I love charts. These two are interesting. Perhaps one activity drives the other. I keep looking for some correlation but it may just be coincidence. The chart above plots consumer confidence levels in the U.S., and the last nine months has been a race to the bottom. And this chart doesn't even reflect the events of the past two weeks.
The chart below compares usage rates for both marijuana and cocaine among 17 industrialised nations. Finally -- something in which America can still claim worldwide leadership!
