Which drug is noted for usually maintaining body temperature within the normal range?

Cannabis is known for typically maintaining body temperature within the normal range due to its effects on the body's thermoregulation system. Unlike other drugs that can drastically alter physiological parameters, cannabis generally has a more stabilized impact on body functions, including temperature regulation.

CNS stimulants often lead to increased metabolism, which can raise body temperature, while CNS depressants may cause a decrease in metabolism and potential hypothermia. Phencyclidine (PCP) is known to cause significant alterations in body temperature, often leading to hyperthermia or hypothermia depending on dosage and individual reactions. Therefore, cannabis stands out as the option associated with maintaining body temperature more consistently, reflecting its relatively mild impact compared to the more extreme effects associated with the other substances listed.
