Presentations on Society:

Cannabis University
With Robert Solomon

7:30 p.m.  |  Osher Gallery 1, Kanbar Forum

Since 1969, cannabis has been federally classified as a Schedule 1 drug under the Controlled Substances Act, labeling it as having no currently accepted medical use and a high potential for abuse despite  While cultural and medical norms and state laws have shifted, this federal law remains in place, preventing research and the inter-state transportation of cannabis and limiting cannabis banking. Join University of California, Irvine law professor Bob Solomon to learn more about these laws and the issues arising from state medical and recreational marijuana laws.

Legalized For Whom?
With Eugene Hillsman and Rodney Holcomb

8:30 p.m.  |  Osher Gallery 1, Kanbar Forum

The legalization of recreational cannabis use in California has been complex from legal, cultural, and economic standpoints. Begin untangling these knotty issues with Rodney Holcombe, staff attorney at the Drug Policy Alliance, and Eugene Hillsman, acting director of San Francisco’s Office of Cannabis come hear about some of the ways California has changed since legalization and get a better understanding of what the future may look like for cannabis culture and the law.

Terpenes Explained
With Dr. Philipp Zerbe

9:00 p.m.  |  Fisher Bay Observatory Gallery 6

Plants are nature's master chemists they produce a staggering diversity of small molecule metabolites to survive, thrive, and communicate in constantly changing environments for lifespans of up to several hundred years. Among these metabolites, terpenoids form the largest group, with essential functions in plant development, ecological adaptation, and fitness. Many terpenoids are also valued as therapeutics, food additives, fragrances, biofuels, and more. Learn about these essential substances from UC Davis professor Philipp Zerbe, whose research group seeks to decode plant-specialized metabolism and translate it into innovative biotechnology applications.
