Neural Hyperactivity During Value-Based Decision-Making In People With Daily/Near Daily Cannabis Use, Miranda Ramirez
Neural Hyperactivity During Value-Based Decision-Making In People With Daily/Near Daily Cannabis Use, Miranda Ramirez
Theses and Dissertations--Psychology
Value-based decision-making involves the coordinated effort of multiple brain regions to guide future choices based on past experiences. These processes are disrupted in cannabis use disorder, where individuals continue to use cannabis despite negative consequences. Reinforcement learning (RL) paradigms can be used to capture changes in the value of available options and may inform how the brain is impacted by frequent cannabis use. This study combined fMRI with behavioral modeling of probabilistic choice task data to compare value-based choices between young adults reporting daily/near daily cannabis use (CAN) and controls (CTRL). Participants selected one of two options reinforced ($0.25) at …
The Influence Of Flavor On The Abuse Liability Of A Heated Tobacco Product And Its Feasibility As A Menthol Cigarette Substitute, Augustus White
The Influence Of Flavor On The Abuse Liability Of A Heated Tobacco Product And Its Feasibility As A Menthol Cigarette Substitute, Augustus White
Theses and Dissertations
Heated Tobacco Products (HTPs) purport to expose people that use cigarettes to fewer of the harmful or potentially harmful constituents of tobacco while still delivering reinforcing amounts of nicotine (Auer, Concha-Lozano et al., 2017). An exemplar of the HTP class, IQOS, and its three varieties of “HeatSticks” have been authorized by the Food and Drug Administration (FDA) as “Modified Risk Tobacco Products” (MRTP). However, as the FDA is planning to ban menthol as a characterizing flavor in cigarettes, questions remain regarding whether characterizing flavors should be permitted in HTPs (FDA, 2022e). New evidence regarding HTP abuse liability (i.e., the likelihood …
