Variation of smoke yields (mg per cigarette) of machine-rolled cigarettes with conditioning interval at standard environmental conditions
| Interval (hours) | CO | Nicotine | Tar |
|---|---|---|---|
| <8 | 23.2 (2.1) | 2.68 (0.29) | 36.5 (2.6) |
| 20 | 24.0 (1.1) | 2.98 (0.11) | 36.1 (1.5) |
| 44 | 23.3 (1.5) | 3.12 (0.18) | 35.9 (2.5) |
All results are the mean yields for four determinations (sample standard deviations in parentheses). Cigarettes were conditioned for the tabulated intervals at 22°C and 60% relative humidity before machine smoking.
CO = carbon monoxide.
