I [26M] have a friend that without a doubt is addicted to cigarettes, I'm pretty sure he tried to quit before or lower the consumption but last time I knew how much he smoked was about a whole box daily

Now, I travel from time to time and since I went to Japan I bought him Japanese cigarettes as a gift
Now since I'm going to see him again in a few months he asked (or I suggested I don't remember) to bring him American brands that don't sell in Mexico, or at least in my city that I've seen (American Spirit, Newport)

The dilemma came when some of my friends from the same group started pointing me out as a bad friend or a devil's advocate

The way I see is: I know my friend will smoke and will continue to smoke, independently of if I bring him foreign brands or not, at the end the only thing I'm doing is saving him some weekly money not adding quantity of cigarettes/month per se

For the sake of the question, please put aside personal beliefs on sommeliers. Some argue they are real and some argue they are a scam. I can see both side of that. But in this scenario, we are all believing that sommeliers' work is completely proven and supported.

What if there as a high end dining restaurant and they hired the best known sommelier in the world? However, the sommelier was an alcoholic. Not a raging or miserable one, but someone who definitely drinks like a fish and has a serious problem with putting the bottle down.

But they are dynamite at their job and helped make the restaurant more world renowned. They outclass every sommelier in the world, they show up to work on time without being a drunk mess, and they are loved by everyone in the restaurant, including customers. But the management knows this sommelier has a serious drinking problem outside of work. They drink themselves to sleep every night but show up sober enough to legally and functionally work.
