over psycholytic therapy but cautions that its rapid transformations may represent temporary rather than structurally deep change.

If we consider the other important advantages of psychedelic therapy, such as reduced time investment, less intense exposure to the drug, and fewer transference problems, it would seem that the psychedelic procedure is clearly superior to the psycholytic approach.
Grof's comparative analysis of psychedelic versus psycholytic therapy identifies therapeutic efficiency as a key advantage of the former while flagging the epistemological problem of distinguishing genuine structural change from temporary remission.
Grof, Stanislav, LSD Psychotherapy: Exploring the Frontiers of the Hidden Mind, 1980thesis
Within the psycholytic framework, transpersonal phenomena are not acknowledged and their therapeutic value is not recognized. Patients are thus implicitly or explicitly discouraged from entering transcendental states.
Grof demonstrates that the psycholytic approach actively suppresses the very transpersonal states that psychedelic therapy regards as the primary locus of deep healing.

Psychedelic drugs appear to provide access to unconscious material and, when used in a therapeutic context, may cause deep and longstanding psychological change. The psychological effects of psychedelic drugs are reviewed from the perspective of Jungian theory.
Mahr and Sweigart argue that Jungian depth psychology offers an underutilized but theoretically appropriate framework for interpreting the archetypal and unconscious dimensions activated in psychedelic therapy.
Mahr, Greg, Psychedelic Drugs and Jungian Therapy, 2020thesis
Many psychiatrists working with psychedelics in the 1950s and 60s expressed great enthusiasm about their therapeutic potential but there was an unfortunate failure to substantiate these beliefs with properly controlled studies.
Carhart-Harris situates the contemporary revival of psychedelic therapy against the historical failure to produce rigorous empirical validation, while arguing that neuroimaging evidence now supports the therapeutic promise.

An ideal course of LSD psychotherapy involves an open-ended situation in which the number of sessions is not limited a priori. In general, the treatment process consists of three separate but mutually interrelated phases.
Grof articulates the structural principles of LSD psychotherapy — preparation, psychedelic session, and integration — as a tripartite protocol whose open-ended nature distinguishes it from time-limited clinical interventions.

Some psychedelic therapists therefore tend to include elements of Oriental and primitive art in the interior decoration of their treatment rooms. The art objects used in this context range from Hindu and Buddhist sculptures, paintings and mandalas, Pre-Columbian ceramics and Egyptian statuettes to African tribal art.
Grof describes the intentional construction of a symbolically saturated ceremonial setting in the psychedelic approach, aligning therapeutic space with cross-cultural sacred iconography to facilitate transpersonal experience.

In some patients, LSD psychotherapy can lead to dramatic improvement of certain recalcitrant physical problems that are traditionally considered organic in origin; certain chronic infections such as cystitis, bronchitis, and sinusitis are examples of this.
Grof extends the scope of psychedelic therapy to somatic healing, arguing that the resolution of psychological gestalts in LSD sessions can precipitate improvement in physical conditions previously classified as purely organic.

Very little systematic and serious attention was given to a variety of phenomena that have been described over centuries within the framework of the world's great religions, as well as temple mysteries, mystery religions, initiation rites, and various mystical schools.
Grof's early observations from LSD psychotherapy identify its primary contribution as opening scientific access to transpersonal phenomena previously relegated to religious and esoteric traditions.

The dosages used in this treatment technique ranged between 100 and 200 micrograms of LSD, sometimes with the addition of Ritalin in later hours of the sessions. Martin and McCririck described good and relatively rapidly achieved results in patients with deep neuroses or borderline psychotic disorders who had experienced severe emotional deprivation in childhood.
Grof documents the anaclitic technique as a specialized form of psychedelic therapy designed to address early object-relational deficits through the regression and reparative contact facilitated by the drug state.
