Dr. Jodi Gilman: Cannabis and Your Brain

Apr 15, 2025

In this episode, Therese Markow and Dr. Jodi Gilman discuss the implications of cannabis use on health and safety. Dr. Gilman explains that THC, the main psychoactive compound in cannabis, binds to cannabinoid receptors in the brain, affecting areas involved in emotion, memory, and decision-making. Cannabis use can lead to long-term brain alterations, particularly in adolescents, frequent users, and those using high-potency products. Dr. Gilman highlights the risks of cannabis-induced psychosis, depression, and anxiety, especially in those with a family history of psychosis. She also notes the lack of evidence for medical marijuana's efficacy and the challenges in detecting cannabis impairment.

 

 Key Takeaways:

  • Edibles typically last longer than smoked or vaped cannabis, but it takes longer to feel the effects. It can take 30-60 minutes to reach the brain.

  • The three things that make cannabis risky are the age you start to use cannabis, the frequency of use, and the potency of the product you are using. Those three factors increase the likelihood of long-term alterations on the brain, structurally and functionally.

  • Cannabis is a psychoactive substance, like alcohol, tobacco, nicotine, and cocaine; it is addictive to some people. It is estimated that 1 in 5 people who use cannabis will become addicted.

  • THC impairs attention, it impairs coordination, and it impairs reaction time - all of these are critical for driving. THC is thought to double the risk of a crash.

 

"People think cannabis is safe, like bubble gum. It’s not bubble gum. It's a psychoactive compound that affects your brain, and you really need to be cautious about these products." —  Dr. Jodi Gilman
