The tobacco epidemic is one of the biggest public health threats the world has ever faced, killing more than 7 million people a year (WHO).
People with psychosis are more likely to smoke compared to the general population and it is believed that this could have a negative impact on cognitive functioning.
There is robust evidence that childhood adversity is associated with an increased risk of psychosis. There is, however, little research on intervening factors that might increase or decrease risk following childhood adversity.
Background: Previous literature suggests that prevalence of cannabis use in the early phase of psychosis is high, and that early psychosis patients are at high-risk for violent behavior. However, the link between cannabis use and violent behavior in early psychosis patients is unclear.
Background: The fact that Cannabis use can lead to psychotic symptoms has been recognized years ago. Moreover, when the patient is using cannabis, the distinction between a primary psychotic disorder and a cannabis-induced psychosis seems to be critical for the prognosis. However, few studies focused on the differences between these two diagnostic groups.
Association of Combined Patterns of Tobacco and Cannabis Use in Adolescence with Psychotic Experiences
Importance: There is concern about potentially causal effects of tobacco use on psychosis, but epidemiological studies have been less robust in attempts to minimize effects of confounding than studies of cannabis use have been.
Proportion of Patients in South London with First-Episode Psychosis Attributable to Use of High Potency Cannabis
The risk of individuals having adverse effects from drug use (eg. alcohol) generally depends on the frequency of use and potency of the drug used. We aimed to investigate how frequent use of skunk-like (high-potency) cannabis in south London affected the association between cannabis and psychotic disorders.
Cannabis is a known risk factor for schizophrenia, although the exact neurobiological process through which the effects on psychosis occur is not well-understood. In this review, we attempt to develop and discuss a possible pathway for the development of psychosis.
Background: Cannabis is the most widely used illegal drug in the world. Both an early cannabis use onset and the amount used contribute to the risk of suffering mental disorders in adulthood.
Objective: Review longitudinal studies conducted on adolescents associating early cannabis use with the subsequent occurrence of mental disorders.
