Would you consider Red Dawn or Classic Caramel from EV as hybrids ? If you haven't tried them, you'll taste the virginia and the burley at about 70%-80%, the remaining is flavoring or casing.
My post wasn't worded very clearly. By added flavors I meant adding additional flavoring when mixing a juice would create a hybrid. So a hybrid NET would includes the tobacco extract plus additional flavoring ingredients. If someone extracts a tobacco that has flavors added during the processing of the tobacco, such as a flavored cavendish or an ACID cigar, and makes a finished juice without adding any flavoring ingredients, it's not a hybrid.
