Yeah, but...

No fair just quoting the "laboratory" results. In the real world, the
DELIVERY system is everything.

The human lung is made to process AIR, not smoke...and it has been
proven conclusively time and again that smoking (of any substance)
CAUSES cancer...and emphysema...and cardiovascular problems...and a host
of other ills.

So, nice self-serving rationalization, but no cigar.


Then why is there no elevated cancer rate among chronic pot smokers? No
cigar but perhaps a blunt?

"People who smoke marijuana do not appear to be at increased risk for
developing lung cancer, new research suggests.

While a clear increase in cancer risk was seen among cigarette smokers
in the study, no such association was seen for regular cannabis users.

Even very heavy, long-term marijuana users who had smoked more than
22,000 joints over a lifetime seemed to have no greater risk than
infrequent marijuana users or nonusers.

The findings surprised the study’s researchers, who expected to see an
increase in cancer among people who smoked marijuana regularly in their
youth.

“We know that there are as many or more carcinogens and co-carcinogens
in marijuana smoke as in cigarettes,” researcher Donald Tashkin, MD, of
UCLA’s David Geffen School of Medicine tells WebMD. “But we did not find
any evidence for an increase in cancer risk for even heavy marijuana
smoking.” Carcinogens are substances that cause cancer.

Tashkin presented the findings today at The American Thoracic Society’s
102nd International Conference, held in San Diego.Boomers Reaching
