What is the opposite of sobriety?

The opposite of sobriety is impairment. Sobriety refers to the state of being sober, which means not being under the influence of alcohol or drugs. Impairment signifies a decline in physical or mental function, often due to the influence of substances. When someone is impaired, their ability to think clearly, react appropriately, and make sound decisions is compromised, which is the direct opposite of the clarity and self-control associated with sobriety.

In the context of the other choices, temperance refers to moderation or self-restraint, particularly in the consumption of substances, which aligns more closely with sobriety. Abstinence means refraining from certain behaviors, often relating to substance use, but does not necessarily imply a lack of intoxicating influence at a given moment. Moderation involves controlling the amount of substance consumption, which still allows for a degree of sobriety. All of these concepts relate to sober behavior, but impairment directly contradicts the state of being sober.
