Imagine a world where psychiatric medication works 100% of the time, relieves 100% of symptoms, and causes no side effects. In this world, we all agree on the precise differences between mental illness and personality. It’s easy to tell the difference between someone who tires easily and someone who has the flu, right? Why should mental illness be any different? Imagine that drugs work perfectly, and they don’t alter who the “real” person is. In the world I’m describing, there are no rational reasons to refuse treatment - unlike in this one. Do people with mental illnesses still have a right to refuse pills, or inpatient commitment, or whatever we find works well?
In the real world, this world that we live in, there are no absolute cures for mental illness. Up until pretty recently, scientists considered brutal procedures like the lobotomy acceptable treatments for mental illness. Today the lobotomy has been replaced by drugs that can cause permanent facial ticks and neurological symptoms, drugs that cause massive weight gain, diabetes, and heart disease. Electroconvulsive therapy, which can cause permanent memory loss, is coming back into fashion. In addition to whatever personal objections they might muster to treatment, often patients only have the option of treatments that stand to cause them significant, lasting harm.
This confuses the issue of the right to refuse treatment. It makes perfect sense to refuse a treatment that could destroy your memory, right? It seems reasonable that people might rather hallucinate than have a heart attack. Unfortunately, this leads us to focus on medication only as a heath decision, weighting the health benefits versus the health costs. Given that side effects generally don’t show up in the medical community’s consciousness, this leads doctors to feel safe in trying to force newer medications on their patient. But, more than that, it ignores the fact that these kind of decisions ought not to be based on a simple balancing of the possible heath benefits and risks. The right to refuse treatment is a human right, the right to sovereignty over one’s own mind. We cannot deny people their rights simply because we think we know what would benefit them.
It doesn’t matter, then, how close to the ideal our world may be. We don’t abstain from medicating people against their wills because we think that they understand the risks and benefits better than their doctors. While occasionally, as compassionate human beings, it may be necessary to stop the sickest among us from destroying themselves, for the most part we cannot ethically interfere with the way people chose to live their lives and deal with their illnesses. The law allows people to make their own choices about what they do to their bodies and minds because we respect their autonomy as human beings.
