Dextromethorphan (DXM) is an OTC cough suppressant.
In larger doses it becomes a dissociative hallucinogen, which produces effects similar to drugs such as ketamine, nitrous oxide, and phencyclidine (PCP).
Effects may include:
- distortions of the visual field
- feelings of dissociation
- distorted bodily perception
- a loss of sense of time
- stimulant-like euphoria
Dextromethorphan effects are often described as four stages, or “plateaus:”
- At lower doses (1.5 to 2.5 mg per kg body weight): music euphoria and mild stimulation, likened to that of MDMA.
- With increasing doses (2.5 to 7.5 mg/kg), one may reach a state similar to being drunk and high at the same time, along with euphoria, sedation, and closed-eye hallucinations.
- The third plateau is characterized by a significant dissociative state, out-of-body experiences, and sometimes anxiety.
- The most intense effects are extreme sedation, a significant hallucinatory state, as well as complete dissociation from reality.
