Both the time it will take for a drug to be effective, and the time it will take for it to leave the body completely, depend on a drug's half-life. The half-life is the amount of time necessary for the concentration of the drug in the bloodstream of the body to be reduced by one-half. The time it will take for a drug to reach a steady state, or full effectiveness, in the system is based on that half-life.

Adverbs can also modify adjectives and other adverbs. Although many adverbs end ly, lots do not (e.g., fast, never, well, very, most, least, more, less, now, far, and there). Adverbs Modifying Verbs An adverb that modifies a verb usually tells you when, where, how, in what manner, or to what extent the action is performed. (NB: The ones that end ly are usually the ones that tell us how the action is performed, e.g., quickly, slowly, carefully, quietly.) Here are some examples of adverbs modifying verbs: 1  How: He ran quickly. 2  When: He ran yesterday. 3  Where: He ran here. 4  In what manner: He ran barefoot. 5  To what extent: He ran fastest.
