Q: I am 59 years old and have suffered from chronic pain since an auto accident about 10 years ago. A relative told me that smoking marijuana or eating products containing tetrahydrocannabinoid (THC) or cannabidiol (CBD) could really help me get around better with a lot less discomfort.

However, I’ve been reluctant because of various reports that it can lead to use of more powerful pain killers and possible addiction. My doctor said she could provide me with a letter certifying that I need THC/CBD for medical reasons. Are there any studies on this topic that would help me make a decision about this?

A: A study published about three years ago in the reputable British Medical Journal (BMJ) appears to provide the best information.

Chronic pain is defined as pain persisting or recurring for three months or more and affects approximately one in five people. It is more common in women, older persons, veterans, Indigenous peoples (such as Native Americans, Alaskan Natives and Aboriginal Canadians) and those who are socioeconomically disadvantaged.

The key points of the BMJ study are: 1. Non-inhaled medical cannabis/ cannabinoids (MCC) can slightly improve pain and physical functioning for people living with chronic cancer or non-cancer pain; 2. Non-inhaled MCC may lead to a small improvement in sleep quality; 3. MCC commonly cause transient dizziness and, less frequently, cognitive impairment, nausea, vomiting, drowsiness and impaired attention.

It is always important to discuss use of MCC with your physician, as there are a number of prescription medications you may be taking that might interact adversely with MCC. You are fortunate to have a physician who seems open to such a discussion.

As such, a one-week trial of consistent use seems a worthwhile undertaking, scheduled during a time when you can stay home and avoid activities that might be dangerous. Should you have any of the above-noted adverse effects, this approach is more rewarding if you can maintain phone contact with your physician every two to three days in the first week or so, to deal with any questions or concerns you or she might have during this trial.
