Dalhousie Substance Use and Addictions Lab is led by Dr. Sean P. Barrett in investigating tobacco, alcohol, polysubstance use, and other topics in the field of addictions research.

Dr. Barrett’s research aims to understand how various pharmacological & non-pharmacological factors contribute to different addictive behaviours, as well as determining the extent to which individual differences play a role in such factors.

Multiple research projects examining how one's smoking behavior, mood, and cigarette craving are affected by contextual cues and nicotine expectancies are currently being conducted in the Substance Use and Addictions Lab. Lab members closely collaborate with a variety of other researchers and institutions, in order to diversify and expand our understanding of cigarette addiction.

Dr. Sean Barrett is currently supervising a number of graduate students and undergraduate research projects. The laboratory is also currently recruiting volunteers who are given an opportunity to gain insight into research processes and work alongside current lab members.
