Once you get away from Dublin and into Ireland proper you'll quickly discover some great pubs, many of which have decent smoking areas outside. Some heated and many partially enclosed to beat the wind and rain. Great place for pint and pipe while talking with the locals, away from the noisy craic inside. One place in Dingle has a great outdoor barbecue and talking cooking, pipe and pint in hand, is a great afternoon. Ask anywhere there, should you get to Dingle, they'll point you in the right direction. Great trad also. Add Roundstone, Co. Galway, to your itinerary if you can. A grand little hotel, Roundstone House, a couple of good pubs and two of the finest beaches, in my opinion, on the island. Dine on what my wife claimed was the finest Shephard's Pie in the world at the hotel.
Why a "throw away" lighter? If you're going into the Peterson store grab a couple of their lighters if the exchange rate is right. I usually bring back a couple for gifts.
