Cross-tolerance allows an individual to show increased tolerance to which kind of drugs?

Cross-tolerance refers to a phenomenon where an individual develops a tolerance to one drug, which subsequently leads to an increased tolerance to another drug that is chemically similar or belongs to the same class of drugs. This is because both drugs often share similar mechanisms of action in the body.

For instance, if someone becomes tolerant to opioid pain medications, they may also exhibit tolerance to other opioids, such as morphine and codeine, because these drugs interact with the same opioid receptors in the brain. This principle is significant in both understanding substance use disorders and in effectively managing pain management therapies.

While the other options mention different drug classes, all medications, or non-drug interventions, these do not accurately reflect the specific nature of cross-tolerance, which is inherently linked to drugs within the same class.
