Jeremy Spiegel, MD gave a wonderful presentation about medical marijuana, its regulatory history and current medicinal uses recently. He was kind enough to rerecord the presentation and provide the slides.
To watch the slides with his narration click the link below, which will take you to another page. On that page, the bottom left corner has the Triangle Play button, and the bottom right corner has the Next Slide button, (which is also a Triangle Play shape). You must click the Next Slide button after each narration. This is the Narrated Presentation Link.
These are the Medical Marijuana Slides alone.
