The use of cannabis in the U.S. has undergone a dramatic change over the past two decades.  Starting with the campaign to legalize the use of cannabis in the 90s, use, attitudes and risk perception have changed in both adolescent and adult population.  In this presentation, four recent research publications will be reviewed that highlight a more cautious approach towards cannabis.

  • First, a rare experimental study with cannabis available to purchase researchers show that the high concentration of THC, one of the key ingredients of the cannabis plant which can be found in high concentration in concentrates is associated with significant cognitive performance deficits.
  • Second, using a large observational data set researchers found that there was a higher risk of – among other psychiatric conditions – anxiety in those individuals who used high-potency cannabis strains.  
  • Third, using the entire population of Denmark researchers estimated the proportion of cases of schizophrenia that is attributable to cannabis use disorder and found a significant increase from 4-5% in the 1990s to 8% since 2010.  
  • Fourth, analyzing the Adolescent Brain Cognitive Development (ABCD) data, researchers found that youth whose mothers used cannabis during pregnancy relative to those that did not show more psychological and cognitive problems at age 9-10.  

Taken together, these recent publications need to be considered when one decides to use cannabis or need to be balanced against potential beneficial effects of cannabis.

Martin Paulus, PhD, Scientific Council Co-Chair

Member Since 2008

Dr. Paulus is the Scientific Director and President of the Laureate Institute for Brain Research (LIBR) in Tulsa, OK. Dr. Martin Paulus joined the Laureate Institute for Brain Research (LIBR) in Tulsa, Oklahoma as the Scientific Director and President in May 2014. Prior to this transition, he had been a Professor in the Department of Psychiatry at the University of California San Diego (UCSD) and the Director of Telemental Health at the Veterans Affairs San Diego Health Care System (VASDHS). Dr. Paulus had been at UCSD since arriving as a postdoctoral fellow in 1986 and has been funded continuously by the NIH since 1997. LIBR focuses on using neuroscience approaches to develop better assessments for diagnosis or prognosis of mental health problems and to develop neuroscience based novel interventions. Dr. Paulus' research focuses on pragmatic academic psychiatry, i.e. how to use neuroscience-based measurements to generate individual level predictions that can be useful for clinicians. Moreover, Dr. Paulus is interested in whether computational approaches can be useful to better develop explanatory basis for psychiatric disorders that can be submitted to rigorous scientific examination. In particular, Dr. Paulus is interested whether individuals with increased levels of anxiety have difficulty differentiating random fluctuations from probabilistic but useful information. Dr. Paulus is the co-chair of the ADAA Scientific Council and ex-officio board member.

Dr. Paulus and ADAA

"Murray Stein told me a long time ago 'I will make you into an anxiety researcher' and I think he succeeded and I am very happy about it too. My first ADAA meeting was in Saint Louis in 2007 and I have been coming every year ever since. ADAA is a natural home for high quality research in mood and anxiety disorders and provides the unique opportunity to connect with clinicians and those affected by mood and anxiety disorders."
