What are ways to safely dispose of cannabis waste?
Mix cannabis waste with at least 50% non-cannabis material (e.g., food waste, sawdust) to render it unusable before disposal in a licensed landfill. Recycle eligible packaging, such as glass, aluminum, and certain plastics, through designated programs. Where permitted, incinerate THC concentrates and contaminated materials to ensure complete destruction and prevent environmental harm.
Note: Disposal procedures vary by location, so it is important to consult state and local authorities to ensure compliance with specific cannabis waste management laws.
