Arizona psychiatrist and researcher Dr. Sue Sisley is conducting a controversial marijuana study that could have implications across the nation.

Sisley has faced plenty of hurdles in her study, which explores the effects of four marijuana strains on military veterans who suffer from posttraumatic stress disorder.

Though she was terminated from the University of Arizona College of Medicine, Sisley has since gotten her research approved by the government and secured funding. She believes that we owe it to veterans to put pot through a controlled trial, which will help people to understand whether or not the claims that it helps PTSD are accurate.

Sisley is currently looking for a location to complete the rest of her research. She has stated that as soon as they find a location in Scottsdale or Phoenix, they will be ready to ask the DEA to inspect it. If successful, they will be able to get a Schedule I research license, which will allow them to proceed with buying the drug from the government.

Sisley has said that that as veterans continue to use weed to treat PTSD, it is now more important than ever to find out which strains most benefit those who suffer from the disorder.

The research will take around two years to complete and Sisley has stated that she will need 38 veterans to participate in the study in order to get accurate results.
