Alcohol is a legal drug. Fentanyl is an illegal drug. Yeah, the individual is responsible for dealing with a substance dependence issue - harder to get clean if the drug you are addicted to is legal and readily available.I don't think the province is legally or morally responsible for someone who didn't deal appropriately with a substance dependence issue in a timely, effective fashion.
The province kept the LCBO open during the pandemic. Is the LCBO an essential business? No - but there are enough people in Ontario physically dependent on alcohol that if they all went into withdrawal and ended up in the Hospital, the system couldn't handle the strain while dealing with all the COVID patients.
Someone who is physically addicted to alcohol cannot stop "cold turkey", as the result could be death.
