Smoking and drinking alcohol to excess are unhealthy habits.
- Smoking can increase your risk of developing multiple sclerosis, and may make your MS worse if you continue to smoke.
- Alcohol is a powerful drug. If abused, it produces multiple effects on the central nervous system and other organs of the body.
The Office of the U.S. Surgeon General has established that smoking causes serious health problems; subsequent studies by many other groups have confirmed this.
- Smokers are generally recognized to have higher rates of lung cancer, heart disease, emphysema and other respiratory problems, and lower birth weight infants than nonsmokers.
- Smoking is known to produce shortness of breath, susceptibility to lung infections, and heartbeat irregularities, which might transform a mild or moderate neurological limitation in a person with MS into a severe disability.
- Furthermore, smoking presents a significant fire hazard when the smoker suffers from weakness or incoordination.
Help to quit

In addition to general health and safety concerns, smoking increases a person's risk of developing MS and of disability progression.
- A new summary paper outlines the considerable evidence that smoking is a risk factor in the development and progression of MS.
- A 2005 paper in the journal, Brain, supported the link between smoking and the risk of developing MS, and suggested that smoking may be a risk factor for transforming a relapsing-remitting clinical course into a secondary-progressive course.
- Researchers recently reported links between smoking and brain tissue damage observed on MRI (magnetic resonance imaging) scans of 368 people with MS.
- In a study comparing 1465 smokers, ex-smokers and never-smokers, all of whom had multiple sclerosis, MS disability progressed more quickly in smokers, and this difference was also noted in MRI measures of disease activity. For several measures, ex-smokers did not differ substantially from never-smokers, suggesting that quitting may delay MS progression.
- In a study of nearly 700 people whose medical records were reviewed by researchers in Sweden, current smokers were significantly more likely to develop antibodies associated with immunity to interferon beta treatment for MS than non-smokers.
- The Ausimmune Study, partly funded by the Society, was undertaken to investigate whether increased exposure to sunlight and vitamin D may be protective against MS in people who had not yet been diagnosed with MS, but who had experienced a first neurologic episode that often leads to MS (CIS -clinically isolated syndrome); in a follow-up study, they found that the risk of developing a CIS increased by 79% in people who had ever smoked.
Alcohol affects the central nervous system and can interfere with medications
Acute alcohol intoxication can cause loss of balance, uncoordinated movements, slurred speech, and impaired judgment and thinking. Chronic alcohol abuse commonly results in numbness, tingling and loss of sensation, tremor, lack of coordination, dementia, and may damage the liver, stomach and other organs.
Some people with MS report that some of their neurologic symptoms, especially imbalance and lack of coordination, temporarily worsen after even one drink. Since alcohol depresses the central nervous system, it may also have an additive effect with certain medications that are commonly prescribed for MS. These include baclofen, diazepam, clonazepam and some antidepressants.
Talk to your physician about how much alcohol is appropriate for you to drink and how often.
