TO: Dr. Hi. Wakeham FROM: Frank E. Resnik DATE: January 13, 1964 SUBJECT: Carlton's High Per Cent Nicotine in TPM The TPM from the Carlton cigarette contains 6.6% nicotine. The TPM from all other cigarettes (see page 11 of C.I. Report Number 58) contains from 3 to 5% nicotine. It is concluded that the Carlton's higher per cent nicotine in TPM is the result of the perforated cigarette paper just prior to the filter. It is postulated that the air coming through the holes during a puff flushes the nicotine trapped on the filter into the smoke stream. This conclusion was drawn from an~experiment where the Carlton cigarette was overtipped an additional five milli- meters thus blocking the holes in~the cigarette paper. The control Carlton was unchanged; however, both cigarettes were smoked to the same butt length. The results are summarized as follows: Carlton Carlton Carlton Overtipping 30 mm 30 mm 35 mm Cigarette Paper perforated Butt length~smoked yes 30 yes 38 no 38' TPMi, mg/cigt. 7.9 5 8 Nicotine, mg/cigt. 0.53 0.36 0.41 Nicotine in TPM,%; 6.6 7 5 Nicotine on Plug after smoking, mg 0.65 0.47 0,50 Number of Ports smoked 20 5 5 F-~ In another experiment, cigarettes containing,carbowax added to CA filters at the 15% level had no apparent effect onithe per cent nicotine in TPM.
