Background Longitudinal studies reporting the association between cannabis use and developing depression provide mixed results. The objective of this study was to establish the extent to which different patterns of use of cannabis are associated with the development of depression using meta-analysis of longitudinal studies. Method Peer-reviewed publications reporting the risk of developing depression in cannabis users were located using searches of EMBASE, Medline, PsychINFO and ISI Web of… Expand

TLDR
The findings indicate that cannabis use is no more than a minor risk factor for the development of elevated anxiety symptoms in the general population, and may inform the debate surrounding the legalisation of cannabis. Expand

TLDR

Expand
Cannabis use and the course and outcome of major depressive disorder: A population based longitudinal study

The association between cannabis use and anxiety disorders: Results from a population-based representative sample
TLDR
The findings suggest that cannabis use and CUDs are not associated with increased incidence of most anxiety disorders and inversely, most anxiety Disorders are notassociated with increased occurrence of cannabis use or CUDS. Expand
Cannabis Use and the Risk for Psychosis and Affective Disorders
TLDR
The evidence that heavy use of high-THC/low-CBD types of cannabis increases the risk of psychosis is sufficiently strong to merit public health education and the possibility that CBD may be therapeutically useful. Expand

TLDR
Evidence of high prevalence and a 3-fold comorbid association between CUD with MD and Cud with GAD is confirmed, which confirms the evidence of evidence-based policy interventions with effective, integrated management ofComorbid CUDs with psychiatric disorders may contribute to positive patient outcomes. Expand
The association between cannabis use and suicidality among men and women: A population-based longitudinal study.
TLDR
The findings support a longitudinal association between heavy cannabis use and the incidence of suicidality in men, but not in women and merit further research into the unique effects of sex differences on cannabis induced psychopathology. Expand

Exploring the association between cannabis use and depression.
TLDR
Heavy cannabis use and depression are associated and evidence from longitudinal studies suggests that heavy cannabis use may increase depressive symptoms among some users, but it is still too early, however, to rule out the hypothesis that the association is due to common social, family and contextual factors that increase risks of both heavy cannabis Use and depression.

Cannabis use and depression: a longitudinal study of a national cohort of Swedish conscripts
TLDR
Only subjects with the highest level of cannabis use had an increased crude hazard ratio for depression, and the finding of an increased risk of schizoaffective disorder is consistent with previous findings on the relation between cannabis use and psychosis. Expand
Cannabis and depression: an integrative data analysis of four Australasian cohorts.
TLDR
More frequent cannabis use was associated with modest increases in rates of depressive symptoms and this association was stronger in adolescence and declined thereafter, suggesting that the association was strongest in adolescence. Expand
Cannabis use and risk of psychotic or affective mental health outcomes: a systematic review
TLDR
There is now sufficient evidence to warn young people that using cannabis could increase their risk of developing a psychotic illness later in life, although evidence for affective outcomes is less strong. Expand
Cannabis use and psychosocial adjustment in adolescence and young adulthood.
TLDR
Cannabis use, and particularly regular or heavy use, was associated with increased rates of a range of adjustment problems in adolescence/ young adulthood-other illicit drug use, crime, depression and suicidal behaviours-with these adverse effects being most evident for school-aged regular users.

TLDR
In participants with no baseline depressive symptoms, those with a diagnosis of cannabis abuse at baseline were four times more likely than those with no cannabis abuse diagnosis to have depressive symptoms at the follow-up assessment, after adjusting for age, gender, antisocial symptoms, and other baseline covariates. Expand
Does cannabis use predict the first incidence of mood and anxiety disorders in the adult population?
TLDR
The associations between cannabis use and the first incidence of depression and bipolar disorder, which remained significant after adjustment for strong confounders, warrant research into the underlying mechanisms. Expand

TLDR
After adjusting for differences in baseline risk factors of marijuana use and depression, past-year marijuana use does not significantly predict later development of depression. Expand
The relationship between cannabis use and DSM-IV cannabis abuse and dependence: results from the National Longitudinal Alcohol Epidemiologic Survey.
TLDR
The risk of cannabis abuse and dependence was found to increase with the frequency of smoking occasions and slightly decreased with age, and more severe comorbidity was associated with dependence compared to abuse, suggesting that cannabis might be used to self-medicate major depression. Expand
A longitudinal study of cannabis use and mental health from adolescence to early adulthood.
TLDR
The findings suggest that the primary causal direction leads from mental disorder to cannabis use among adolescents and the reverse in early adulthood. Expand
