To access the internal IACM mailing lists and the videos, you have to be a member of the IACM.
To see the videos of the 2013 IACM Conference on Cannabinoids in Cologne please click on Videos. Please click on the talk by Raphael Mechoulam, which is for free in part, to get an impression.
I am already a member of the IACM and would like to get access to the videos. (Please note that it may need up to 24 hours or so before you receive your personal password, since we have to verify your membership.)
