The Tenth Tradition of Marijuana Anonymous states:
Marijuana Anonymous has no opinion on outside issues; hence the MA name ought never be drawn into public controversy.
This tradition protects the integrity of the organization. From Marijuana Anonymous’ book Life with Hope, page 93:
Anything that can disrupt our unity, and interfere with our primary purpose of carrying the message to the marijuana addict who still suffers, should be avoided.
Therefore, MA has no opinion about the legalization of marijuana.
