Is it common to smoke several different brands of cigarettes?

I know someone who does and i wanted to know what was up with that?
Answers:
All nicotin,tobacco. its ordinary
Yes and no. I mean, it doesn' really business but usually people get into the habit of asking for one and the same thing. I only change if my brand or type isn't available.
its normal
The only time that it is not normal is when " they smoke several different brands AT THE SAME TIME"
im duly sure inhaling smoke of any kind is not normal
