Which drug is commonly known as angel dust or angel hair?

Phencyclidine, commonly known as PCP, is the drug referred to as angel dust or angel hair. Originally developed in the 1950s as an anesthetic, PCP is known for its hallucinogenic and dissociative properties. Users may experience altered perceptions of sight and sound and may feel a sense of detachment or disconnection from their body and surroundings. The nickname "angel dust" comes from the substance's association with euphoric hallucinations and its perceived ability to elevate a user's state of mind.

While the other options represent different classes of drugs, none are associated with the specific effects attributed to PCP. Cocaine is a powerful stimulant, amphetamine is a central nervous system stimulant often used for ADHD and narcolepsy, and benzodiazepines are sedatives that are mainly prescribed for anxiety or sleep disorders. Each of these drugs impacts the body and mind differently, making them distinct from PCP both in their effects and common usage.
