Drugs

Illegal drug trade have been going on for a long time now. People have been using these drugs for many reasons like relieving themselves of stress, pain and sadness. Some are using them because they wanted to be "cool" and fit in with the popular kids. Whatever the reason it is, they are literally just killing themselves in the long term. Drugs are addictive and deadly, as most people reading this should know. The addictiveness is the most dangerous part of it as without the addictiveness. It forces the victim to keep on taking it and sooner or later they might be dead if they don't leave the cycle.

Look at how much money was made from illegal drug trading rather than human trafficking, firearms and diamonds. Imagine how much people used their money to buy drugs.
