What's the difference between Series A and Series B?

So, I’ve got a question about cigarette series. Specifically, I’m sitting here holding a black Avangarde—that's a Series B with 0.9 nicotine and 0.9 tar/$5.75—and a Benson Series A at 0.8 nicotine and 1.0 tar/$4.75. The only thing I've noticed is that the Benson doesn't leave much of a taste in my mouth, but my fingers smell absolutely terrible after smoking them. With the Avangarde, the finger smell isn't bad, but it leaves this weird, annoying aftertaste in my mouth.

Does anyone actually know the difference between a Series A and a Series B?

ps. They kicked this thread off the Health and Food subforums, so I had to move it here.🤷

I’ve got this crazy gut feeling that it all boils down to how much nicotine and tar you're actually pumping into your system😂😂

I mean, I'm just guessing here, but it probably comes down to the quality of the tobacco itself.

Could the difference perhaps lie in the packaging, like whether it's soft or hard? 🤷

Oh, this is just great. I was actually looking at my pack of Marlboro just now and noticed it says UC on it... which, honestly, makes me wonder—which specific class or series is that even supposed to be?

Series A gets packed from midnight until noon, while Series B runs from 12:01 PM through midnight. ☕
