When using detection periods you also need to keep in mind that there are limitations to the accuracy of time specified. As such, detection periods should be used as a guide. Some limitations that may alter a person’s detection period include:
- Everybody is different – no two metabolic rates, age, and general health are the same thus their bodies will show different consumption concentrations.
- Different consumption methods – by consuming a drug orally compared to injection can lead to different concentration levels within the body.
- Different consumption quantities – the frequency and the quantity of a drug can also affect how long the drug will expel from your system.
- Cut-off levels vary – Cut-off levels vary within Countries and Organisations. If your cut-off levels are lower then it will take longer to dispel the drug from your body and vice versa.
