Today many people around the world smoke marijuana for therapy or recreation, which is grown by nature, but in some countries nature is illegal, except for one legal substance: alcohol. In fact, Spanish language marijuana or marihuana can also be known as cannabis, hemp, weed, and weed. Marijuana is a dried, ground, green and brown mixture of the leaves, flowers, stem and seeds of the hemp plant, whose scientific name is Cannabis sativa (National Institute Drug Abuse, 2012). Marijuana has a long history of use as a medicinal herb and its use has been widespread throughout the world, from China to India and North Africa to Europe for thousands of years. They also have several different cultures in various ways. For example, it was recorded as a medicine to treat many types of health problems by the Chinese, and the first cloths and ropes were believed to have been woven from dried hemp, and around 6000 BC, marijuana seeds were used as food in China (Canadian Medicinal Marijuan, 2010). The Persian prophet Zoroaster also wrote a sacred text on the “Zend-Avesta”, in which he listed that marijuana was among the 10,000 medicinal plants in 550 BC (Canadian, medical Marijuana, 2010). Marijuana has adapted to people's lifestyle and social environment for thousands of years. In Canada, marijuana is now the biggest war on drugs and users that we can't get out of, but the country wants people to be safe. Globally, Canada is the country with the largest consumers (children and young people) of marijuana according to a UNICEF report, and the World Health Organization has established, based on a survey conducted on 15,000 Canadians, that Canadian children aged 11 to 15 tried marijuana for 12 months. ago, and it's the highest rate since......half the paper......that's more paper than a normal tree, so people consuming hemp products is another way to help the forest to grow and allow animals on land rather than extinct. Furthermore, the legalization of marijuana is able to create many jobs for many people for production because hemp can be used to produce oil, clothes, soaps, lip balms, butter, and ropes. Therefore, legalizing marijuana will make society safer and more valuable. Many people have a bad and dirty drug as an image of marijuana, and many children have been told to stay away from drugs, but some adults are involved. If Canada can be one of the countries that are legalizing marijuana, then it will have multiple beneficial impacts, such as medical purposes, personal uses, economy and society. So, legalizing marijuana is a step that can make people live in a better place.
