Not really a haven for non-smokers

Be warned that there is virtually close to none non-smoking etiquette practised in the country.  You may see signs saying that a certain area in for non-smokers, but don't bet that anyone cares.  You might even see some smoking directly under these signs!

So, if you have asthma or can't tolerate the better to avoid public places where there are lots of smokers, or bring along some masks to help you breathe through the smoke.  Better yet, just stay at your hotel if you have nothing to do.
