This study compared 18 low-risk drinking guidelines that were gathered
from Canadian government agencies, non-government agencies, medical b
odies, and public and private agencies involved in the treatment of ad
dictions. The results show that two sets of guidelines are predominant
ly used in Ontario. The formulation of these guidelines was entirely i
ndependent and their intended audiences are also different. However, a
direct comparison of the two guidelines shows that differences are mo
re apparent than real. This study also examines the literature evaluat
ing low-risk drinking guidelines. Very little literature exists on eva
luating low-risk drinking guidelines as vehicles for primary preventio
n and it is not known to what extent such guidelines influence knowled
ge and drinking behaviour. Future low-risk drinking recommendations sh
ould be evaluated for knowledge about standard drink units, awareness
of the guidelines, use of materials and aids included in the dissemina
tion program, and changes in behaviour from campaign exposure.
