Effects Of The Raising The Minimum Legal Purchasing Age For Tobacco On Cigarette, Cocaine And Inhalant Consumption, Ahmed Adil

Theses and Dissertations

Over the past few years, several states have passed laws that increase the minimum legal purchasing age (MLPA) for tobacco from 18 to 21 years. This study examines the impact of statewide MLPA laws on youth tobacco consumption. Using data from the 2009-2019 Youth Risky Behavior Surveys (YRBS) and a difference-in-differences approach, I find that the enactment of MLPA laws is associated with a decrease in tobacco usage among adolescents. I also find that MLPA laws have important spillover effects to other youth risky behaviors. MLPA law adoption is associated with a reduction in cocaine use and inhalant abuse.

Investigating The Role Of Vasopressin Receptor 1a Expressing Neurons In Mouse Dorsal Raphe, Tirth Nimishbhai Patel

Theses and Dissertations

Human social interactions heavily impact our physical and mental wellbeing. Arginine-vasopressin (Avp) and serotonin have both been implicated in modulation of social behaviors ranging from affiliation to aggression. In male mice, Avp neurons in the bed nucleus of stria terminalis (BNST) show increased activity during prosocial behavior. BNST sends Avp afferents to the dorsal raphe (DR) in the midbrain, a home to a large portion of serotonin neurons in the mouse brain. Previous data suggests that DR is activated during male prosocial behavior with a female stimulus, and Avp indirectly excites serotonin neurons. We hypothesized that DR contains a population …
