How Addictive is Heroin?
One of the most addictive substances known to man, heroin reportedly hooks 23 percent of first-time users immediately.
Heroin is the most common opioid and it’s intensely addictive because the brain contains opioid receptors, specifically responsive to the chemicals in these types of drugs.
Heroin users snort, smoke or inject liquid pleasure, causing an intense rush some have likened to the warm, happy, relaxed feeling of long-lasting sexual satisfaction. In time, heroin users lose the ability to feel any good sensations without using.
Chronic use of heroin leads to physical dependence, a state in which the body has adapted to the presence of the drug. If a dependent user reduces or stops use of the drug abruptly, he or she may experience severe symptoms of withdrawal.
