Opiate drugs are those drugs that derive in some way from the opium poppy plant. Those that are synthetic are called opioids, but the two terms are often used interchangeably. Opiates are used for their narcotic, painkilling properties and are often prescribed in the forms of oxycodone, hydrocodone, codeine and morphine. Illegal opiates include heroin and opium. Opiate drugs are highly addictive and must be taken with great caution. All too often people in Alabama and across the United States who take opiates for legal or illegal purposes fall victim to addiction. Alabama drug rehab centers can help you if you have developed an opiate addiction.
