The Union is a 2007 International-Award-Winning Canadian Documentary that centres
on marijuana prohibition and the BC System that infects every single walk of life,
despite being illegal, which is nicknamed "The Union", since it involved the trust
and participation of everyone, knowingly or unknowingly, in the economic system of
Marijuana. It explains the ultimate stimulation of every single career and job,
including those who are against The Union and Marijuana. It also goes very
in-depth on The Drug War in Canada and the United States, and tries to figure out
how it remains illegal, and why legalization is the ultimately best option for
everyone. The BKS Crew researched and made the movie over 2 years.
There is a large number of interviews, including those who require marijuana for
medical reasons, doctors, former RCMP and American Police officers, some TV stars,
everyday people, "criminals" who've been jailed for possession, and more.
Here is a list of Interviews:
