'Crack' nicotine in cigarettes varies widely

New Scientist.com


Some cigarettes have a "kick" containing 35 times more "freebase" nicotine - the most addictive form - than others, researchers have found. The findings could help rate the addictiveness of different brands, they say.

"Free-base" nicotine is a particularly potent form of the naturally-occurring tobacco drug because it is in an extremely volatile, uncombined form. This means it can be much more rapidly absorbed by the lungs and brain than nicotine derivatives such as nornicotine or its salts.
