Reven said she chose bergamot for the study because it is soothing to the central nervous system. Results include reduction in stress and anxiety, and an increase in feeling calm and relaxed.

Participants track the frequency of administering the inhalers and rate their comfort levels in daily logbooks.

Study participants, all in treatment for substance use disorder, report an increase of comfort and ease and a decrease in perception of stress after using the inhaler at least three times daily for one week. Reven said various studies on substance use disorder treatment indicate that when people no longer have the drugs in their systems in sufficient amounts, they experience a loss of pleasure and an increased sensitivity to stress and anxiety. "Those individuals have identified that relieving distress and increasing comfort during substance use recovery is vital to their success." "Those in treatment struggle to handle everyday living, overwhelming demands from work, family, the disease itself and even the treatment program," said Marian Reven, assistant professor in the WVU School of Nursing and a registered aromatherapist, who led the study. For the study, comfort was defined as the experience of relief, while ease was defined as calmness amid distress.

Researchers set out to determine whether the use of an aroma inhaler filled with bergamot essential oil produced an increase in comfort and ease, and a decrease in stress.
