Personal profile


Dr Lucy Troup’s research focus is centered round the effects of Cannabis use on brain function. The approach taken in my research involves imaging the brain with EEG specifically Event Related Potentials.  Recent research has an emphasis on the effects of cannabis on emotion processing from a number of perspectives, including clinical neuroscience, social neuroscience, and more traditional cognitive neuroscience. I have extensive relationships with the use of cannabis in Colorado, both from an academic research perspective and from her relationships in the state with the cannabis industry, since state legalization for recreational use. Her research focuses exclusively on how cannabis use effects brain and behavior. She has advised the local school district and emphasizes the importance of developing fact based scientific support for arguments for and against cannabis exposure.
