Thanks for the link, but even here the author goes no further than to say "Its wrapper appeared to be infused with a chili-like substance that, upon placing in my mouth, created a warm sensation across my lips and tongue"
"Appeared to be", based on the spiciness on contact with lips and tongue. He later says 'interesting idea, infused wrapper', but gives no reason in article for claiming this. Certainly no indication that this alleged info came from manufacturer or distributor.
See above, another poster "read somewhere" tip dipped, a la Baccarat.
I've had some hot and peppery to the tongue and lip cigars, none of which were claimed to be infused.
Infused? Tip dipped? Peppery tobacco? Seems these are still open questions.
