Mass General Brigham researchers scrutinized this concern with the first-ever study comparing substance use disorder rates in patients with ADHD who were prescribed stimulant medications during in-person versus virtual appointments. They found that, overall, telehealth was not associated with increased risk of substance use disorder. Still, the researchers noted the importance of comprehensive diagnoses and routine follow-ups.

Researchers have developed a way to use fruit flies to explore the genetic underpinnings of cocaine addiction.

Marijuana use among older adults in the US has reached a new high, with 7 percent of adults aged 65 and over who report using it in the past month, according to an analysis led by researchers with the Center for Drug Use and HIV/HCV Research (CDUHR) at the NYU School of Global Public Health. 

A new study led by UC San Francisco researchers finds that chronic cannabis use — whether it’s smoked or consumed in edible form — is associated with significant cardiovascular risks. 

Using a novel lab method they developed, McGill University researchers have identified nine molecules in the blood that were elevated in teens diagnosed with depression. These molecules also predicted how symptoms might progress over time.

The findings of the clinical study could pave the way for earlier detection, before symptoms worsen and become hard to treat.
