This article should be completely rewritten
The article has a lot of outdated (e.g. Vegas Smoke does not sell tobacco for at least a year, Nichols & Brown is also out of business if I am not mistaken), misleading (e.g. absense of additives (?) in non-aromatic blends, British laws and adulterants in tobaccos) and wrong (e.g. Percy Martin is the only grower of the "authentic" Perique).
The number of readily available tobacco related resources is enormous. This is symptomatic that only resources of not clear credibility are mentioned.
