I don’t know much about it. I remember seeing a few videos of not-so-well-known reviewers doing reviews of of dry herb vaporizers using tobacco because back then YT didn’t like the idea if people vaping drugs on YT. But now that drugs are normal and tobacco is all but illegal, I supposed things have changed.
At any rate, I had no interest in it myself but these devices they were using were all the cheaper stuff on the market at the time.
I don;t see why a device that was made for the funny tobacco wouldn’t work with actual tobacco, but what do I know.
As far as regulating the nicotine, it’s no different than smoking. You have no idea how much nicotine is in a cigarette and a google search is pointless as you’ll find all different answers.
