As marijuana continues to be decriminalized across the United States, the dangers of children obtaining and using the drug are also coming into light. Now, a recent study shows how adolescent cannabis use could change the way neurons function in certain areas of teens’ brains, specifically the regions behind decision-making, planning, and self-control.

The study, conducted by the University of Illinois at Chicago psychologists, used an animal model of the structural development of the prefrontal cortex (PFC), which controls all high-level cognitive functions.

Within the prefrontal cortex, there is a support structure called the perineuronal net, which forms a type of protective shield using proteins around inhibitory cells. This helps secure the cells’ connections with excitatory neurons and regulate overall PFC activity. Scientists know that perineuronal net formation can be influenced by narcotic use, but the specific effects of marijuana are not yet known.

In the study, researchers gave adolescent rats a synthetic cannabinoid substance similar to the main psychoactive ingredient in cannabis, THC. The rats were administered this substance for either one day, ten days, or ten days followed by a period of abstinence. Then, the perineuronal net structures in these rats were compared to other animals who hadn’t received any synthetic THC.

Rats that were exposed to the synthetic cannabinoid exhibited reduced development around inhibitory cells during adolescence. The researchers also found that this reduction was more prominent among male rats.

“Our evidence suggests that exposure to cannabinoids during adolescence alters brain maturation in the prefrontal cortex,” says study leader Eliza Jacobs-Brichford in a university release. “These results may offer a mechanistic explanation for functional and behavioral changes caused by adolescent cannabinoid exposure.”

Teen girls who play several sports have a lower injury risk than those who focus on just one, a new study finds.

It included more than 1,100 girls who play basketball, soccer, and volleyball. Most were middle and high school students; some were in college.

Girls who specialize too early in sports such as basketball, soccer and volleyball could find that a single-minded focus "may hinder motor development and lead to compromised hip and knee coordination during dynamic landing and jumping activities, which can lead to increased chance of potentially life-altering injuries," said lead author Christopher DiCesare. He's a biomechanist in the Division of Sports Medicine at Cincinnati Children's Hospital Medical Center in Ohio.

The study also found that girls who focused on a single sport had a higher rate of hip and knee injuries and an increased risk of knee pain.

Researchers said playing multiple sports may improve girls' coordination, and that those who specialize may not fully develop neuromuscular coordination patterns that can reduce the risk of injury.

Due to uneven growth in bone mineral and muscular and connective tissue strength before and during puberty, young athletes may be less able than older ones to handle the physical stresses associated with focusing on one sport, the study published in the Journal of Athletic Training concluded.
