You will have no problem in buying cigarettes at kiosks and Mini-markets. Unless it happens they are checked at the specific time, they will not ask you for ID.
If you mean to 200 box then no you wont, a 20 deck from newsagents might be easier and if you have any in suitcase they will see them at passport control and keep them, Good Luck
The minimum age to buy cigarettes is 18. You may well be asked to show ID and that means your passport.
You will survive not being able to smoke for two weeks. It will do you the world of good.
