Opponent was willing to wing it on evidence

“[M]arijuana is a gateway, I don’t care what any study shows …”

This line effectively sums up Dan DeWitt’s Jan. 3 commentary “Marijuana use dulls the mind.” While well-outfitted with DeWitt’s personal experience, the article offered only limited evidence: a comparison of test scores and marijuana use in high schoolers, which is correlational at best. What’s more, the two measurements he compared were taken 14 years apart! He even rejected hard evidence, not only in the quote above, but by reiterating the old claim that marijuana causes brain damage, which has never been established in adults.

If I read an article titled “Marijuana use dulls the mind,” I expect evidence of that.



The Dec. 30 “You Don’t Say” cartoon incorrectly named the source of the quotation portrayed. It is James Branch Cabell.
