I have some experience with mental health in Australia and it is pretty dire honestly. There is a constant sense that the staff are concerned first with making sure you don’t hurt yourself because that would be a breach of their duty of care. This unfortunaty made much of the interaction between staff and patients adversarial.
I am currently entering the individual suppory industry and we have a concept called dignity of risk. You have to remember that people are entitled to take risks that they consider worthwhile regardless of what you think. This means if someone wants to smoke weed that is their choice, I can’t stop them. If they want to drink that is their choice and I have to respect that. This is because they are their own people and have their own autonomy.
