Certain temporary, non-chronic impairments of short duration with little or no residual effects usually are not disabilities. Likewise, environmental conditions and alternative lifestyles are not protected. A person currently engaging in the illegal use of drugs is not considered an individual with a disability. This refers both to the illegal use of unlawful drugs such as cocaine, as well as illegal use of prescription drugs.

Examples of conditions that are NOT impairments: The common cold or the flu, a sprained joint, minor and non-chronic gastrointestinal disorders, a broken bone that is expected to heal completely, compulsive gambling, pregnancy, old age, lack of education, poor judgment, or bisexuality or homosexuality.
