A new study by Chicago’s Northwestern University found that teens who use marijuana heavily grow up to have poor memories and also have brain abnormalities, suggesting there could be long-term effects of heavy marijuana use. 

Researchers evaluated 97 volunteers with and without some sort of a mental illness. The people surveyed said they'd used marijuana daily starting at age 16 or 17, and said they had not used other drugs.

For several years, people in the Pavas district of Costa Rica were experiencing an increase in crime and in youth marijuana use. But after a coalition was formed, thanks to the training and assistance from CADCA, local citizens developed a planning process and began implementing evidence-based prevention strategies.

CADCA began working in the Central American country in 2013 to help concerned citizens in Pavas form a community coalition. Located within the greater metropolitan area of the capital city of San Jose, Pavas is the largest and most populated district in Costa Rica.

This week, the United Nation’s Office on Crime and Drugs’ Global SMART (Synthetics Monitoring: Analyses, Reporting and Trends) Program released a progress report on international synthetic drug use, which illustrates the widespread use of synthetic cannabinoids around the world.

Synthetic cannabinoid receptor agonists, commonly referred to as synthetic cannabinoids, constitute the largest, most diversified and fastest growing group of NPS on the market, the report said.

By harnessing the power of the community, a coalition in Arizona has consistently decreased rates of youth alcohol, marijuana, tobacco and prescription drug use over the past four years.

For the first time in U.S. history, all nine former Administrators of the Drug Enforcement Administration (DEA) today filed an amici curiae brief urging the Supreme Court to consider and stop what they see as the damage being done by fracturing a carefully constructed national system of drug control—the legalization of marijuana by Colorado.

The former Administrators believe that Colorado’s law legalizing the large-scale cultivation and sale of marijuana, not only is causing great harm to neighboring states, but is in direct conflict with federal law.

Today, all nine former Drug Enforcement Administration (DEA) administrators filed an amicus brief urging the U.S. Supreme Court to hear the federal lawsuit against the State of Colorado, being brought by neighboring states Nebraska and Oklahoma. CADCA stands with these experts in asking that the United States Supreme Court hear this case.

Researchers at Washington University School of Medicine in St. Louis, Mo. have found that the "Twitterverse" is a pot-friendly place. Analyzing every marijuana-related Twitter message sent during a one-month period in early 2014, more than 7 million tweets referenced marijuana, with 15 times as many pro-pot tweets sent as anti-pot tweets.

The findings were reported online Jan. 22 in the Journal of Adolescent Health and will appear in February in the journal's print edition.

Half of teens and young adults who died in car crashes in nine states were under the influence of either alcohol or marijuana, or both, according to statistics of fatal road accidents involving 16- to 25-year olds between 1999 to 2011.

Researchers at Columbia University’s Mailman School of Public Health analyzed the statistics to gauge how possible policy changes could influence substance use among teens and young adults. The study, led by Katherine M. Keyes, PhD, assistant professor of Epidemiology, was published online in the journal Injury Epidemiology.

Youth marijuana use is one of the most pervasive problems in communities today. To help coalitions address this in a comprehensive manner, CADCA has put together a wide range of marijuana-focused training sessions at its upcoming 25th annual National Leadership Forum, held Feb. 2-5 in National Harbor, Md.

Coalition members have their choice of attending seven courses related to marijuana-use prevention.
