I don't mind if you disagree with me. I don't mind if you point out where I made an error (it happens often). However, if you feel the need to attack me personally, our discussion is over. You can't be objective if you confuse the message with the messenger.
A big thanks to all of you who made such good points or asked intelligent questions. I'm not an expert on this topic, and my thinking is limited to one particular corner of the issues, the scientific data on health effects. Outside that realm, my opinion is no better (or worse) than anyone else.
I'm quite prepared to admit when I've allowed bias to affect my analysis. I hope some of you will do the same. To be honest, I didn't realize that wanting to see less drug usage was a bias. I'd like to see less cigarette smoking, less alcohol abuse, less pot smoking and fewer people smoking crack or shooting up heroin. I didn't realize that was a controversial bias. I didn't quite grasp that some people think MORE people smoking pot was a good thing. I don't see these apologists for other drugs.
