A headline on Page A4 of your print edition, “Study will test use of marijuana for epilepsy” (April 14), is incorrect and misleading.

The study is not testing marijuana. It is testing a chemical derivative of marijuana called cannabidiol, as is explained further in the article. However, some people will not read beyond the headline, and, if so, they will be misled.

For those wanting more information about the present medical, legal and policy status of marijuana, I recommend a recently published book: “Marijuana: The Unbiased Truth About the World’s Most Popular Weed” by Kevin P. Hill, M.D.

I learned a lot from it and believe it really is unbiased in its presentation, unusual as that may be these days.
