A pet’s behaviour can change dramatically if they’re around weed smoke.
Pets can be affected by weed byproducts like secondhand smoke. Animals, especially cats and dogs, have more cannabinoid receptors than people, so they feel the effects of THC more strongly.
Not only are they quite sensitive to THC but their lungs can be easily irritated by smoke and may lead to issues like asthma.
Scientists found that inhaled cannabis smoke in dogs can induce respiratory tract infections such as bronchiolitis, and potentially cause pulmonary emphysema.
Secondhand smoke, of course, is also a problem; but so is what’s known as thirdhand smoke, which is defined as smoke that has penetrated household surfaces like furniture and clothes. Cats and certain breeds of short-snouted dogs are particularly sensitive to third-hand smoke.
