PCP and Other Drugs
PCP is sometimes mixed with other substances, making it even more dangerous. It’s been found in tablets, powder, and liquid forms disguised as other drugs.
Mixing PCP with Other Substances
- Alcohol: Increases risk of respiratory depression and unconsciousness.
- Opioids: Raises overdose danger and lowers blood pressure.
- Amphetamines: Increases heart rate and blood pressure, leading to panic or heart problems.
- Antidepressants like venlafaxine: Can cause dangerous drug interactions affecting mental health.
Lynk Diagnostics recommends professional testing if there’s any suspicion of polydrug use, since PCP mixtures can lead to toxic reactions and unpredictable behavior.
Route of Administration and Detection
How PCP Enters the Body
PCP can be taken in several ways, known as the route of administration:
- Smoked: Often mixed with mint or marijuana.
- Swallowed: As a tablet or capsule.
- Snorted: As a powder through the nose.
- Injected: As a liquid into the bloodstream.
Each method affects how fast PCP reaches the brain and how long it stays in the body. Smoked or injected PCP acts quickly, while oral doses last longer.
How Long PCP Stays in the Body
The detection time for PCP depends on several factors:
- Dose: Higher doses stay longer.
- Metabolism: Slow metabolism delays clearance.
- Body fat: PCP stores in fat cells and releases slowly.
- Frequency of use: Regular use increases detection time.
Approximate detection windows:
- Urine test: 3–7 days
- Blood test: Up to 3 days
- Saliva test: 1–2 days
- Hair test: Up to 90 days
