C30. What about Weed? The Cannabis Controversy: Past, Present, and Future

C30. What about Weed? The Cannabis Controversy: Past, Present, and Future



Weed, pot, marijuana, cannabis. Whatever you call it, the United States has a long, complicated, and conflicted history with this controversial herb. Is it evil incarnate, or a panacea for all that ails us? In this lively presentation, we will discuss the many facets of cannabis, tetrahydrocannabinol (THC), hemp, and cannabidiol, including historical, legal, social, and clinical considerations, from local lore to changing statewide and national trends.

    Nicely done Stephen! Much of this knowledge is history but important. There has been and still is a wide diversity between use and not use. I liked your point that the science is very far behind. Do we have any active centers doing significant research?

    1. Stephen Strobbe

      Dear Dennis,
      Yes, I found the historical perspective to be intriguing, and telling. Research related to marijuana and THC remains problematic due, in no small part, to its continued classification as a Schedule I drug at the federal level. There are centers that are studying policy, or CBD, since regulations between psychoactive and non-psychoactive substances differ. Among others, these include, but are not limited to, affiliations with the University of California (UC) system.

    Fabulous historical perspective! I also liked your focus on physiological and psychological effects of cannabis use.
    Is there a way to get the slide with areas of the brain affected and the slide with systems of the body affected? I think these could be useful as handouts to our patients. (the credits were too small for me to read).
    Thanks for a great presentation.

      Dear Cheryl,
      Thank you for attending/accessing the presentation, and for your kind words. If you would like to contact me via email (, and put IntNSA Conference in the subject line, then I would be happy to provide these.

    This was the most informative and balanced presentation on cannabis I’ve heard in the past few years.
    thank you for continuing to inform and delight us.

    1. Stephen Strobbe

      Dear James,
      My pleasure, and thank you for attending/accessing the presentation!

  4. Addy Adwell

    Thank you for this presentation and especially the emphasis on systemic racism when it comes to marijuana policy.

    1. Stephen Strobbe

      Dear Addy,
      You are most welcome, and thank you! Yes, unfortunately, race has played a prominent role in laws, arrests, and imprisonment, across drug classes including, but not limited to, marijuana.

  5. Andrea Krasno

    Interesting presentation. Listening to the effects of “harmless” CBD was informative.

    1. Stephen Strobbe

      Dear Andrea,
      Thank you for attending/accessing the presentation. We still have so much to study, and learn!

  6. Rita Hanuschock

    Steve, this was excellent; thanks for your hard work and researching and putting the lecture together.
    A great educational lecture that everyone should watch.

    1. Stephen Strobbe

      Dear Rita,
      Thank you for attending/accessing the presentation, and your kind words. I found the process to be enlightening.

  7. Bari Platter

    Great presentation, Stephen! Nice to see the focus on cannabis and psychosis. It worries me that cannabis itself can induce a psychotic process that doesn’t resolve when the person stops using cannabis. More will be revealed…

  8. Rachel Shuster, BSN, RN, CARN, CAAP

    Thank you so much for this presentation, Dr. Strobbe. I appreciated this non-biased and detailed look at cannabis, including the history. As an individual who subscribes to harm reductionist philosophies, I really enjoyed this information. It’s helpful to know the real and perceived benefits and harms to best inform the individuals we care for, work with, and socialize with. This is one of my favorite IntNSA presentations thus far. Thanks again1

  9. Virginia Singer

    Thank you!
