A recent study suggests that the use of tobacco and cannabis together may increase the risk of experiencing depression and anxiety.
The study examined a total of 53,843 adults who took part in online surveys. Among them, 4.9 per cent used tobacco, 6.9 per cent used cannabis exclusively, and 1.6 per cent used both substances.
The research, published in the open-access journal PLOS ONE, revealed that individuals who used both tobacco and cannabis reported higher rates of anxiety (26.5 per cent) and depression (28.3 per cent) compared to those who used either tobacco or cannabis alone.
Conversely, among individuals who abstained from both tobacco and cannabis, the percentages of anxiety and depression were notably lower at 10.6 per cent and 11.2 per cent, respectively.
The study’s results indicate that co-users of tobacco and cannabis were approximately 1.8 times more likely to experience these mental health disorders compared to non-users.
Nhung Nguyen, the study’s author from the University of California, San Francisco, commented, “The concurrent use of tobacco and cannabis is associated with a decline in mental well-being. This suggests that incorporating mental health support into tobacco and cannabis cessation programs could be beneficial in addressing this connection.”
