“…Further, several studies (20, 21) suggest a bidirectional relationship, as cannabis use variables do not solely explain the psychiatric outcomes observed nor do pre-existing psychiatric conditions fully explain the increased use of cannabis. Some researchers (22) have suggested that individuals with high levels of anxiety sensitivity or hopelessness may be more sensitive to the negative reinforcement processes of substance use (i.e., the ability of substances to modulate negative affective states) than non-affected individuals; however, some individuals experiencing the onset of mania or depression are not more likely to report increased cannabis use than those not experiencing these disorders (23, 24). In addition, other authors (25) have questioned the hypothesis that individuals may use cannabis to self-medicate psychotic or depressive symptoms.…”

“…The association between depression and cannabis use is long known there is a higher risk for the male gender; this observation is also shown in this study. Besides depression, other psychotic diseases such as anxiety, bipolar disorder, and schizophrenia show association with cannabis use 31 . Along with this, a study suggests that individuals with higher genetic predisposition for schizophrenia are as much more likely to use cannabis as and in more quantity than those with no genetic predisposition.…”

“… 13 The model also includes protective elements: if the subject is well-nourished, the absence of minimally sufficient conditions may prevent the outcome (i.e., tuberculosis), prolong the latency period, or diminish the severity of illness. 7 Additionally, several psychiatric illnesses are compatible with the INUS model, such as schizophrenia 14 and bipolar disorder 15 in the presence of cannabis use; and depression and post-traumatic stress disorder after domestic violence. 16 …”
