As marijuana legalization expands in the United States, concerns about potential health risks are growing. While most users have no problems, a growing number, particularly heavy users, report addiction, psychosis and other negative consequences.
Dr. Kevin Gray, a psychiatrist specializing in bio-behavioral medicine, highlights the complex nature of cannabis: “Cannabis has both therapeutic and potentially problematic effects.”
The New York Times interviewed hundreds of people experiencing serious and sometimes frightening symptoms related to cannabis use.
One story tells of actor David Krumholtz, who after resuming marijuana use, developed cannabinoid hyperemesis syndrome (CHS). This debilitating condition causes cycles of intense nausea and vomiting, leading to dehydration, seizures, and even death in rare cases. Krumholtz lost 100 pounds and attended the emergency room.
These stories highlight the importance of public awareness of the potential downsides of marijuana use, particularly for frequent users.
