From the HACNA Guidelines: This body shall be known as the Houston Area Convention Committee of Narcotics Anonymous and shall operate as an ad hoc subcommittee of the Houston Area Service Committee. The purpose of this body shall be to coordinate and conduct a bi-annual Houston Area Convention by members of Narcotics Anonymous to bring our membership together in the celebration of recovery and unity. Meetings, workshops, marathon meetings and other activities are scheduled to encourage unity and fellowship among our members. Because service committees of Narcotics Anonymous sponsor conventions, they shall always conform to the N.A. principles and reflect our primary purpose: to carry the message of hope to the addicts who still suffer. Any member of Narcotics Anonymous may participate on the Convention Committee.
