When we consider the potential of Marijuana as tax revenue cash cow, I find it hard to believe the revenuers haven't figured out how to rationalize legalizing. Whenever a vote on the floor has been a tough sell in sessions past, they draw out that good old "The money will go to education" lie.
Gambling used to be a 'sin,' until the states decided they wanted in on it. Now it's OK.
It's just a matter of time for pot.
