In a new study, researchers found “social host” laws that hold adults responsible for underage drinking on their property have reduced the number of teenage weekend drinking parties.
Over the years, a variety of such laws have been enacted in many U.S. states and local communities, but prior research has been mixed as to whether they actually keep kids from drinking.
In the new study, found in the Journal of Studies on Alcohol and Drugs, investigators focused on 50 communities in California, half of which had social host laws. California as a state has no law on the books, but local governments are free to devise their own.
The researchers found that teenagers were less likely to report drinking at parties when they lived in communities with particularly strong social host laws.
However, the findings indicate a correlation and not necessarily a direct effect of the laws, said lead researcher Mallie J. Paschall, Ph.D., a senior research scientist at the Prevention Research Center in Oakland.
“These findings are preliminary. We can’t say that social host laws definitely prevent kids from drinking at parties,” Paschall said.
Still, the results are encouraging, according to Paschall.
“Most kids get alcohol from social sources, not commercial ones,” he pointed out. So, in theory, laws aimed at those social sources — in this case, parents or other adults of legal drinking age — should help reduce underage drinking.
“It does look like there is less-frequent drinking among teenagers in cities with stringent social host laws, even when other city and youth characteristics that are related to underage drinking are controlled for,” Paschall said. “So these laws might be an effective strategy for reducing hazardous drinking.”
“Strong” social host laws have some key provisions, according to Paschall:
- They specifically target underage drinking;
- There is a civil penalty (such as a hefty fine) that is swiftly administered;
- Property owners are held responsible, even if they claim they didn’t know about the underage drinking.
Paschall acknowledges that the laws are often controversial. Further, in some communities, police do not enforce the laws, sometimes because there is little support for the policies from the public or the local prosecutor’s office.
Enforcement is necessary for the laws to work although public knowledge of the laws may be a greater force to restrain underage drinking.
“If adults don’t know they could be held responsible for underage drinking, the policies won’t be much of a deterrent,” said Paschall.
In future studies, the researchers plan to look at rates of teen drinking before and after the passage of social host laws to get a better idea of whether the policies themselves have an impact.
Paschall said it will also be important to see whether the laws reduce problems related to teen drinking, including drunk driving.
