Released: December 4, 2018. In a small study of infrequent cannabis users, Johns Hopkins Medicine researchers have shown that, compared with smoking cannabis, vaping it increased the rate of short-term anxiety, paranoia, memory loss and distraction when doses were the same.

Seeking Knowledge to Cure and Prevent

Our clinical research programs range from efficacy and treatment-response studies to clinical trials and epidemiology. Our basic research encompasses bioinformatics, genetics, neuroscience, neuroimaging, and molecular biology - all in an effort to unlock the causal pathways to the major psychiatric conditions and to use this knowledge to develop practical means to improve diagnosis and treatment.

More than 100 years of research on familial bipolar disorder hasn’t revealed much about its specific genetic causes. But all that’s about to change, says psychiatric epidemiologist Peter Zandi thanks to advances in genome data analysis and sequencing—and access to human brain samples to tease out clues. “Our goal,” says psychiatrist Fernando Goes “is to find etiologic clues that will ultimately lead to new, urgently needed, targeted drugs.”
