influences husband's marijuana use - study
July 20, 2005 (Reuters) - A newlywed wife can help
determine whether her husband smokes marijuana, U.S.
researchers said on Wednesday.
The researchers found that when people in
their 20s first marry, husbands are more likely to start or
resume smoking marijuana if their wives smoke it, and are
more likely to stop smoking marijuana if their spouses do
But husbands had little influence on
whether their wives used marijuana, the team at the
University at Buffalo's Research Institute on Addictions
"For both social drinking and smoking
marijuana, wives influence husbands' use from the first to

"Although wives influence husbands'
marijuana use from before marriage to the first anniversary,
they did not influence husbands' heavy alcohol use during
Writing in the Journal of Drug Issues, the
researchers said they studied 634 couples, 471 of whom
provided data before marriage, at their first anniversary
and at their second anniversary. They were in their late 20s
"In this study, we found that the
prevalence of marijuana use decreased for both men and women
over the first year of marriage," Leonard said.
"For men, use decreased from about 25
percent to 21 percent from the year before marriage through
the first year of marriage, and for women over the same
period, from 20 percent to 14 percent."
Smokers were often married to other
"We identified one direction of influence,
that is, wives influenced their husbands' initiation of
marijuana use, but husbands did not influence wives' use,"
The first year of marriage may be a unique
time for setting the ground rules for a relationship,
Leonard said, citing other studies.
"Substance use tends to decline as
individuals progress through their 20s," he said.
"This may be a part of the maturing
process, but it also reflects periods of transition in life,
such as marriage with its increased responsibilities."
