where do they put the menthol in cigarettes
A recent innovation has been to include a small capsule in or near the filter which can be crushed to release additional menthol or other flavoring solutions. During the smoking of a cigarette the menthol delivery depletes noticeably, but this technology allows the smoker to increase the menthol delivery at a chosen point to sustain or enhance the menthol' feel'. The capsules can contain any flavorings but are primarily menthol.
