The relationship between cannabis and depression remains a topic of interest, although it is still poorly understood. While many report that cannabis helps them with their depression symptoms, some research suggests cannabis may in fact make depression worse. In a recent study of over 16 000 US adults, researchers found that individuals with depression had approximately double the odds of using depression than those without cannabis, with 216% higher odds of daily cannabis use. The association between daily cannabis use and depression was found to be strengthened from 2005 to 2016. Similarly, the overall prevalence of past-month cannabis use and daily cannabis use increased over the past 10 years, with rates increasing from 12.2% and 3.8% in 2005-2006 to 17.3% and 6.1% in 2015-2016.
