Should runners be "Dazed and Confused?" The debate over runners smoking pot to improve performance

In the February 9, 2014, Wall Street Journal, http://www.wsj.com/articles/the-debate-over-running-while-high-1423500590?mod=e2fb writer Frederick Dreier interviews several runners to ask about their using pot during and after races.

Not surprisingly, the evidence of its positive effects are anecdotal at best. Yes, pot is helpful in battling nausea experienced by cancer patients and it does encourage eating. But does that translate to a better running performance? Pretty unlikely would be my opinion. As a runner in high school beginning in the fall of 1969 and graduating in the spring of 1974, smoking pot was very popular in my high school. Did I ? No-for the same reason that I didn't smoke cigarettes, I didn't want any smoke going into my lungs. I instinctively knew that bad lungs equals a slower runner.

But, whatever floats your boat, man.
