The study was conducted on two groups of 25 people each between the ages of 18 and 65 diagnosed with MS. While one group used marijuana, the other did not.

Both the groups were matched so there would not be significant differences due to age, gender, level of education, IQ before diagnosis, level of disability and duration of time with MS. On an average, the duration of marijuana use appeared 26 years.

“Given that about 40 to 60 percent of MS patients have problems with cognitive function to begin with, any drug that may add to this burden is cause for concern. This study provides empirical evidence that prolonged use of inhaled or ingested marijuana in MS patients is associated with poorer cognitive performance, and these effects have to be weighed against any possible benefit of using marijuana for medicinal purposes,” said study author Anthony Feinstein, MPhil, MD, PhD, with Sunnybrook Health Services Center and the University of Toronto in Ontario, Canada.

Scientists found that 72 percent of users smoked marijuana everyday and 24 percent were weekly users, while…
