Pot-smokers don't necessarily quit after becoming parents

Washington D.C. [USA], Jun 2 (ANI): Marijuana-smokers often cut back after becoming parents, but they don't necessarily quit, a recent study has found. With a changing landscape for marijuana use, the research by the University of Washington's Social Development Research Group (SDRG) aimed to present information about marijuana use among parents and nonparents alike. "When it comes to adults, we don't know long-term consequences of moderate marijuana use in the legal context, so that we cannot say that we absolutely must intervene," explained lead author Marina Epstein. "However, when it comes to parents, their use is strongly related to their children's marijuana use, and that is a significant problem, since adolescent marijuana use can be harmful. Our study wanted to prepare us to build effective interventions for all adults if it becomes an issue." The study surveyed 808 adults (parents and nonparents), a group the SDRG first identified as fifth-graders at Seattle elementary schools in the 1980s as part of a long-term research project. For the marijuana study, participants were interviewed at specific intervals over a 12-year period, ending when most participants were 39 years old. That survey concluded in 2014 -- two years after marijuana was legalized in Washington. A parent-only subset of 383 people was surveyed at separate times, ending in 2011, just before the statewide vote that gave rise to pot shops. Women and people of colour made up approximately half the big study pool; of the parent subsample, about 60 percent were women, and an equivalent percentage were people of colour. The UW research found that, in general, a greater percentage of nonparents reported using marijuana in the past year than parents. At age 27, for example, 40 percent of nonparents said they had smoked pot, compared to about 25 percent of parents. By participants' early 30s, their marijuana use had declined, but a gap between the two groups remained: Slightly more than 16 percent of parents said they smoked pot in the past year, while 31 percent of nonparents reported the same. But the study also showed that participants who started using marijuana as young adults were much more likely to continue to use into their mid- to late 30s, even after they became parents. Having a partner who used marijuana also increased the likelihood of participants' continued use. Those trends were true of both parents and nonparents, demonstrating the impact of attitudes and the behavior of others, Epstein said. "This shows that we need to treat substance use as a family unit. It isn't enough that one person quits; intervention means working with both partners," she said. "We also need to tackle people's positive attitudes toward marijuana if we want to reduce use." And while the health risks to adults are being debated, the focus on children can be a driver for prevention campaigns, Epstein said. The study is published in Prevention Science. (ANI)
