Originally published July 1, 2015Last month, I talked  about hepatitis C and pain,  and presented information about over-the-counter  and prescription pain  medication. Nonsteroidal anti-inflammatory drugs (NSAIDS)  and opioids  are effective painkillers, but they are associated with the risk of   medical complications. This month I focus on pain management techniques  that  have little or no risk of injuring the liver or other organs in  the body. I  start with the controversial one—marijuana.  
Cannabis
                    Marijuana (Cannabis sativa) is slowly emerging from   its status as the cause of “reefer madness” to a more reputable one  showing  potential medical benefits. However, before running out and  buying some weed  and a bag of Cheese Doodles, let’s explore these  questions:
First, let’s get one  big  frustrating fact out of the way: Marijuana is classified as a Schedule 1   drug. Drugs with a schedule 1 designation are deemed as having a high  potential  for abuse and no accepted medical use. Marijuana is tucked in  there along with  heroin, LSD, peyote, and ecstasy. Politicians  determined this, not scientists.  Because of this classification,  marijuana is nearly impossible to obtain and  test in clinical research.  The bureaucracy is enormous, and permission is hard  to get. In 2010, Time magazine summed it up this way, “Pot is listed as  Schedule 1 because  science hasn’t found an accepted medical use for it, but  science can’t  find a medical use for it because it is listed as Schedule 1.”
It is hard to imagine  that marijuana is classified  as a Schedule 1 drug when there has never been a  reported death from  marijuana overdose. Compare this to annual deaths from  acetaminophen  (300) or nonsteroidal anti-inflammatory drugs (7,000-10,000), and   opioids (16,000). Compare marijuana’s zero deaths to those from legally   obtainable substances, such as alcohol (88,000) or tobacco (480,000  including  second-hand), and cannabis seems much safer.
This is not to say  that  marijuana isn’t without risk. In Colorado, two cannabis-related deaths  are  under investigation; one a suicide, the other a homicide in which  other  substances were involved. Also disturbing is the fact that the  number of auto  accidents have risen in Colorado since the legalization  of pot. 
These few deaths are  hardly  worth condemning pot for, especially since marijuana use may be causing   a drop in the number of deaths from prescription opioids. States with  liberal  marijuana laws had a 25 percent reduction in opioid deaths.  Cannabis is also  associated with lower death rates in patients with  traumatic injuries. That is  just the beginning. The potential benefits  are so many, that U.S. Surgeon  General, Vivek Murthy said, “We have  some preliminary data showing that for  certain medical conditions and  symptoms, marijuana can be helpful.”
Is marijuana effective  for pain? Yes! I could write  pages on this. The bottom line is that  cannabinoids (a chemical  compound found in a number of plants, including  Cannabis sativa)  interact with specific receptors in the brain. This appears to  reduce  pain and inflammation. 
Will marijuana cause  liver  injury? It’s not well researched, but probably not. A Canadian study of   690 participants led by Laurence Brune and colleagues found, “Marijuana  smoking  does not accelerate progression of liver disease in  HIV–Hepatitis C  coinfection.” (
Clinical Infectious Disease, Sep 2013). Previous studies have had mixed results.
What is marijuana’s  effect on  hepatitis C? The studies have been mixed. There is some research   suggesting that marijuana may lower immune response. However, cannabis  is being  used in cancer studies with favorable results. In short, we  don’t know.
What are the downsides  of  marijuana use? There are quite a few, such as risks of addiction,  cognitive  impairment, increased bleeding risks, etc. Frankly, we don’t  know all the risks  since marijuana has not been rigorously researched. I  suspect that a day will  come when marijuana will come with a paper  insert that will list all the  potential drug interactions, side  effects, and warnings. Until then, keep this  in mind:  We don’t know if  cannabis  interacts with hepatitis C medications. Marijuana may  interfere with drugs that  are metabolized via the liver’s cytochrome  P450 enzyme system. This may affect  the dose of your hepatitis C  medications. If you use marijuana, work with a  doctor who will  prescribe it, and show you how to use it medically and  responsibly. 
  
Note: If you  are on or are being considered for liver  transplantation, marijuana use  can be a disqualifier. The state of California  recently introduced  legislation to prohibit marijuana use as a factor for  disqualification  for organ transplantation. Other states may follow suit,  especially in  the light of Congress’s latest legislation banning federal  interference  on state medical marijuana laws. 
 Some insurance  companies and  state Medicaid programs are requiring drug testing prior to  approval of  hepatitis C treatment. If your medical provider has prescribed   treatment and you use pot, find out if there will be drug testing. If  so,  educate yourself about the washout period, or how to pass the test;  it varies  depending on how often you use marijuana. 
Drug-Free Pain Control
                  Ideally, relieving  pain without drugs is the safest  approach. The trick is to work with a  specialist who is trained in the  art of introducing drug-free pain measures  while slowly reducing pain  medication. All sorts of drug-free techniques are  used, such as  acupuncture, massage, hypnosis. Below are three drug-free  techniques  worth considering.
  
1. Exercise: I  was surprised to learn that exercise topped the list of ways to reduce   chronic pain, particularly arthritic and inflammatory pain. Exercise  also helps  fibromyalgia, migraine headaches and back pain. Aerobic  exercise seems to be  the best, and the intensity is determined by what  you can tolerate. Walking is  great exercise because it doesn’t require  anything more than a good pair of  shoes, sunscreen, and a safe place to  walk. Gardening, dancing, bicycling,  swimming, yoga, and tai chi are  other fun ways to stay fit. If you are new to  exercise, be sure to talk  to your medical provider before starting. Start slow  and only do what  feels comfortable. 
2. Meditation: There   are countless studies documenting meditation’s profound effect on  reducing  pain. Personally, I couldn’t imagine sitting still while  relaxed, let alone in  pain, so I had to experiment with this one  myself. It works. It wasn’t as good  as a spinal block or sedation, but  it was free and without risk. There are many  ways to meditate, but  probably the most well-known in the U.S. is  mindfulness-based stress  reduction (MBSR) developed by Jon Kabat-Zinn. MBSR is  taught in  hospitals, clinics, and communities. 
3. Quitting  Smoking:   In “Prevalence  and risk factors for patient-reported joint pain among  patients with  HIV/Hepatitis C coinfection, Hepatitis C monoinfection,  and HIV monoinfection,”  Alexis Ogdie and colleagues reported that  hepatitis C patients who smoked, had  higher levels of joint pain. (
BMC Musculoskeletal Disorders 2015) 
(See review  of this article by Alan Franciscus here.) Granted, the study did not show that tobacco cessation would reduce  pain, but  we all know that smoking presents huge health risks. If you  do decide to quit,  seek professional help. Perhaps MBSR and exercise  will help. 
 
Final Words
                                      I have tried to simplify a  very complicated subject.  Pain management deserves more than I gave it  here. In nursing, I learned that  pain is the fifth vital sign. In  short, pain should be taken seriously.  However, the tragic reality is  that pain is understudied and poorly  misunderstood. Some physicians  over-prescribe painkillers; some under-prescribe  them. The bottom line  is that if your pain is not well controlled, ask to see a  pain  specialist.
