Answer: ADA does not consider drug test to be a medical test.
Step-by-step explanation:
Under the ADA, an employer is allowed to demand a candidate or current employee to undergo a drug test to determine whether or not they use illegal drugs. The ADA won´t obstruct, nor require drug tests. However, although an employer is not allowed to demand a medical examination, drug tests are not regarded as such, so they can be required by the employer.
