Note:
The above chart gives approximate detection periods for each drug substance. Ranges can be affected by factors such as amount and frequency of drug use, drug tolerance, metabolic rate, body mass, age, overall health, pH, etc.
Amount and Frequency of Use:
Small, single, isolated doses are generally detected at the lower end of the range with chronic and long-term use typically being detected at the higher end.
Drug Tolerance:
Individuals that establish a tolerance for the drug usually metabolize it faster.
Metabolic Rate:
Individuals with a slower metabolism are prone to longer drug detection periods.
Body Mass:
In general, human metabolism slows with increased body mass, resulting in longer drug detection periods. Also as THC and PCP are known to accumulate in fatty lipid tissue, individuals with a high percentage of body fat in relation to total body mass are subject to longer drug detection periods for those drugs.
Age:
As one’s metabolism usually slows with age a longer drug detection period could be a result. Overall Health: Typically one’s metabolism slows during periods of deteriorating health thus resulting in longer drug detection periods.
Urine pH:
Urine pH can impact drug detection periods. Typically, highly acidic urine results in shorter drug detection periods.
