Dr. Staci Gruber, director ..., 16 April 2014 [cached]
Dr. Staci Gruber, director of the Cognitive and Clinical Neuroimaging Core at McLean Hospital in Boston and a professor of psychiatry at Harvard Medical School, has conducted numerous studies on marijuana use and brain function.
"This data certainly confirms what others have reported with regard to changes in brain structure," she said. "When we consider the findings of the Gilman ... study with our own and other investigations of marijuana use, it's clear that further investigation is warranted, specifically for individuals in emerging adulthood, as exposure during a period of developmental vulnerability may result in neurophysiologic changes which may have long-term implications."
Gruber says we need to take a closer look at all pot users whether they smoke once or twice a week or four or time times a week.
And she had this advice for adolescents: "Don't do it early--prior to age 16.
Pot Said to Damage Young Users’ Brains, 16 Nov 2010 [cached]
Research on how marijuana changes a developing brain is important as it's the most frequently used illegal drug in the United States, said study author Staci Gruber, the director of the neuroimaging center at McLean Hospital in Belmont, Mass. Almost 16 percent of eighth graders have tried marijuana, and that number rises to 42 percent by 12th grade, a 2009 study from the National Institute on Drug Abuse found.
Chronic, early users of marijuana "make repetitive incorrect responses despite the fact I'm telling them they're wrong," said Gruber, who is also an assistant professor of psychology at Harvard University. "That's called 'cognitive inflexibility' and you see it in babies."
The research, presented yesterday at the Society for Neuroscience's meeting in San Diego, also found that the group that started earlier smoked more pot more often than those who started later. People who began smoking before age 16 had 25.1 smokes a week, compared with 12.1 in those who began later, the study showed. The early-onset group smoked almost three times as many grams a week, Gruber said.
The research didn't examine those people who had started smoking early and stopped, although those people begin to look more like non-smokers in other studies, Gruber said.
"The developing brain is vulnerable," Gruber said.

In a paper that will be presented on Monday, Nov. 15 at the annual meeting of the Society for Neuroscience in San Diego, Staci A. Gruber, PhD, reported that subjects who started using marijuana before age 16 made twice as many mistakes on tests of executive function, which includes planning, flexibility, abstract thinking and inhibiting inappropriate responses as those who began smoking after age 16.
"They performed significantly worse," said Gruber, director of the Cognitive and Clinical Neuroimaging Core at McLean and assistant professor of Psychiatry at Harvard Medical School.
The early-onset users also smoked three times as much marijuana per week and twice as often compared to the later-onset users, she noted.
"Our data suggest that the earlier you begin smoking, the more marijuana you smoke and the more frequently you smoke," she said. "That's an important finding."
Gruber said the findings are particularly critical today when legalization of marijuana is being considered in a number of states.
"We have to be clear about getting the message out that marijuana isn't really a benign substance," she said.
"Our results provide further evidence that marijuana use has a direct effect on executive function and that both age of onset and magnitude of marijuana use can significantly influence cognitive processing," said Gruber.
"Given the prevalence of marijuana use in the United States, these findings underscore the importance of establishing effective strategies to decrease marijuana use, especially in younger populations," she said.
Staci Gruber, an associate ..., 16 April 2014 [cached]
Staci Gruber, an associate professor of psychiatry at Harvard Medical School, told USA Today this week that the new results rang true to her research. "There have been a growing number of studies that suggest that marijuana use in emerging adults is associated with differences in brain structure and cognitive abilities," Gruber said.
Young people "don't think it's risky," ..., 6 Oct 2012 [cached]
Young people "don't think it's risky," explained Staci Gruber, a researcher at the Harvard-affiliated MacLean Hospital in Belmont, Mass. told the Huffington Post in an interview. However, the idea that marijuana harms the adolescent brain, Gruber explained, is something they believe is very likely.
