SafetyCancerHempIndustry Why This Matters Peer-reviewed research shows cannabis beverages help people drink significantly less alcohol, yet the very products proven to reduce harm are the ones the November ban would eliminate first. Clinical Summary Prevention.com article where a toxicologist discusses the potential cancer link to common herbicide/weed killer products used in gardening. While not directly cannabis-related, this is relevant to cannabis cultivators and the broader agricultural health conversation. The article examines the ongoing debate around glyphosate-based herbicides and their classification as probable carcinogens by IARC. For cannabis growers, this raises questions about pesticide residues in cannabis products and the importance of organic cultivation practices and rigorous testing for contaminants in the legal cannabis supply chain. Dr. Caplan’s Take “We have clinical evidence that cannabis beverages reduce alcohol consumption,a leading cause of preventable death, and the federal government is about to ban them; that is a public health failure, full stop.” Clinical Perspective HERBICIDES, CANCER, AND CANNABIS Prevention.com’s article on herbicide cancer risks is directly relevant to [cannabis cultivation](https://cedclinic.com/growing-medical-marijuana-at-home-guide/). Glyphosate—classified as a ‘probable carcinogen’ by IARC—raises concerns about pesticide residues in cannabis products. Testing standards vary dramatically between states, and many don’t test for the full range of potentially harmful agricultural chemicals. For immunocompromised patients, contamination risk is amplified. Organic cultivation, comprehensive contaminant panels, and transparent supply chain documentation are fundamental to patient safety.
