This act is passed in the exercise of the police power of the state. It is not designed to abridge the personal privilege of a responsible adult to consume alcoholic liquor as a beverage, except in cases of the abuse of that privilege to the detriment of others. The public interest requires that traffic in alcoholic liquor be regulated and controlled by the state, through the medium of a state liquor division vested with exclusive authority to import and sell such liquor, with certain exceptions, which are subject to its regulation.
