Effects of Marijuana Use on Young People

Effects of marijuana although it is a drug consumed by millions of people around the world, there are serious effects derived from the consumption of marijuana.

According to a study published April 16 in The Journal of Neuroscience, the size and shape of two brain regions related to emotions and motivation may differ in young adults who smoke marijuana at least once per Week

This study suggests that use of recreational marijuana could lead to brain changes.

Marijuana is the drug most commonly consumed in the United States and Europe. In the US alone, it consumes 18.9 million people.

Previous studies with animals have shown that constant exposure to THC – the main psychoactive component of marijuana – produces structural changes in brain regions related to motivation, attention, learning and memory.

The effects of these changes are the reduction of those capacities. However, little is known about how the low and moderate consumption of marijuana affects the brain structure  .

In the study mentioned above, Dr. Jodi Gilman, Dr. Anne Blood and Dr. Hans Breiter of Northwestern University and  Hardvard Medical College used magnetic resonance imaging (MRI) to compare the brains of boys from 18 to 25 Years who reported  marijuana use less than once a week with others of the same age who did not use the drug. The data revealed that there were significant differences; The nucleus accumbens – a brain area involved in processing the rewards – was more altered in its structure and form in marijuana users.

Dr. Carl Lupica says:

“This study suggests that even low marijuana use can produce changes in the brain anatomy .

This observation is interesting because previous studies have focused on regular marijuana users and the brain of casual users has been ignored”

Scientists found that the greater the consumption of marijuana, the greater the abnormalities in the nucleus accumbens and amygdala.

Another scientist, Dr. Breiter, says “this study is a challenge to the idea that occasional use of marijuana is not associated with bad consequences.”
