Detection Timetable Depends on Many Variables

Estimating how long TCP (Tenocyclidine) is detectable in the body depends on many variables, including which kind drug test is being used. TCP - also known as N-[1-(2-thienyl)cyclohexyl] piperidine - can be detected for a shorter time with some tests, but can be "visible" for up to three months in other tests.

The timetable for detecting TCP in the system is also dependent upon each individual's metabolism, body mass, age, hydration level, physical activity, health conditions and other factors, making it almost impossible to determine an exact time TCP will show up on a drug test.

The following is an estimated range of times, or detection windows, during which TCP can be detected by various testing methods:

How Long Does TCP Stay in the Urine?

TCP can be detected in the urine for 2-5 days.

How Long Can TCP Be Detected in Blood?

A blood test can detect TCP for up to 24 hours.

How Long Can a Saliva Test Detect TCP?

A saliva test can detect TCP for up to 1-5 days

How Long Can a Hair Test Detect TCP?

TCP, like like many other drugs, can be detected with a hair follicle drug test for up to 90 days.

Preventing an Overdose of TCP

TCP is an analog of phencyclidine (PCP) in which the phenyl substituent is replaced with a thiophene group. It is intended for forensic and research applications only.

However, when it is abused, TCP produces effects similar to the dissociative drug PCP except perhaps even more intense. The drug was placed on the list of Schedule 1 controlled substances when it was being abused in the 1970s and 1980s, but it is rarely used today.

A TCP overdose can produce symptoms similar to a PCP overdose, which include:

If if you think someone has taken an overdose of TCP, call 9-1-1 immediately or the poison control center at 1-800-222-1222.
