Assisted suicide means that someone provides the means and/or information for another person to commit suicide. When a physician is involved, the practice is physician-assisted suicide.
In Oregon, physician-assisted suicide was legalized in 1997 via a ballot measure. In Washington State, a similar law was passed via another ballot measure in 2008 and went into effect in 2009. No such law has made it through the scrutiny of a legislature despite more than 100 attempts.
The Washington and Oregon laws are a recipe for elder abuse. The most obvious reason is due to a lack of oversight when the lethal dose is administered. For example, there are no witnesses required at the death; the death is allowed occur in private. With this situation, the opportunity is created for an heir, or some other person who will benefit from the patient’s death, to administer the lethal dose to the patient without his consent. Even if he struggled, who would know?
Oregon's suicide rate, which excludes suicides under its physician-assisted suicide law, has been "increasing significantly" since 2000.
