The National Institute of Health is conducting a marijuana study with the College of Medicine, according to University Communications. Test subjects will not be asked to change their marijuana consumption habits, as the goal of the study is to understand why people greatly reduce or completely stop smoking marijuana when they get older.  Psychiatry and psychology professor John Hughes is heading the experiment. “Many marijuana users stop smoking marijuana as they get older,” Hughes told University Communications. “We are trying to find out why they stop; for example, is it because they think marijuana makes them less productive, is it pressure from others, or fear of being caught?” Some students said they are extremely interested in learning the results of the study and offered their own insight. “First and foremost, life gets tougher and you have a lot more responsibility when you get older, especially if you do the family route,” sophomore Zach Sanford said. “It’s probably not too smart to be smoking weed a lot with all those people to be responsible for.” When asked what he thought the appeal of the drug is to young people, he said that friends’ influence was a major factor in their decision. “I think the feeling that it gives you is definitely part of the appeal and the social aspect of it too,” Sanford said. “Hanging out with friends and smoking weed is fun and social.”
