The positive associations of antisocial behavior/deviant peer association and volume of use in high school would also indicate that limiting associations and unsupervised time with deviant peers should also have preventive effects. Finally, strategies to prevent growth in antisocial behavior in childhood may also be expected to reduce the risk of any use and in growth of volume of use of alcohol in adolescence. Given the high costs to society of adolescent alcohol use, this indicates the value of further preventive efforts in these directions.
