(The White House) When the President took office, he directed all of his policymakers to develop policies based on science and research, not ideology or politics. So our concern about marijuana is based on what the science tells us about the drug’s effects.

According to scientists at the National Institutes of Health- the world’s largest source of drug abuse research - marijuana use is associated with addiction, respiratory disease, and cognitive impairment. We know from an array of treatment admission information and Federal data that marijuana use is a significant source for voluntary drug treatment admissions and visits to emergency rooms. Studies also reveal that marijuana potency has almost tripled over the past 20 years, raising serious concerns about what this means for public health – especially among young people who use the drug because research shows their brains continue to develop well into their 20’s. Simply put, it is not a benign drug.

Like many, we are interested in the potential marijuana may have in providing relief to individuals diagnosed with certain serious illnesses. That is why we ardently support ongoing research into determining what components of the marijuana plant can be used as medicine. To date, however, neither the FDA nor the Institute of Medicine have found smoked marijuana to meet the modern standard for safe or effective medicine for any condition.
