Not really accurate when it comes to Irish people;) I first moved to Ireland in 2006, then after years of balancing between different countries came back in 2012. Ireland is an IT hub of Europe and Irish people are very modern. However, when it comes to the private, "real", an offline life they are probably the best people to have around. Friendly, love to sing and love to party.
The thing about smoking - it is not trendy anymore. Nowadays being healthy is trendy. I am smoker anyway;)
Good luck and be more positive;)
