E4 Bioscience helps cannabis investors and laboratory teams research, design, build, equip, license, operate, and market compliant cannabis laboratories. Whether acquiring, building, or retrofitting a cannabis laboratory, our team shares the expertise necessary to avoid delays, create sustainable revenue, and maintain compliance.

Blue Papers

We examine current and relevant topics in the cannabis laboratory space and write informative blue papers. What’s a blue paper, you ask? A blue paper is a white paper that is actually worth reading and provides much more than black text on white paper about a subject that only the author really cares about.

Blue Paper “Cannabis Laboratory Planning, Design, Licensing, Instrumentation, and Staffing”

Blue Paper “A Hemp Growers Guide to Compliance Testing for THC and CBD Levels”
