Marijuana is now officially out in the sunshine in Oregon and California, legal to grow and legal to use. But that doesn't mean the practices that developed to make and market cannabis during the prohibition years have changed.
Journalist Nick Johnson demonstrates how the industry continues to use old, environmentally damaging practices even though the purported reasons for them no longer exist.
Johnson's book is Grass Roots: A History of Cannabis in the American West, from Oregon State University Press. The author visits with details of a story that dates back--in America--to the mid-19th century.
