Cannabis, also known as marijuana, is illegal in many countries due to its psychoactive effects. The plant contains a chemical called tetrahydrocannabinol (THC) which can alter the mind and cause a “high” sensation.

The criminalization of cannabis can be traced back to the early 20th century when many countries began to impose strict drug laws. The United States was one of the first countries to outlaw cannabis in 1937, largely due to political and racial motivations.

At the time, many people believed that cannabis was a dangerous drug that could lead to addiction and insanity. This belief was fueled by propaganda campaigns that portrayed cannabis users as violent and unpredictable.

In recent years, attitudes towards cannabis have shifted as more research has been conducted on its medicinal properties. However, it remains illegal in many parts of the world and is still classified as a Schedule I drug in the United States, meaning it is considered to have a high potential for abuse and no accepted medical use.
