Is the relationship between use of high potency cannabis and mental health explained by frequency of cannabis use?

Globally, cannabis is the most commonly used internationally regulated drug. Policy is rapidly changing, and high-potency cannabis has proliferated in both legal and illegal markets. There is limited research into the mental health effects of high-potency in cannabis, and none conducted amongst general population samples. Additionally, it is unclear to what extent the relationship between high-potency cannabis and mental health outcomes is due to the potency of the drug, or associated increase in frequency of use. This talk reports findings from a large general population sample of UK adolescents, with contemporaneous measures of type of cannabis, cannabis use frequency, and validated mental health outcomes. Using these data, Lindsey characterises the relationship between use of high potency cannabis and mental health and explores the extent to which outcomes associated with use of high potency cannabis may be explained by frequency of cannabis use.
