When people think of common addictions, their minds automatically go to illegal drugs. The reality is that there are many addictive substances in our everyday lives. It’s easy to become dependent on legal substances like coffee and alcohol. Meanwhile, there are also behavioral addictions that also affect our physical health.
Today we’ll look at some of society’s most common addictions and what they do to human bodies. We’re looking at everything from the most devastating opioids like fentanyl to video game addictions. All of these can wreak havoc on our quality of life.
Nicotine
Tobacco is one of the most devastating drugs on the planet that causes millions of pointless deaths every year. It contains nicotine and sends dopamine to the brain in 20 seconds. That’s why so many people crave the positive feeling of relief that they get from smoking cigarettes.
However, this highly addictive substance increases blood pressure and heart rate. It also causes a narrowing of the arteries. Another issue is that because people usually consume nicotine through smoking they suffer further negative effects. Smokers are up to 30 times more likely to live with lung cancer (via Cancer Research UK).
