Studies on controlled drinking have found that​

A) ​no true alcoholics can be trained to resume normal drinking.
B) ​all subjects were functioning well after three years.
C) ​abstinence-oriented programs sometimes produce controlled drinkers.
D) ​participants trained to abstain were more likely to be successful than those trained to control their drinking.

Studies on controlled drinking have found that abstinence-oriented programs sometimes produce controlled drinkers. This means that some individuals who originally had a problem with alcohol may be able to control their drinking after going through an abstinence-oriented program. However, it is important to note that this may not be true for all individuals and abstinence is still widely considered the most effective approach for those with alcohol use disorders.
