Cannabis EdiblesCannabis Poisoning

Cannabis poisoning occurs when a person uses or consumes too much cannabis at one time. Compared to smoked cannabis, edible cannabis (food or drink products that contain cannabis) has a higher risk of poisoning. Edibles take longer to take effect, so people may eat more edibles while waiting for the "high." This can lead to the person eating too many edibles which can result in cannabis poisoning.

Because of their smaller size and weight, children are more sensitive to the effects of cannabis and are at higher risk for cannabis poisoning. They may have problems walking, sitting up, or have a hard time breathing. To learn how to maintain cannabis safeguards, visit this page on Cannabis Safety Measures
