A study by the Canadian Centre for Addiction and Mental Health (CAMH) has found that alcohol leads to the most destruction in Canada, compared to other substances. The study was conducted using multi-criteria decision analysis (MCDA), a comprehensive research method that allows multiple objectives to be considered. The analysis compared the physical, mental and social harms caused by drugs, loss of life, declining physical health, economic cost, and environmental damage to each substance. Each substance was given a score from 0-100 relating to 16 types of possible harm, with alcohol scoring 79/100 and nicotine scoring 45/100. The findings highlighted a significant gap between the harms linked to alcohol and the current regulatory system in Canada.
