Be it resolved that the government should adopt the legalization of marijuana.
Marijuana, also known as cannabis is a product of the plant Cannabis sativa. Humans have been consuming cannabis for centries. Although in the 20th century there was a rise in its use for recreational, religious or spiritual, and medicinal purposes. It is estimated that about four percent of the world's adult population use cannabis annually. The possession, use, or sale of cannabis products became illegal in most parts of the world in the early 20th century. Since then, some countries have intensified the enforcement of cannabis prohibition while others have reduced the priority of enforcement or lessened the penalties for possession of small quantities.
A psychoactive drug or substance is a chemical substance that acts primarily on the central nervous system where it alters brain function, resulting in temporary changes in perception, mood, consciousness and behaviour. The main psychoactive substance found in the cannabis plant is tetrahydrocannabinol or THC.
In 2006, a large-scale study found that people who smoke marijuana, even heavy, long-term marijuana users, do not appear to be at increased risk of developing lung cancer.

Why is marijuana illegal? It's because of the proposed health risks and the idea that it may impare your judgement. Well isn't that what cigarettes and alcohol do also?
