Yes, and legalise, tax, and regulate marijuana instead of criminalizing it

people become addicts and if you legalize one we must legalize them all and they will ruin our streets

This is all evident in countries and cities who have already decriminalised and/or legalised. Look at Amsterdam, Holland for the best example. Germany now following suit, and the biggest one of all, an ally of ours, the United States of America. More than half of the states in America, and still rising, have legalised the recreational use of marijuana and have since only reaped the benefits. It's not just smoking and a high in which marijuana provides, it can provide hemp for medicinal use, construction, food and beverage, clothing and can provide thousands of jobs in the process
