Meta-analysis finds a two-fold increased risk of developing schizophrenia and psychosis amongst those who smoke tobacco. Researchers speculate nicotine is most likely responsible for the link. They suggest future research looks at the link between e-cigarettes and a possible increased risk of psychosis in young adults, the largest consumer group for the products.
