Raeford Brown, anesthesiologist and pediatrician at the University of Kentucky, says “We’ve known for some time that there’s a relationship between the exposure to opioids ... and people becoming addicted to opioids". No shit Sherlock! ;-P
"We should remember that opioids play an important role in helping patients manage acute and chronic pain alike", not to mention the important role they play in the massive profits earned every year by the pharmaceutical corporations that pump out this addictive, lethal demon-jizz. Oh and here's the punchline ...
"But while we wait for researchers to successfully develop non-addictive painkillers ..." people who make comments like this in articles on sites with the word "science" in the name should be pelted with rotten fruit for not mentioning the obvious solution; medical cannabis. Now legal in over 30 US states. Excellent for pain relief. Well known to be non-addictive, and certainly much less habit-forming or toxic than opioids or alcohol.
