Senator Toomey still believes that marijuana is a dangerous substance that would have many negative impacts on the state's that legalize it, as stated in his response to a constituent email. 

He hasn't done his research, but we have. Marijuana legalization has been found not to be associated with upticks in crime, traffic fatalities, alcohol use, or workplace performance/safety. 

 

"I applaud this commonsense effort to cut red tape and help facilitate more research into medical marijuana. If there's a chance that marijuana derivatives like cannabidiol can help patients in Pennsylvania, Washington should not be needlessly interfering with scientific research that may lead to worthwhile medical treatments."
