I’m not sure this alone will work, but you’ve gotta start somewhere.
As someone who smoked through Uni and for a good few years after, the constantly increasing price was never really a factor in making me stop. I’m pretty sure that banning smoking in pubs and restaurants etc had a huge effect, as that really drives a change in behaviour.
Thus, upping the price on booze will start to raise awareness, cause at least a few questions before a purchase, but I kinda hope its a step in a plan change behaviour around getting smashed. It won’t work on its own. See also sugar-tax.
