Abstract
This research essay/article argues that cannabis can reasonably be described as psychedelic in a phenomenological sense, even though it is not pharmacologically classified as a classic serotonergic psychedelic such as LSD or psilocybin. The central distinction is between pharmacology and phenomenology: THC acts primarily through the endocannabinoid system, especially CB1 receptor signaling, yet can produce marked alterations in time perception, salience, association, self-reference, emotional intensity, sensory experience, introspection, and, in some users, mystical or self-transcendent states. The essay reviews this altered-state profile alongside evidence for established therapeutic uses of cannabis and cannabinoids, including chronic pain, chemotherapy-associated nausea and vomiting, multiple-sclerosis spasticity, and specific seizure disorders. It also considers the plant’s entheogenic history, spiritual-use literature, context sensitivity, and the role of set and setting in shaping subjective effects. At the same time, the paper addresses important risks, including anxiety, cognitive impairment, impaired driving, cannabis use disorder, psychosis vulnerability, and withdrawal-related complications. The resulting position is neither pure cannabis romanticism nor total prohibitionist dismissal. Cannabis is presented as a pharmacologically atypical, phenomenologically psychedelic, medically useful in several established contexts, psychologically intriguing in others, and highly dependent on dose, individual biology, neurology, expectations/biases, environment, and pattern of use.
