A statistical meta-analysis of 198 independent treatment outcomes found
that the Transcendental Meditation program produced a significantly larger
reduction in tobacco, alcohol, and illicit drug use than standard substance
abuse treatments and prevention programs. The meta-analysis controlled
for strength of study design and included both heavy and casual users.
Whereas the effects of conventional programs typically fall off rapidly
within 3 months, effects of the TM program increase over time. Total abstinence
from tobacco, alcohol, and non-prescribed drugs ranged from 51% to 89%
over an 18-22 month period. The effects of the TM program are based upon
fundamental and naturally occurring improvements in mind and body. (Alcoholism
