Marijuana May Ward Off Lung Cancer
Ezra Klein, reflecting on a new study finding that, “smoking marijuana, even regularly and heavily, does not lead to lung cancer” and “even a suggestion of some protective effect,” observes:
Quick thought experiment: if a martian landed on this planet, and you explained to him that there were these two types of cigarettes, one that was violently addictive and increased your susceptibility to a deadly disease by 2000%, and another that was pleasant, non-addictive, and protective against the killer ailment, which do you think our friendly neighborhood martian would theorize we keep legal?
Not to mention helping to ease the pain of treating the killer ailment.
This, of course, is a trick question. We really can’t know this without knowing the polling results in the Martian’s home district.
