Leaves of the coca plant (Erythroxylum novogranatense var. Novogranatense), from which cocaine, a naturally occurring local<unk> , is derived. An<unk>  (American English) or<unk>  (British English; see spelling differences) is a drug used to induce<unk> esia ⁠— ⁠in other words, to result in a temporary loss of sensation or awareness. They may be divided into two broad classes: general<unk> s, which result in a reversible loss of consciousness, and local<unk> s, which cause a reversible loss of sensation for a limited region of the body without necessarily affecting consciousness. A wide variety of drugs are used in modern<unk>  practice. Many are rarely used outside<unk> esiology, but others are used commonly in various fields of healthcare. Combinations of<unk> s are sometimes used for their synergistic and additive therapeutic effects. Adverse effects, however, may also be increased.<unk> s are distinct from analgesics, which block only sensation of painful stimuli.
