Hello all. I was looking around the net last night for some info and found this website from the public health agency of Canada, and was quite impressed with how unbiased it is. http://www.canadian-health-network.ca/servlet/ContentServer?cid=1052490786377&pagename=CHN-RCS%2FCHNResource%2FCHNResourcePageTemplate&c=CHNResource It mentions that almost all harm associated with use is because of the actual burning of materials, and mentions harm reduction rather than strict "just say no" BS when dealing with your children. Even the links are pretty informative and free of propaganda. Proud to be Canadian.
