9 Most Addictive Substances Known to Man

Whether it’s the back alley, the club district or the boardroom, addictive substances are everywhere. At one point or another, you’re bound to come across at least one or two of the items on this list. So, pay attention, educate yourself, and consider yourself warned. Here are 9 of the most addictive substances known to man.

1. Alcohol

Alcohol is easily the world’s substance of choice. It’s widely available, it’s affordable and it’s legal. It’s also been around for centuries.

Made from fermented grain, juice and even honey, alcohol interferes with the communication pathways in the brain. The popular party beverage often lowers inhibitions and can relax your muscles in small doses. The danger, though, is with prolonged abuse.

You can develop a physical dependence on alcohol, causing withdrawal symptoms like mood swings and violent shaking. Add to that, going “cold turkey” is very dangerous for those in the advanced stages of alcohol addiction. In those extreme cases, medical assistance is highly recommended.

2. Heroin

Heroin is an opiate, extracted from the Opium plant, and was initially developed as a painkiller. Today though, it’s widely recognized as the most addictive substance in the world. It’s 2 to 4 times as strong as morphine and individual tolerance builds incredibly fast. Translation: the more you do, the more you need.

Heroin can be smoked, snorted and injected, and the withdrawal symptoms are terrifying. Depression, sweating, achy bones, cramps… and the list goes on. Recreational heroin use is on the rise as of late, making it even scarier.

3. Nicotine

No advertising. Warning labels. Restricted public use. A high tax rate. All of these restrictions have been introduced to curb cigarette smoking throughout the world and yet, smokers still find a way. It speaks volumes to the addictive qualities of nicotine.

The effects of long-term cigarette smoke are also impossible to deny. Lung cancer, emphysema, heart disease, strokes… it’s safe to say that if you’ve never puffed a cigarette before, don’t start now.
