There are a handful of drugs that do not fall under the category of prohibition, including alcohol and tobacco. The companies behind these substances have a long reputation of lobbying for their use on a recreational level, despite the known drawbacks of prolonged use among adults. According to the World Health Organization, nearly six million people die from tobacco use and 2.5 million from abuse of alcohol throughout the world each year. A large percentage of serious diseases, including heart disease and cancer, are also linked to tobacco and alcohol use, but both remain legal for adults to use recreationally. Marijuana use, on the other hand, has not been shown to lead to these types of statistics, and therefore, support continues to rise.
