Joseph M. Pierre, MD Biography

Title:
Co-Chief of the Schizophrenia Treatment Unit at the Veterans Administration (VA) West Los Angeles Healthcare Center
Position:
Not Clearly Pro or Con to the question "Should Marijuana Be a Medical Option?"
Reasoning:

“Over the past 15 years, it has become increasingly evident that cannabis use carries an increased risk for the development of psychosis. At the same time, medicinal cannabis (medical marijuana) has been legalized in many states, with minimal restrictions on prescribing indications…

Although cannabis may have some health benefits, it also has a variety of adverse effects, including psychosis, especially among those at high risk… This case underscores the importance of 1) aggressively managing cannabis use in patients at high risk for psychosis and those already suffering from psychosis, 2) apprising physicians who prescribe/recommend medicinal cannabis of its iatrogenic and psychototoxic liability among such individuals, 3) educating the public about the risk of cannabis-induced psychosis, and 4) the need for recent evidence about this public health risk to inform policy decisions about medicinal cannabis in the United States.”

Theoretical Expertise Ranking:
     Key Experts
Physicians [Physicians are the "key experts" in the medical marijuana debate because the issue is thought by many to be ultimately based on the medical value and risks of marijuana, and Physicians, with their training and clinical work, should (at least in theory) have the best knowledge of marijuana's medical value and risks.] [Note: Key Experts definition varies by sites that have this designation.]
