How do menthol cigarettes work?

They put menthol in the filter. Rip the tobaco of a menthol cigarete and draw clean air through a clean menthol cigarete filter and it wil be mentholated air.

No they don't. The tabocco itself is menthol. I smoke menthol tobacco and I use normal filters, not menthol filters, which I don't even know if you can buy.

Rub Vick's Vapor Rub on the filter, and it will kinda taste like a menthol.

your both right it depends on the brand. alot of camels use menthol in the filter and they have to put alot to oer compensate for the menthol not being in the tobacco like crushes. camel silver menthols have both they have menthol in the tobacco and a ball you can crush in the filter to make it more menthol. as for making a cig taste like menthol ive heard people say tooth paste but it does not work it cloggs the filter. havent tryed anything else.
