What is 'Robo Tripping?'

These drugs distort a person’s visual and auditory perceptions and produce feelings of detachment -- from the self and the environment. Although PCP and ketamine have mild-altering effects, these are not hallucinations. The proper term for PCP and ketamine, according to National Institute on Drug Abuse (NIDA), is "dissociative anesthetics."

Names for these drugs are: PCP, or phencyclidine ("angel," "angel dust," "uppergrass," "zombie"), and ketamine ("K," "Special K," "cat Valium") are dissociative drugs that were initially developed as general anesthetics for use during surgery.

What happens to cause the effects?

Dissociative drugs, PCP in particular, produce an almost instant trance-like feeling and users experience a rush of euphoria, a sense of pleasure and detachment from reality. PCP alters dopamine in the brain, resulting in the predictable euphoria and rush that users and abusers of dissociative drugs crave. The effects of PCP can last for hours, and some users report the feelings last for days.
