Mia's use of illegal drugs limits her ability to walk properly. The elevator at her office was not working for many months, so Mia needed to climb two flights of stairs and had difficulty getting to her desk. She tried suing her company under the Americans with Disabilities Act, arguing that her company discriminates against individuals who cannot perform major life activities. Which statement would weaken Mia's argument?

a. Mia is not a senior employee.
b. The ADA prohibits discrimination only against workers who are over the age of 40.
c. The ADA does not cover conditions of substance abuse.
d. Mia is not pregnant.
e. The ADA applies only to the decisions or actions of the government.

The Americans with Disabilities Act (ADA) of 1990 was enacted to protect impaired individuals from being discriminated against or not provided with fair conditions due to their disabilities. The disabilities covered by the ADA are major not minor impairments. Besides, temporary disabilities caused by the abuse of drugs or alcohol are not part of the coverage that the ADA grants -just like in Mia's case.
