Mark Brennaman

Oklahoma Cannabis Academy

Mark Brennaman has been a cannabis activist since 1977 when he began working for Kentucky Marijuana Feasibility Study. Mark conducted a lot of hemp research that resulted in uncovering the government’s effort to hide all information about hemp and cannabis.

He recently retired from teaching student success courses at University of Central Oklahoma, and is also a certified laughter yoga leader.

Mark will display hemp plastics, paper, seed oil, and historical documents and photos and will speak about the Homecoming of Cannabis and Hemp in America.
