What effects does phencyclidine (PCP) produce when smoked?

Answer: B — state of euphoria lasting 3 to 5 hours

Phencyclidine (PCP), when smoked, typically induces a powerful sense of euphoria that can last approximately 3 to 5 hours. This drug acts primarily as an NMDA receptor antagonist, which alters the levels of neurotransmitters in the brain and can lead to feelings of extreme happiness or an altered state of consciousness. Users may experience enhanced sensory perceptions alongside this euphoric high. The duration of this euphoric state is essential to understand, as it differentiates PCP from other substances that may induce similar feelings but for shorter periods. Knowing the expected effects and durations helps in both assessing the risks of use and addressing issues related to impaired judgment and motor skills associated with its use. Other durations or effects listed in the options do not align with the well-documented effects of PCP. Understanding the typical pharmacological impacts of substances like PCP is important for safe and informed discussions around substance use.
