Tobacco, which entered Southern hoodoo through contact with Native Americans, especially the Cherokee tribe, has a place in hoodoo, especially in Court Case work and in work to contact those who are distant or absent, or when working as a medium with an Indian Spirit Guide. However, there is no specification that a "cigar" must be used in conjure -- just "tobacco" -- and very often this takes the form of a cigarette or powdered snuff (e.g. Garrett's snuff, as shown), not a cigar.
To require the use of a cigar *is* common in Cuban religions of the various African Diasporic branches, e.g. Lukumi, Santeria, Voodoo, and Palo) and their magical derivations -- but those are not hoodoo.
If you have learned the trick you are practicing (which you do not bother to describe here) from a hoodoo practitioner, and you are told that a cigar is required, it is almost guaranteed that this teacher is also an initiate in Palo, Santeria, Voodoo, or the like. So perhaps you should ask your teacher, or a worker who comes from one of those traditions, how they deal with cigars. Because we rarely require a cigar in our work.
If the use of a cigar in your spell turns out to be part of a hoodoo contact spell, you may substitute any other form of tobacco: snuff, cigarette tobacco, Tobacco Oil, Tobacco Incense, Black Candle Tobacco, etc.
If the use of a cigar in your spell turns out to be part of a religio-magical offering to an African diasporic deity (orisha, lwa, mpungo) in an African diasporic religion, but that religion is not one in which you are initiated (and this seems to be the case, else you would not have asked us about it), then you might alternatively consider turning to a spell from a different religious tradition, in which you can live tobacco-free because cigars are not considered to be standard offerings. In short, why not try straight old-style Southern American hoodoo?
Next, i note that you say your house smells "like Glade plug-ins." What a shame! You are totally losing and wasting the opportunity to scent your home with natural, magical, herb-based aromas. Why use synthetics in a petrochemical base when you can spritz Peace Water around the premises, or wash things down with Chinese Wash?
Give the natural aromas a chance.
