Cornyn, Feinstein to Hold Hearing on Public Health Effects of Marijuana

WASHINGTON — Tomorrow U.S. Senators John Cornyn (R-TX), Chairman, and Dianne Feinstein (D-CA), co-Chairman, will hold a hearing of the Senate Caucus on International Narcotics Control to examine public health questions and issues surrounding marijuana, the most commonly used illicit drug in the United States, as more states legalize it for the treatment of medical conditions and recreational use.

This hearing will provide an opportunity to understand what scientific research has yielded as it relates to marijuana’s efficacy as a medical treatment, its effect on motor skills and driving, and its impact on adolescent development, cognition, and mental illness, along with what questions still need to be answered.
