The drug comes from the opium poppy, papaver somniferum (which means sleep-inducing milk). It is usually sold as a white or brown powder that can be ingested, snorted, smoked, or injected into the bloodstream with a hypodermic needle. Heroin is a powerful respiratory depressant that is sought after for its ability to produce a euphoric “high”. This high produced by heroin is the lure of what draws people to the substance. Individuals who abuse heroin can become addicted very quickly people will quickly develop a tolerance the drug. Once the tolerance to the effects of the drug occurs in the body, a heroin abuser will require increasingly larger doses of the drug to produce the same high as before. At this point the heroin abuser will develop a physical dependency to the substance and becomes a heroin addict, needing the drug to just properly function and get through everyday life activities. When the drug addicted individual is unable to obtain heroin, they will experience heroin withdrawals and require a detox for heroin. Heroin abuse can spiral out of control rapidly into a full-blown drug addiction. Some users of the drug started with a prescription pain killer, such as Oxycontin, and when their habit to the pills became too expensive, they sought a cheaper, more potent high. They often found that in heroin. But like Oxycontin, the potential for addiction is so great with heroin. Heroin addiction has ruined lives, derailed many careers, and shattered entire families.
