Making Drinking Alcohol Safer

Today's news stories are about UK police shutting down premises associated with assaults and rapes. 18 year old student drinks vodka bottle in 15 minutes and falls to his death down a flight of stairs.
Don't alcohol bottle labels in many countries warn you to limit the amount you drink, like pills? If not, they should.
I've read several incidents of people dying on stag nights, usually the groom or best man. Now it's colleges. We should bring in laws like the Scandinavians. Drink must be served only with food. Anybody who spikes a drink, serves anybody else too much alcohol, or encourages them to drink dangerous amounts should be held responsible.
