Can marijuana be beneficial to your health? Most American adults — 81 percent — think so, according to new national survey results published online by Annals of Internal Medicine. The survey included responses from 9,003 adults considered a nationally representative sample. The believed benefits cited by the most people were managing pain (noted by 66 percent of participants), treating diseases such as multiple sclerosis and epilepsy (48 percent), and easing stress, anxiety and depression (47 percent). That said, 91 percent of respondents said they also believe that marijuana comes with risk, the most common being legal problems (cited by 52 percent), addiction (50 percent) and impaired memory (42 percent).
