Legalize Weed

Why should we be penalized for a plant that doesn't harm anyone? The only harm it does is to not have it legalized. Smoking weed should be legalized world wide for many reasons, the most being is to boost the world's economy. I'm sure many of us smoke weed for fun but it actually helps to cure brain tumor and balances your nervous system. Marijuana is legalized in the state of California and in it's first year of legalization the state earned a revenue of 30 billion dollars, imagine if all states were to be legalized. Some countries have legalized their weed for medical purposes which is a good thing because you have doctors these days that smoke medical marijuana for many different reasons and the most is to stay clam. Legalize weed and see what a change it will bring to the world.
