No, dogs cannot smoke cigarettes like humans, but inhaling secondhand smoke or ingesting parts of a cigarette is extremely dangerous and harmful, causing respiratory issues, various cancers (lung, nasal), eye problems, and even nicotine poisoning, which can be fatal, especially in small dogs or puppies. Secondhand smoke contains thousands of toxins, and "third-hand" smoke residue on surfaces is also harmful as dogs groom and ingest it, so creating a smoke-free environment is crucial for their health.
Ingesting cigarettes can cause nicotine poisoning in dogs, with symptoms like vomiting, diarrhea, tremors, or lethargy. Since no symptoms appeared after 8 hours, severe poisoning is less likely but monitoring is crucial. Immediate veterinary care is advised if symptoms develop.
Second hand smoke exposure
Passive smoking is a health risk. There is no risk-free level of passive (second-hand) smoke exposure for animals or people. Companion animals, including (but not limited to) dogs, cats, birds, mice, guinea pigs and fish, are susceptible to the damaging effects of second-hand smoke.
Consider storage in sealed containers (reduce smell) and in locked upper cabinets (closer to the ceiling) when not in use. If smoking, keep pets in a separate and well-ventilated room (or outside), away from the smoke.

Secondhand (passive) smoke affects dog behavior: aggression, trainability, anxiety, fear, activity. Behavioral traits significantly changed when exposed to the owner's cigarette smoke. exposure to Environmental Cigarette Smoke; higher risk of behavioral problems.

Dogs exposed to secondhand smoke have more eye infections, allergies, and respiratory issues, including lung cancer. Cigarette smoke can stay in a room for a considerable period of time, even after the smell is gone.
Smoke inhalation caused by fires is a major cause of fatalities in animals. It usually involves inhalation of a complex mixture of toxicologic agents and pyrolysis products. Injury typically results from a combination of thermal injury to the upper airways, oxygen deprivation, and toxicity from inhaled materials.
Sources of Nicotine
In contrast, a dose of 9-12 mg/kg is considered lethal for most dogs, even less for cats. That is why ingesting just one cigarette, or cigarette butt, can be cause for concern, as the average cigarette contains approximately 12 mg of nicotine.
