Some of this book is well written, articulate and convincing. Large portions of it are repetitive drivel, restating old threadworn cliches from the sixties. It's too bad a good editor didn't realize the latter portions effectively weaken the argument for drug legalization. Obviously, many have labored to keep drugs out of the hands of the multitudes but one has to be careful when approaching the conspiracy theory. Good people over time have made some uninformed decisions that definitely ought to be re-examined in light of better evidence today. Prejudice and misconception have played their role. And, to be fair, some anecdotal evidence suggests opponents of marijuana usage sometimes may have had less than altruistic motives. But the proposition that businessmen manipulated legislation prohibiting pot smoking just don't fly.
