In the Internet era, members of the general public have unprecedented access to scientific facts and figures. Among the resources now available at one’s fingertips is the National Center for Biotechnology Information database. NCBI is an NIH.gov electronic search engine that allows the public to instantly read the abstracts of hundreds of thousands of peer-reviewed scientific papers on virtually any subject, including an estimated 20,000 papers on cannabis alone.
So why then does the head of the National Institutes of Health purport to know so little about the science of pot?
Speaking publicly last week at a dinner hosted by USA Today and National Geographic, NIH director Francis Collins—known as one of the nation’s top scientists for his leadership of the international Human Genome Project—acknowledged that pot isn’t necessarily “an evil drug that’s going to ruin our civilization.” Nevertheless, he expressed a surprising lack of familiarity with much of the readily available research that has been conducted on the plant and its impact on those who consume it.
“We don’t know a lot about the things we wish we did,” with respect to the herb, Collins said, seemingly unaware that a keyword search of the agency’s own sponsored website would yield thousands of scientific papers specific to marijuana and its behavioral and health effects. “I’ve been asked repeatedly, does regular marijuana smoking, because you inhale deeply, increase your risk of lung cancer? We don’t know. Nobody’s done that study.”
Wrong. In fact, the largest case-controlled study ever to investigate the respiratory effects of marijuana smoking reported that cannabis use was not associated with lung-related cancers, even among subjects who reported smoking more than 22,000 joints over their lifetime. Summarizing the finding of the NIH-funded study to the Washington Post, lead investigator and pulmonologist Donald Tashkin of UCLA affirmed, “We hypothesized that there would be a positive association between marijuana use and lung cancer, and that the association would be more positive with heavier use. What we found instead was no association at all, and even a suggestion of some protective effect.”
