Cannabis has been used medicinally for over 5300 years, and this film asks what fifteen hundred scientific and medical trials actually say about it now. Physicians and researchers walk through the evidence on camera: Dr. Donald Tashkin of UCLA's Pulmonary Function Laboratory discusses smoked cannabis and lung health, Dr. Donald Abrams of UCSF and San Francisco General Hospital speaks on its use in oncology, and Dr. David Bearman, a former director of the Haight Ashbury Drug Treatment Program, addresses its broader clinical history. The film also covers delivery methods, from smoking to tinctures to edibles, and their different effects and risks. One of its sharper points concerns government-funded studies designed to prove marijuana's harms that instead produced findings supporting its safety or benefit, a result the film treats as evidence of how politics has shaped the research record. Common claims about addiction, cognitive damage, and gateway effects are checked directly against what the cited trials found. The picture that emerges is a plant whose medical record is longer and better documented than its legal reputation suggests.
