Calls to Colorado poison control centers seeking help for unintentional marijuana exposure in children younger than age 10 jumped 150 percent since 2009, a new study in JAMA Pediatrics found.

In that same year, the state commercialized marijuana for medical use. Rates soared again in 2013 when the state legalized recreational marijuana.

A new report by the Substance Abuse and Mental Health Services Administration (SAMHSA) shows that rates of marijuana use and perceptions of risks of harm associated with marijuana use vary significantly among regions of the country and even within states. The SAMHSA report uses detailed tables and color coded maps to present estimates for smaller areas within states (sub-states), which provide a more detailed look at these issues within states and throughout the nation.

According to a recent study conducted by University of Michigan researchers, long-term marijuana usage is associated with a decrease in the brain's response time. The study, published in JAMA Psychiatry, brought forth new information about the effect marijuana can have on the brain of a young adult user.

To determine whether marijuana use among young adults prospectively affects nucleus accumbens (NAcc) activation during reward anticipation.

The likelihood adolescents will try marijuana rises steadily from age 11 to age 16, then decreases before hitting another peak at age 18, according to a new University of Florida study.

As more and more states legalize marijuana, coalitions will want to be armed with the latest information to prevent youth use and impaired driving. Obtain these strategies and metrics on the topic at CADCA’s 15th annual Mid-Year Training Institute at The Mirage Hotel in Las Vegas July 17th-21.

A new study found that one in six infants and toddlers admitted to a Colorado hospital with coughing, wheezing and other symptoms of bronchiolitis tested positive for marijuana exposure.

In a recent study, researchers found evidence of a compromised dopamine system in heavy users of marijuana. Lower dopamine release was found in the striatum–a region of the brain that is involved in working memory, impulsive behavior, and attention. Previous studies have shown that addiction to other drugs of abuse, such as cocaine and heroin, have similar effects on dopamine release, but such evidence for cannabis was missing until now.

Being a youth leader is SRSLY the best honor ever for Ananth Ghosh. The high school student was honored by CADCA recently as its 2016 Outstanding Youth Leader.

The Outstanding Youth Award recognizes an outstanding young person for service to a coalition and preventing substance abuse.

Ananth, 17, accepted his award during CADCA’s 26th annual National Leadership Forum to a standing ovation. He told the crowd of coalition leaders about how he was bullied as an elementary school student and applied his insecurity into action.

On behalf of CADCA’s 5,000 community coalitions across the country, we commend Sen. Charles Grassley (R-Iowa) and Sen. Dianne Feinstein (D-Calif.) for holding the Drug Caucus hearing yesterday on “Is the Department of Justice Adequately Protecting the Public from the Impact of State Recreational Marijuana Legalization?”
