Since applicants are generally deemed to have a lesser expectation of privacy than current employees, employers enjoy greater freedom to test applicants, without the same concerns being invoked. However, to contain costs, many employers limit drug testing to those applicant whom they expect to offer a position to, as a condition of hire. While there is no requirement to notify an applicant in advance of a drug test, he or she is free to refuse to submit to it. Refusal to submit, of course, may be grounds to terminate the application process.
