I smoke weed every day. Have been for awhile. I can say that I have noticed changes mentioned in this article and I'll be limiting myself with the marijuana usage.
Casual marijuana use linked to brain changes
"Just casual use appears to create changes in the brain in areas you don't want to change," said Hans Breiter, a psychiatrist and mathematician at the Northwestern University Feinberg School of Medicine in Chicago, who led the new study.
There is actually very little research on the potential benefits and downsides of casual marijuana smoking — fewer than four times a week on average.
In his study, done in collaboration with researchers at Harvard University, scientists looked at the brains of 20 relatively light marijuana users and 20 people who did not use it at all. All 40 were college students in the Boston area.
The study found volume, shape and density changes in two crucial brain areas — the nucleus accumbens and the amygdala — involved with emotion and motivation and some types of mental illness. "This is a part of the brain you do not want to mess around with," Breiter said.
The more marijuana the students smoked, the more their brains differed from the non-users, the study found.
The brain continues to develop well into the 20s, and even into the 30s, said Breiter, who is concerned about the long-term impacts of marijuana use on the developing brain.
