Thats true. But i think if you forbit it completly there will be a lot of more crime.
I am in favor of legalizing, regulating and of course heavily taxing the entire production chain. There are two main advantages of legalizing that drug.
1. It creates a source of tax revenues which is voluntary and the pot users tend to be libtards who deserve to be taxed anyway because they always want to raise more taxes.
2. It removes the criminals who control that drug trade. Let decent law abiding citizens benefit instead of letting mafia and gangs to rip all the profit from the trade leaving the rest of society with all the negative implications of pot using plus all the collateral damage they create with their criminal enterprises.
