Bolivian president Evo Morales recently implored the United Nations to give the coca leaf a new life. A former coca farmer himself, Morales asked the General Assembly to focus on coca's possible future as the raw material for a lucrative consumer-goods industry--not its nefarious present, as the source of the international cocaine trade. "This is the coca leaf, it is green, and not white like cocaine," Morales lectured, waving one limp little leaf at the hall of surprised dignitaries. Why, he demanded, is it "legal for Coca-Cola" but not other consumer or medicinal uses?
The largest study of its kind has unexpectedly concluded that smoking marijuana, even regularly and heavily, does not lead to lung cancer. The new findings "were against our expectations," said Donald Tashkin of the University of California at Los Angeles, a pulmonologist who has studied marijuana for 30 years. Marijuana also contains the chemical THC, which he said may kill aging cells and keep them from becoming cancerous.
