Often these heroin users are under the misconception that if they do not inject the drug they will not become addicted. Those who have entered rehab to recover from heroin addiction include every method of heroin user. Annual admissions to substance abuse treatment for primary heroin abuse increased from 228,000 in 1995 to 254,000 in 2005; however, the proportion of primary heroin admissions remained steady at about 14 to 15 percent of all admissions. Between 1995 and 2005, inhalation and injection accounted for at least 94 percent of annual primary heroin admissions.

When posed the question, “Who’s using heroin?” the answer may not be what one would expect. An epidemic of heroin use over the past five years crosses generational, socioeconomic and geographic boundaries to plague all areas of American culture. Heroin, once a drug primarily associated with aging inner-city addicts, has become popular among suburban and rural populations, and is used by adults and adolescents.

Use of heroin in pregnancy also may increase the risk of a variety of birth defects. What is not entirely clear is whether these effects are directly due to the drug itself or related to the poor health behaviors that women who take heroin often have. It may also be caused by the substances that the heroin often is mixed with when it is made.

Living life without the need for drugs or alcohol is why people enroll in a drug rehab center. People who are addicted to drugs or alcohol often require help to stop using. An addict may try many times to quit on their own to no avail. This is because addiction is a very difficult problem to recover from without help. It takes time and a lot of effort to learn how to live drug-free and change one's approach and outlook about life in general.
