where does the menthol in cigarettes come from
Menthol cigarette Menthol cigarettes are constructed similarly to non-mentholated cigarettes, with menthol added at any of several stages during the manufacturing process. Menthol may be derived from distilled corn mint oil, or produced synthetically.[4] While trace amounts of menthol may be added to non-mentholated cigarettes for flavor or other reasons, a menthol cigarette typically has at least 0.3% menthol content by weight. Lower-tar menthol cigarettes may have menthol levels up to 2%, in order to keep menthol delivery constant despite the filtration and ventilation designs used to reduce tar.[4]
Parliament (cigarette) Parliaments are one of few brands of cigarettes on the mainstream market to feature a recessed paper filter. Cigarette filters became common in most cigarettes in the 1950s. In the 1940s and 1950s, the brand was marketed for its unique filters, with advertisements reading, "Only the flavor touches your lips", and "Tobacco tastes best when the filter's recessed".[3] The brand also claimed that the recessed filter prevented tar from making contact with the smoker's mouth, unlike standard filters.[4][5][6] However, this recessed would also explain the popularity of the cigarette in another way: the sleeve would be suitable for snorting cocaine.[7]
