• 200 participants from Rhode Island tested the effects of medical cannabis inhaling.
  • The main reason for its use is chronic pain.


There is little understanding of the relationship with medical marijuana users. We tried to characterize the socio-democratic aspects and reasons for the use of medical marijuana in Rhode Island, and participants (n = 200) were recruited from one of the two pain treatment centers in Rhode Island and were asked to take a short survey that included the assessment of pain interference by Short Pain Inventory (BPI).

Most participants were male (73%), Caucasian (80%), university educated (68%) and insured (89%). The most common reason for using medical marijuana was to find that it was chonic pain.

Study results

participants were more likely to have BPI inference pain scores> 5 if they were older (OR: 1.36, 95% CI: 1.04-1.78) or reported cannabis use as a replacement for prescription drugs (OR: 2) , 47, 95% CI: 1.23-4.95) and were less likely to have a score> 5 if they had higher yields (OR: 0.53, 95% CI: 0.40-0.70) or they said they were sometimes treated for alcohol addiction. One fifth of the participants had a history of drug or alcohol abuse.

Most participants report that medical cannabis improves their symptoms of pain and are interested in alternative treatment options for opioid therapies
