Serious question – did you actually inhale?
There’s also of course the very real possibility that you’re just not sensitive to nicotine or need a much higher amount to “feel” anything than a typical person. I’m definitely that way with many drugs (recreational and otherwise). It’s part of the reason that I don’t do drugs – it’s way too hard for me to gauge how much I actually need so I end up overdoing it and suffering because of it.
I’m not trying to be the fun police and I agree that activities like smoking cigars, drinking beer, and coffee can be fun. I just don’t see the point in nicotine free cigarettes. So, to @anon75430791’s points about smoking cigars and not inhaling, what’s to stop you from just smoking a regular nicotine cigarette and not inhaling if you’re doing it truly for the “fun” aspect of it? I certainly did this more than once when trying to look cool as a youngling.
