Nominal machine yield

Catalog values typically refer to standardized smoking-machine measurements. They describe test output under a protocol, not an individual person’s absorbed dose.

Why exposure differs

Puff frequency, depth, ventilation blocking and product use patterns change real exposure. Lower printed yields must never be interpreted as safe or harmless.

Missing and inconsistent fields

The supplied master table provides nicotine and tar for many cigarettes but not carbon monoxide values. The atlas shows unavailable fields plainly instead of estimating them.

Source and accuracy notice

Adapted from the supplied Alcohol and Cigarettes Website Content document; numbered source markers were unresolved and are retained as internal notes rather than links.
