Study Links Chronic Back Pain to Smoking


Study Links Chronic Back Pain to SmokingBack pain continues to be a common complaint nationwide, afflicting eight of every 10 Americans within their lifetimes. The American Chiropractic Association reports that this debilitating condition is the top sick day cause. Ranking second among doctor visit ailments, Americans spend over $50 billion per year to find reprieves from pain. A recent study discovered that smokers have a triple chance of developing relentless back pain, compared to subjects who abstained.

Smoking-Related Brain Activity Leads to Pain

Northwestern Medicine’s lead study author Bogdan Petre found that smoking affects the brain’s reaction to back pain. Subjects included 160 adults with subacute back pain that had lasted four to 12 weeks, 32 people who’d suffered from chronic pain for five or more years, and 35 pain-free controls. They underwent five MRI brain scans over a year. Each time the researchers examined these scans, subjects rated their back pain’s intensity and filled out questionnaires on their smoking habits and additional health issues.

Investigators evaluated activity in two brain regions that impact addictive behaviors and inspired learning. They learned that this particular circuitry is crucial for chronic pain development. These brain areas communicate with each other. A stronger connection between the two reduces chronic pain resistance. Petre concluded that corticostriatal circuitry raises the chances of back pain becoming chronic in smokers. The scientists determined that smoking makes people less resilient to pain episodes. By demonstrating how a learning segment of the brain permits tobacco dependence to converse with chronic pain, this study suggests that pain and addiction may have a relationship in general.

The circuit in question was active and strong in smokers’ brains, Petre noted. But a significant activity drop corresponded to a decreased vulnerability to ongoing pain among subjects who quit smoking voluntarily during this study. This evidence is the first to link chronic pain and smoking to the brain region that’s responsible for addictions and rewards. Treatments including anti-inflammatory medications helped participants control pain, but they didn’t alter their brain circuitry activity. So the scientists propose that behavioral interventions like smoking-cessation strategies could influence brain mechanisms to relieve chronic pain or reduce its risk.

Dr. Tae Shin, who wasn’t part of this study, reports that nicotine limits blood flow to discs cushioning your vertebrae while increasing your degenerative change rate. Smoking cigarettes also inhibits new bone growth and decreases calcium absorption, doubling your osteoporotic fracture risk, compared to non-smokers. Another study attributed about 14 million major diseases to smoking among Americans. These smoking-related illnesses cost $200 billion and kill around 6 million people worldwide annually.

Your Metabolism May Influence Quitting Aid Effectiveness

Many products are available to help the 42 million American grownup, young adult, and teenage smokers quit. Yet predicting which strategies may help most can be difficult. Almost 70 percent of smokers’ quitting attempts fail in the initial week. Previous studies have inspected the metabolism/smoking cessation aid relationship. But they didn’t test participant metabolisms before investigators made random treatment assignments. And they didn’t include Chantix (Varenicline), a prescription drug.

According to new research, your metabolism might help you select your most effective stop smoking medications. The new collaborative study involving four medical centers included 1,246 smokers seeking quitting remedies. To test their metabolisms, the researchers examined blood samples for the ratios between two nicotine-generating metabolites. These proportions reflect liver enzyme activity that helps metabolize nicotine. This information allowed the scientists to classify 584 people as normal metabolizers and 662 as slow metabolizers.

All participants also participated in behavioral therapy. The scientists assessed their smoking behaviors after the final week and during follow-ups at six months and one year.

Among normal metabolizers, the researchers found that almost 40 percent of Varenicline patients hadn’t relapsed, but 22 percent of patch subjects had. For slow metabolizers, these two treatments’ effectiveness was similar. But slow metabolizers experienced more Varenicline side effects. The authors concluded that slower metabolizers may receive more benefits from patches rather than pills. Quitting success decreased at the follow-ups, common occurrences in previous smoking cessation research, but ratios among both metabolizer groups using Varenicline and patches held.

These findings support using nicotine metabolite ratios as biomarkers to improve remedy choices while emphasizing that tobacco dependency is a heterogeneous issue and confirming that quitting smoking option effectiveness differs between patients. Doctors could use this helpful genetic biomarker clinically, notes Dr. Caryn Lerman, the lead author. Basing treatment decisions on nicotine metabolizing rates could guide smokers and physicians to choose medications that will improve their quitting rates.
