I'm not going to pull up statistics based on arbitrary consumption thresholds, but I would reason there are way more consumers of alcohol around me than smokers. Yet the number of times I've had to bear nuisance from smokers vs from drunkards is higher. Generally speaking, (here) smoking is forbidden in most indoor-ish spaces - which is the only reason smoking is anywhere close to the same level of nuisance as drunk people. Note that the same people that would enforce "no smoking" can also do something about the "practically unbearable" drunk person. And in outdoor-ish spaces, you can often avoid being affected - except in e.g. restaurants, where someone chain-smoking on the neighbor table can ruin the evening.
