You have not lived a perfect day, even though you have earned your money, unless you have done something for someone who cannot repay you.

North Americans and Australians are among the countries that use marijuana the most, according to a paper published in The Lancet, the journal of the British Medical Association.
It is estimated that more than 8 percent of people ages 15-64 in the United States, Canada and Australia use marijuana at least once a year. Europe was next the annual usage data, followed by the Middle East and Asia. Marijuana use in Africa was still low compared to other geographic regions.
The study was conducted by the the National Drug and Alcohol Research Center of the University of New South Wales, in collaboration with the University of Queensland.
The study also traces a number of adverse effects to marijuana use including an increased risk of car accidents, impaired respiratory function and heart disease. It also highlighted the effects of regular use on adolescent psychosocial development and mental health.
The Lancet study included an estimated from the United Nations’ Office on Drugs and Crime that marijuana was used by 166 million people worldwide in 2006.
