While national governments have to take action to stop drug abuse, appropriate pain relief is often hampered by lack of availability or barriers to accessibility of opioid analgesics. In many countries, poorly written laws and regulations restrict access to opioids analgesics and interfere with the medical availability of opioids for the relief of cancer pain. In many of these countries, logistics of these medications is so burdensome and complex that for physicians, nurses and pharmacists do not want to get involved.
