The ADA is a law passed in 1990 aimed at preventing discrimination against a wide variety of characteristics, including race, religion, gender, and national origin. Alcoholism and drug addiction are both disabilities under the ADA, although they are treated differently.
If you are currently using illegal drugs you are not covered under the ADA. However, if you are currently receiving treatment or are successfully recovered, you are protected from discrimination based on past drug addiction. Any positive drug test is considered “illegal drug use” and the ADA protections no longer apply.
A person who currently uses alcohol may still be considered protected under the ADA, so long as it does not impact job performance or your qualifications for that job. If alcohol impacts your ability to hold a job and perform normal job functions, your employer is within their rights to discipline or fire you, as appropriate.
