I don't think any tobacco blend has made me feel ill. Too much nicotine is unpleasant and makes me want to sleep it off, but it's not a blend-specific thing.
Yup, that'd definitely do it, all right.freshly opened tin of Nightcap.
If you mean, pre-carbonated, that shouldn't be. It's non toxic and only helps with the absorption and break in.Perhaps in my case the bowl coating added to my feeling of ill.
