Which brands/blends have Cuban tobacco?

[a2vr6]

Just curious what decent brand/blends that have Cuban Tobacco mixed in? Just started sampling alot of the stuff out there but not sure of any Cuban blends. One other question, are any chemicals added to Pipe tobacco (of course other than what naturally is in there)? I know there is sugar and natural fruit flavors that go into many of the aromatics but are there certain blends that are blasted with crap to get there flavor?

Currently, I only know of Compton's up in Canada. They use filler from the RyJ factory in one of their blends.
