Yes you can, and George talked about it more often when the VC was new. Here are a couple of things that might help you if you decide to do it:
1. Pipe tobacco is apparently much better for this than cigarette tobacco.
2. A lot of people seem to prefer full convection heating (stuff like the Nomad, Milaana, etc.), so if you don’t like it with a VapCap don’t think you don’t have other options.
If you already smoke and you want fuck combination then I think it’s a much better option, but if you don’t already use tobacco/nicotine I hope you never start. I’ve seen too many people struggle for many years to quit and suffer a lot of health problems from it.
Some of that may be less bad if you don’t smoke it, but it’s still very addictive stuff with the potential to cause cancer and other problems, possibly even when vaporized. I’m pretty sure chewing tobacco can cause cancer for example, and there’s no combustion there.
If you want to see more, here’s a thread about it. You might also get better answers asking questions there:
