Dear Professor Kasey:
The page is not credited and the links are invalid. But I'll investigate and see if I can deduce who might have written the text in question. Thanks.
My email is lengthy because I'm trying to combat the wrong-headed thinking of an anti-scientific Drug War that keeps botanists from doing their job.
Sorry if I overwhelmed you.
If you're ever open to persuasion on this topic -- and the need for American botanists to protest governmental restrictions on what they can and cannot research -- I invite you to visit my website devoted to such topics at abolishthedea.com.
