Drug abuse in the workplace puts employers at a risk of increased accidents, increased absenteeism, decreased productivity, and higher insurance costs. Hair testing, like all drug testing methodologies, helps to mitigate these risks by screening out applicants and employees who use drugs.
Hair testing for drugs of abuse is the only drug testing method available that provides up to a 90-day drug use history. When compared with urine testing, hair testing tends to provide a greater number of positives due to its longer detection window. Hair testing requires a small sample of hair that is collected under direct supervision without any invasion of privacy. It is an excellent option for pre-employment and random drug testing programs.
