Not sure what fe cohiba is. Whether it’s a
juice, a flavoring, a flavor, or what. Sounds like a tobacco flavor. The traditional solution for that is menthol. You can get it several ways. The “OG” is in little spiky clear crystals you mix with high molarity ethanol to make a really powerful menthol flavoring. It’s supposed to be not good for you. I can support this in that I smoked menthols till I coughed up blue. There is a “flavor enhancer” flavoring sold by flavorwest. No idea what is in it which makes it iffy and I’ve never tested it. S’ cheap though.
