I'm truly curious: which problems related to marijuana use (intoxicated drivers, access by children, etc.) do people think might worsen in a state where marijuana is legalized? It seems obvious to me that marijuana legalization would alleviate the two aforementioned issues by raising awareness of marijuana-related DUIs and eliminating distribution networks that sell to children, but I probably haven't considered other problems associated with widespread marijuana use.
