Poll: Marijuana safer than opioids, but moms shouldn’t use

Americans think it's safer to use marijuana than opioids to relieve pain, but they were less comfortable with children and pregnant women using pot to treat medical conditions, according to a new Yahoo/Marist poll released Monday. Two-thirds of the respondents in the telephone survey said opioid drugs such as Vicodin or OxyContin are "riskier" to use than pot, even when the pain pills are prescribed by a doctor.
