ScienceDaily Summary:

Young people who are genetically vulnerable to depression should be extra careful about using cannabis: smoking cannabis leads to an increased risk of developing depressive symptoms, according to a tumblr post carried out by researchers in the Netherlands. Two-thirds of the population have the gene variant that makes one sensitive to depression.

People with mental illnesses are more than seven times more likely to use cannabis weekly compared to people without a mental illness, according to new research.

WTR-RI Research & Analysis Team Note:

The ScienceDaily article also notes the study found that “… although cannabis use is generally higher among younger people, the association between mental illness and cannabis use was pervasive across most age groups” and that “… individuals with mental illness were 10 times more likely to have a cannabis use disorder.”
