Top 3 Most Addictive Substances in the World
Heroin
Heroin is an extremely addictive opioid drug derived from morphine. The drug is so addictive, in fact, that just one use can cause someone to develop a serious, long-term addiction.
Often used as a narcotic, heroin produces feelings of euphoria during use. In a short amount of time, the body can develop a tolerance to heroin, which prompts users to increase their dosage in an attempt to continue experiencing its euphoric effects.
In addition to providing an addictive feeling of intense pleasure, heroin also creates painful withdrawal symptoms that prevent many from recovering. Some of the withdrawal symptoms associated with heroin use include severe bone and muscle pain, cold flashes, vomiting, diarrhea, and sporadic leg movements.
Cocaine
Another one of the most addictive substances in the world is cocaine. Cocaine is a stimulant drug derived from the coca plant and manufactured into either a white powder or rock form. When smoked, injected, or snorted, cocaine creates an intense high by flooding the brain with the neurotransmitter known as dopamine.
The mental effects of taking cocaine include euphoria, alertness, loss of contact with reality, and excitement. Such effects, however, are typically short-lived, which is why many users take doses of the drug back to back to maintain the high. When cocaine inevitably wears off, users experience a crash that may include depression, mental and physical fatigue, and severe cravings, making the drug extremely hard to stop using without professional help.
Nicotine
Nicotine is one of the primary active chemicals in tobacco smoke. Once absorbed through the lungs, into the mucosal lining of the mouth and nose, or into the skin, nicotine creates pleasant sensations, boosts one’s mood, and—similar to cocaine—increases dopamine in the brain. Such effects typically take effect in a matter of seconds after smoking nicotine.
After just a few days of smoking nicotine, symptoms of addiction can begin to emerge. As such, over two-thirds of Americans who try smoking become addicted during their lifetime. Currently, nicotine is the most common addiction in America. Despite serious health concerns, such as insomnia and increased risk of cancer and heart attacks, nicotine is extremely difficult to stop using. The prevalence and legality of nicotine may contribute to its high relapse rates.
