Health-related costs per user are eight times higher for drinkers than they are for those who use cannabis, and are more than 40 times higher for tobacco smokers, according to a report published in the British Columbia Mental Health and Addictions Journal.
According to the report, “In terms of [health-related] costs per user: tobacco-related health costs are over $800 per user, alcohol-related health costs are much lower at $165 per user, and cannabis-related health costs are the lowest at $20 per user.”
