Here is a fascinating discussion on NPR’s Forum from earlier this year on the subject of mercury and fish:

If you’ve listened to this the whole way through (which you should), I’m curious as to how it will affect your habits, if at all.  And why?

What’s fascinating to me about this is not that it works so well and or that there might actually be support in the Obama administration for doing it on a national scale, but rather that there has not been a backlash against it yet.  What are the odds that something like this will actually get implemented?  Is it actually a good thing?

Thanks to a pointer from Sandeep Baliga over at Cheap Talk, I recently Kindled Matthew Alexander’s How to Break a Terrorist. If this were a novel, it would be in the top 10% of thrillers I’ve read in the last 5 years.  But it’s a true story.

Unfortunately, Gash oversimplifies the game to just one round. In reality, Afghan villages participate in multiple rounds of decision making, with the actual number of rounds unknown, leading to differing strategies and outcomes than those proposed by Gash.

Many users, and friends of users of marijuana report experiencing a “contact high.” That is, they purport to experience some of the effects of marijuana simply by being in contact with or around those using marijuana. Virtually all users wrongly attribute this experience to the inhalation of second hand smoke. This is unlikely for a number of reasons. Since exhaled smoke is virtually devoid of psychoactive substances and is widely dispersed in the surrounding air, it is not possible for one to inhale even a small fraction of a working dose. Additionally, many, including noted pharmacologist and psychedelic researcher Alexander Shulgin, report similar experiences involving drugs that are not inhaled, indicating that these effects are due to different biological processes.
