Driving under the influence of drugs (DUID) is a term used to designate the action of driving an automobile after the consumption of drugs or medications other than alcohol that interfere with the capacity to operate a vehicle safely. Unlike recreational drugs, prescription medications pose a unique challenge to those attempting to harness their benefits yet protect the driving public. As studies demonstrate a steady increase in opioid use and abuse in the United States, these same constituencies must regulate a significant percentage of drivers who are under the influence of opioids. ⋯ A sizable percentage of the driving public has detectable levels of opioids within their bodies. The best available evidence demonstrates psychomotor impairment following acute administration of opioids or an increase in opioid dosage, but impairment diminishes with chronic, stable opioid usage. Policy makers must account for this evidence when balancing the benefit of pain relief against the need for public roadway protection when drafting DUID legislation.

Practice Guideline
American Society of Interventional Pain Physicians (ASIPP) guidelines for responsible opioid prescribing in chronic non-cancer pain: Part I--evidence assessment.
Opioid abuse has continued to increase at an alarming rate since the 1990 s. As documented by different medical specialties, medical boards, advocacy groups, and the Drug Enforcement Administration, available evidence suggests a wide variance in chronic opioid therapy of 90 days or longer in chronic non-cancer pain. Part 1 describes evidence assessment. ⋯ The guidelines are based on the best available evidence and do not constitute inflexible treatment recommendations. Due to the changing body of evidence, this document is not intended to be a "standard of care."

Low back pain after either post lumbar surgery syndrome or spinal stenosis in the absence of surgery is a vexing problem. Post lumbar surgery syndrome can occur in any age group, while low back and radicular pain from spinal stenosis is a disease of aging. As the population ages, the incidence of symptomatic spinal stenosis will increase. There are currently limited treatment options for either group. Further surgery is not uniformly effective in relieving pain after previous surgery. While therapies are being developed to treat pain due to spinal stenosis, no therapy other than adhesiolysis will treat pain due to scarring. Adhesiolysis was developed as a means of removing epidural scarring leading directly or indirectly to compression, inflammation, swelling, or a decreased nutritional supply of nerve roots. Adhesiolysis utilizes a number of modalities in the effort to break up epidural scarring, including the use of a wire-bound catheter for mechanical adhesiolysis, placement of the catheter in the ventro-lateral aspect of the epidural space at the site of the exiting nerve root, and the use of high volumes of injectate, including local anesthetics and saline, either hypertonic or isotonic, along with steroids. ⋯ In summary, there is fair evidence that percutaneous adhesiolysis is effective in relieving low back and/or leg pain due to post lumbar surgery syndrome or spinal stenosis.

The personal and societal impact of chronic low back pain is considerable. The intervertebral disc is considered the etiologic source in up to 40% of patients, with considerable previous efforts directed at developing reliable and efficacious treatments. Recent publications, including a double-blind, randomized, placebo-controlled trial, using a one-time treatment of methylene blue, showed statistically significant, clinically relevant improvements in pain and function in the treatment groups. The postulated mechanism of action of methylene blue is denervation of small nociceptive fibers that grow into the annulus fibrosis, which are implicated in discogenic pain. ⋯ A case series.

Long-term opioid treatment has been used extensively in treatment of chronic low back pain (cLBP) in the last decades. However, there are serious limitations to the long-term efficacy of opioids and related side effects. ⋯ The current study demonstrated that chronic opioid intake may only reduce the temperature sensitivity but not pain sensitivity measured by QST which is a useful tool in detecting characteristic changes in pain perception of patients with chronic low back pain after long-term opioid intake.
