What's Known and Unknown about Marijuana (Part Two)
Marijuana legalization poses many challenges — especially those related to drug chemistry and toxicology — for researchers, law enforcement, and policy makers. In the latest episode of Justice Today, NIJ Communications Assistant Josh Mondoro hosts a conversation with NIJ Scientist Frances Scott about marijuana toxicology, including comparing its effects to alcohol, measuring impairment, and maintaining public safety as more and more states legalize recreational marijuana.

What's Known and Unknown about Marijuana (Part One)
Marijuana poses many challenges for researchers, law enforcement, and policy makers, challenges that fall into two fields: drug chemistry and toxicology. NIJ scientist Dr. Frances Scott joins this episode to explain the complications in drug chemistry and how difficulties defining marijuana lead to backlogs in crime labs around the country. NIJ Communications Assistant Josh Mondoro hosts.
