A list of the most addictive drugs. These are the 20 most addictive substances on Earth. All of them should only be taken under a doctor's supervision, if at all. The level of addictiveness is based on two separate studies. Multiple other studies have also been considered. Some of these drugs have medicinal properties. But even if taken as medication, one should still be careful. Just because it's medicine, that doesn't mean it's not potentially dangerous for your health.
A lot of these drugs should be recognizable. If you've seen the epic AMC drama Breaking Bad, you should be knowledgeable about the dangers of crystal meth. If you're a fan of musicians like Kurt Cobain and Amy Winehouse, then you know about the highly addictive nature of heroin. Let's not even get started on crack and oxycodone, two of the most dangerous drugs in the world.
Taking the drugs on this list probably isn't the best decision. The facts speak for itself.
