We understand, however, the preference of the police force to use hair follicle testing over urine testing. Testing using hair samples is considered as more effective and accurate; it can detect drug use over a 90 day period and has a better track. This led to his rejection from joining the force, even if he was already    at an advanced stage in his application. There is a reason why there are various ways through which drug testing can be done â it is so that there can be another way of administering it should one way fail.

He was likewise unable to provide the alternative â about 200 strands of body hair. In the dale of a man (who will remain unnamed) who applied to the Police Service in Northern Ireland (PSNI), there was no way that he could submit to a hair follicle drug test. This caused a bit of a problem in his bid to enter the police force, as shared in a feature on. Itâ not because he does not want to â but because he cannot, being as it were that he was bald.

His baldness prevented him from providing hair samples of up to 3 cm in length.
