The results, Klein says, have been outstanding. Not only did participants experience dramatic physical results, including healthy weight gain and the reduction of pain and tremors, but Hadarim staff saw an immediate improvement in the participants’ moods and communication skills. The use of chronic medications was also significantly reduced, he reports.
In 2009, Zach Klein, a graduate of Tel Aviv University’s Department of Film and Television Studies, directed the documentary Prescribed Grass.
Through the process, he developed an interest in the scientific research behind medical marijuana, and now, as a specialist in policy-making surrounding medical cannabis and an MA student at TAU’s Porter School of Environmental Studies, he is conducting his own research into the benefits of medical cannabis.
Using marijuana from a farm called Tikkun Olam — a reference to the Jewish concept of healing the world — Klein and his fellow researchers tested the impact of the treatment on 19 residents of the Hadarim nursing home in Israel.
