1. The somatic phase occurs after absorption of the drug & consists of CNS stimulation & autonomic changes that are predominantly sympathomimetic in nature.
2. The sensory (or perceptual) phase is characterized by sensory distortions and pseudohallucinations, which are the desired effects by the drug user.
3. The psychic phase signals a maximum drug effect, with changes in mood, disruption of thought processes, altered perceptions of time, depersonalization, true hallucinations, and psychotic episodes. Experiencing this phase is called a “bad trip”.
