If you're a smoker planning a trip to Austria and Bavaria, good news. You'll have a lot of company. I was quite surprised at how prevalent smoking was, perhaps because I'm used to living in LA where it's practically a hanging offense to light up.
When you're out walking around, it's quite likely several someones in front of you will be sharing their smoke with you. And when you exit an airport or train station, you'll have the pass through a scrum of people madly puffing away. So if you have respiratory issues or allergies, be prepared and take precautions.
It's also quite easy to buy smokes from vending machines, as well as vaping cartridges. Age controls loosely enforced if at all.
I suppose the good news is, most machines that sell ciggies also sell little airplane sized bottles of booze to get the party started.
