Between 2009 and 2013, Tikun Olam conducted an observational study of residents at the Hadarim Retirement Home on Kibbutz Na’an in central Israel who took medical marijuana via vaporizer, powder or oil. Over the course of the study, the 19 elderly participants experienced weight gain, increased calorie intake, longer and better sleep, stabilized hemoglobin levels and decreased use of painkillers, sedatives and antidepressants. “We’ve already learned to prolong life,” says Hadarim’s head nurse, Inbal Sikorin. “Marijuana adds to the quality of life.”
