What Is PCP (Phencyclidine)?

PCP, the common name for Phencyclidine, is a hallucinogenic substance that affects the brain in various ways. PCP was first used in the 1950s as an anesthetic and later became popularized in the 1960s and 70s as a recreational drug. Popular for its ability to cause the user to detach and disassociate from their surroundings, it produces a strong feeling of euphoria. The Schedule II controlled substance goes by several street names such as:

  • Angel dust
  • Hog
  • Amoeba
  • STP
  • Super grass
  • Zoom
  • Belladonna
  • Peace pills
  • Boat
  • Animal trank
  • Sherm sticks
  • Embalming fluid

The drug is known for uncomfortable withdrawal effects, producing delusions, irritability, and anxiety when “coming down.” PCP can be in liquid form, yellow or clear in color, or in a power or tablet form, easily dissolving in water. PCP  is also often mixed with other drugs, such as ecstasymethamphetamineLSD and mescaline, typically without the user’s knowledge. Reports of drug users have included combining PCP with tobacco as they “dip marijuana or tobacco” in embalming fluid speculated to be PCP.

PCP can be smoked, snorted, taken orally, sprinkled on other drugs or injected.

PCP Addiction

Phencyclidine is addictive as it impacts the brain’s chemical composition. Upon ingesting PCP, people experience joy, and the perception of clear thinking. Typically, people can feel results of PCP rather quickly depending on how they have taken the substance. For instance, someone injecting PCP can feel the effects in 2 to 5 minutes; smoking PCP can be felt in the same amount of time, lasting to half an hour. Lastly, if someone swallows it, they can feel it in 30 minutes, with intense side effects occurring at 2 to 5 hours.

Because of the altered states of existence people feel under the influence of PCP, many can become dependent on the drug, especially individuals seeking sensory distortions or pseudo-spiritual experiences. People taking PCP also experience mood changes and poor coordination. Side effects of PCP vary based on small and large doses. Common symptoms of PCP addiction are:

  • Delusions
  • Confusion
  • Hallucinations
  • Euphoria
  • Exaggerated strength
  • Increased heart rate
  • Numbness
  • Increased blood pressure
  • Feelings of detachment
  • Rapid respiration rate
  • Memory loss
  • Physical and psychological distress
  • Anxiety
  • Paranoia
  • Seizures
  • Chills
  • Muscle cramps
  • Vomiting
  • Death
  • Rhabdomyolysis
  • Dehydration
  • Loss of coordination
  • Disorientation
  • Extreme fear or panic
  • Invulnerability
  • Aggression

Every person will have an unpredictable, varying experience on PCP due to the different symptoms that may occur on each trip. Therefore, someone may use PCP and become aggressive, and someone else may become overly empathetic or anxious. It is very hard to distinguish with PCP which symptoms will occur because it often depends on the mental state the user is in before they take them.

Other signs of PCP addiction are the inability to control one’s intake or increasing one’s PCP intake.  Such challenges can create long-term effects lasting up to a year like suicidal thoughts, mania, flashbacks, and social isolation.

PCP is especially dangerous to mix with alcohol or other depressants because it can lead to respiratory distress or arrest, resulting in death.
