Medicinal cannabis study offers mixed findings on benefits

Medicinal cannabis is used for conditions such as spasticity associated with multiple sclerosis, intractable nausea and vomiting associated with chemotherapy, or severe treatment-resistant epilepsy.

A new study by Ireland’s Health Research Board (HRB) has found some evidence to support the use of prescribed medicinal cannabis for certain conditions.

But the agency found a general lack of quality in primary studies and reviews, which it said made it very difficult to draw “well-founded conclusions about the relative benefits (or lack thereof) of medicinal cannabis” for any given health condition.
