Cats can indeed get high from weed smoke, specifically from the THC (tetrahydrocannabinol) in marijuana. When cats inhale secondhand marijuana smoke, THC interacts with cannabinoid receptors in their brain, causing them to experience effects similar to being high. However, unlike humans, cats do not enjoy this state, and it can make them anxious, agitated, disoriented, or fearful. Cats are particularly sensitive to THC, and even small amounts can cause serious side effects such as lethargy, lack of coordination, dilated pupils, vomiting, tremors, or seizures. Exposure to marijuana smoke or ingestion of marijuana products is harmful to cats and should be avoided. While CBD (cannabidiol) and hemp products that contain little to no THC are generally considered safe and may offer some health benefits for cats, marijuana with THC is toxic and dangerous for them. It is best not to smoke weed around cats or expose them to marijuana in any form to prevent these harmful effects and potential veterinary emergencies.
