Despite irrefutable pharmacological evidence of the wide range in individuals' metabolism of opioid drugs, states continue to impose "one-size-fits-none" laws. For example, Massachusetts, apparently not entirely at peace with the abolition of the Salem witch trials, became the first state to establish a seven-day limit on first-time opioid prescriptions. Others followed. It's safe to say that no one is really paying attention to the science. So, here it is. Again.
