Recreational Use
Since their introduction, over-the-counter preparations containing dextromethorphan have been used in manners inconsistent with their labeling, often as a recreational drug. At doses much higher than medically recommended, dextromethorphan is classified as a dissociative hallucinogen, possessing certain effects that are somewhat similar to the dissociative agents ketamine and phencyclidine. It may produce distortions of the visual field - feelings of dissociation, distorted bodily perception, and excitement, as well as a loss of sense of time. Some users report stimulant-like euphoria, particularly in response to music. Dextromethorphan usually provides its recreational effects in a non-linear fashion, so that they are experienced in significantly varied stages. These 5 stages are commonly referred to as "plateaus".
