Nondaily Smokers Who Switch to 22nd Century's Very Low Nicotine Content Cigarettes Reduce their Consumption by a Staggering 51%

22nd Century Group, Inc. (NYSE American: XXII),
a plant biotechnology company that is a leader in tobacco harm reduction
and Very Low Nicotine tobacco, announced today that an independent
clinical trial
published this summer in JAMA Psychiatry (a
specialty journal of the American Medical Association) found that
nondaily smokers who switch to 22nd Century's proprietary Very Low
Nicotine Content (VLNC) cigarettes "reduced their smoking by 51%."

In conducting this important clinical trial, study authors Saul
Shiffman, Ph.D., Brenda Kurland, Ph.D., Sarah Scholl, MPH, and Jason
Mao, B.S. used 22nd Century's proprietary SPECTRUM® VLNC cigarettes and
standard nicotine content cigarettes. The 12-week, randomized,
controlled, double-blind intervention trial enrolled 297 adult U.S.
smokers who do not smoke daily; this clinical trial is the first
published study to focus on occasional (nondaily or "intermittent")

Intermittent smokers assigned to VLNC cigarettes reduced both the
overall number of cigarettes smoked and the number of days on which they
smoked. Reporting that 25% to 33% of all U.S. smokers do not smoke daily
(intermittent smokers), Dr. Shiffman, et al. believe that this
substantial fraction of the smoking public must be included in all
tobacco policy considerations.

The researchers reported that their study results did not vary by sex or
race/ethnicity. Dr. Shiffman, et al. reported further that their
study results "mitigate concern that intermittent smokers might increase
smoking when switched to Very Low Nicotine Content cigarettes," and that
intermittent smokers "respond to Very Low Nicotine Content cigarettes in
a manner similar to daily smokers, suggesting that a universal policy
[by FDA] is possible."

"The Shiffman clinical study shows that when nicotine is largely absent
from cigarettes, occasional smokers – just like daily smokers – consume
drastically fewer cigarettes," explained Henry Sicignano, III, President
and Chief Executive Officer of 22nd Century Group. "22nd Century is
proud to be at the center of a national policy initiative designed to
ensure that all cigarettes sold in the United States are minimally or
non-addictive; it is imperative that we take this important step to
prevent millions of today's youth from becoming addicted to cigarettes."
