The sampling technique used in the study was non probability purposive sampling and sample size of 60 alcoholic adult males (Above the 18 years). Result: The analysis reveals that post-test mean knowledge score value whish was higher 16.95 with SD of ± 2.09 when compared with pre-test mean knowledge score value which was 6.08 with SD of ± 2.35. The calculated t-value 31.43 is greater than table value 2.00 at 0.05 level of significance. Thus the H1 is accepted and H0 is rejected.
