Many people living with MS reach for everyday substances just like the rest of us. A morning coffee. A glass of wine to unwind. Perhaps a cigarette to take the edge off. But what does the science say about how these habits interact with multiple sclerosis symptoms? A newly published study offers some of the clearest answers yet. The findings are more nuanced than most people expect.

Every Benefit Comes With a Cost

Research published in the Archives of Physical Medicine and Rehabilitation followed 258 adults with MS over two weeks. Participants logged their use of four common substances: alcohol, caffeine, cannabis, and nicotine. They also reported their levels of pain, fatigue, stress, and depression four times each day.

A consistent pattern emerged. For nearly every substance offering some relief, a corresponding drawback came with it.

“Just as many people look to a cup of coffee for a pick-me-up, people with multiple sclerosis may seek caffeine to help with fatigue or alcohol to manage pain,” said Anna Kratz, professor of physical medicine and rehabilitation at the University of Michigan.

Caffeine and Multiple Sclerosis Symptoms: A Lift With a Sting

Caffeine produced the most straightforward trade-off. Participants who consumed it reported lower levels of fatigue. That is no small thing. Fatigue is one of the most debilitating challenges for those living with MS. However, that energy boost came with a noticeable rise in stress levels.

For someone already managing a complex neurological condition, elevated stress is not trivial. Stress can trigger symptom flares. It compounds the difficulties of daily life. Whether the short-term energy gain is worth that cost is a question worth sitting with.

Alcohol: Calmer, But More Exhausted

Alcohol appeared to reduce stress. That may explain why some people with MS use it as an informal coping tool. Pain and stress are persistent companions with this condition. The appeal of something that reliably blunts both is understandable.

Yet the data on MS symptoms and substance use tells a more complicated story. Alcohol was also associated with increased fatigue. Around 80 per cent of people with MS report fatigue as a significant symptom. Anything that worsens it deserves a second look.

Cannabis: Pain Relief, But at a Cost

Cannabis showed the clearest benefit for pain management. For people with MS who live with chronic pain, that matters. But cannabis use was also linked to increased fatigue. That is the same double-edged pattern seen with alcohol.

When fatigue is already a hallmark of multiple sclerosis symptoms, anything that amplifies it needs careful consideration. That conversation is best had with a doctor rather than managed alone.

Nicotine and MS Symptoms: No Upside Found

Of all four substances, nicotine was the only one with nothing to offer. It increased fatigue without reducing pain, stress, or depression. Existing research also suggests that smoking may worsen MS progression over time. The case against it is straightforward.

What This Means for People Living With MS

Professor Kratz is clear about the purpose of research like this. It is not to judge. It is to inform. “Insights from studies like this could prompt a person with multiple sclerosis to reflect on what they are putting into their bodies and how it is impacting their symptoms,” she said.

Understanding MS symptoms and substance use gives clinicians a better basis for real conversations with patients. “Being able to understand the role these substances play will allow providers to better advise their patients,” Kratz added.

These substances may feel routine. Some even feel harmless. But they can have real effects on a condition as complex as MS. None of them fit neatly into a “safe” or “harmful” box. Each carries trade-offs.

If you are living with MS and regularly using any of these, it is worth talking to your GP or neurologist. That conversation may be more useful than you expect.
