What is your opinion on legalization of Marijuana?

Recently this question startled me, as I didn’t think much about it. However after giving it some thought I wanted to share it with others.
Canada belongs to G7 developed countries as per UN World Economic Situation and Prospects 2018 report.  Canada has ranked twelve in the UN's annual Human Development Index (HDI 0.926), out of nearly 200 countries. The HDI measures health and life expectancy (82 years at birth), access to education (16.4 years of schooling) and standard of living (average earnings per capita 43,433).
Based on this statistical data I presume Canadian citizens are capable of making the right choices for themselves in every aspect of their life. I think legalizing Marijuana for recreational use in moderation has several positive aspects:
1. Cash flow redirected into Federal, Provincial, Municipal budgets to help fund growing needs of our society. Gambling, Tobacco, Liquor sales have been contributing to Canadian economy steadily for many years, but they reached their peak and can’t provide growth required for further generations. 

2. After government will enact quality control over marijuana production and sales, marijuana products would become safer for consumption.I was taught in school that demand creates supply, but not vice versa. In this situation people that were not using marijuana before its legalization won’t start using it just because it became legal.
 
3. Educational programs funded by marijuana sales will provide information about positive and negative effects, safe dosage, etc. Nobody should be left in the blind spot. I believe educated people are capable of making the right choices for themselves depending on circumstances. 
4. Marijuana industry will grow and provide working spaces for our citizens, reducing unemployment rates. 
​
Canada is a land of opportunity and this is just another opportunity to embrace with open mind. As Canada is a second country in the world (Uruguay first) to legalize marijuana, we are leading the world in this matter. Stay positive, Canada!
