As stated in our third tradition, the only requirement for membership in Marijuana Anonymous is a desire to stop using marijuana. There is no mention of any other drugs or alcohol. This is to adhere to the “singleness of purpose” concept, but many of us have found that the only way that we can keep our sobriety is to abstain from all mind and mood altering chemicals, including alcohol.
When we give up the drug of our choice, a void is created. The initial struggle to abstain from marijuana use often leaves us vulnerable. To fill this voidwe may start to use, or increase the use of, other substances such as alchohol, cocaine, pills, or other self-prescribed drugs. Although we may noe be addicted to these substances, their use can lower our inhibitions, leaving us open to repeating old patterns of thinking and behaving than can lead back to marijuana use. The fact that we bacame addicted to marijuana reflects a tendency towards behavior that may lead to cross addiction or substitution addiction to these substances.
