Cigars and Cigarettes
|
|
The nicotine in cigars and cigarettes
can prove toxic to a dog. It is important to remember that all leftovers
and butts are appropriately disposed of. Keep all packets well out of reach.
The very thought of eating the leftover parts of cigarettes to most (if
not all) people sounds repulsive but to many dogs it is most appealing
and some dogs have been known to eat an ashtray full of them. It is possible
for a dog to become addicted to nicotine.
Clinical Signs: Dribbling and Vomiting, May have diarrhoea
and show signs of abdominal pain, After a length of time, their muscles
might become weak, Twitching and convulsions, Even resulting in death

Everyone knows the Surgeon
General’s warning about cigarette smoking but what about cigarette eating?
Nicotine poisoning is a very real concern anywhere that a pet may find
cigarettes, cigarette butts, chewing tobacco, or even nicotine gum or patches.
Dogs, particularly puppies, tend to chew things up first and ask questions
later. Cats may find a cigarette butt to be a nicely sized pouncing toy worthy
of chewing.
Luckily for pets and small children, tobacco tastes terrible. Even chewing
tobacco must have flavorings added to make it something worthy of oral enjoyment.
Still, cigarettes have plenty of nicotine and even a small cigarette butt
can mean serious illness or even death for a small pet.
The toxic dose for nicotine in pets is 20-100 mg. A cigarette
contains 9-30 mg of nicotine depending on the type of cigarette; while
a cigarette butt contains about 25% of the nicotine of the original cigarette
despite its deceptively small amount of tobacco. (Smoking seems to concentrate
some of the nicotine in the tail end of the cigarette.) Cigars can contain
up to 40 mg. Chewing tobacco carries 6-8 mg per gram while the gum is 2-4
mg per piece and patches 8.3-114 mg. Smoking a cigarette yields only
0.5-2 mg of nicotine but eating one is a different ballgame as all of the
nicotine becomes available for absorption into the body.
Some good news is that nicotine is not absorbed directly in the acid
environment of the stomach; the nicotine must move past the stomach into
the small intestine for absorption. One of the first things nicotine does
in the body is stimulate the vomit center of the brain, thus inducing vomiting
which may save the patient’s life if there is more cigarette material in
the stomach.
SYMPTOMS OF NICOTINE POISONING
Signs begin as quickly as one hour post-ingestion.
Symptoms include:
Tremors
Auditory and Visual Hallucinations
Excitement
Vomiting and Diarrhea
Twitching possibly progressing to Seizures
Racing heart rate but slow heart rate with small doses
High blood pressure but at higher doses there is a circulatory collapse
It is easy to confuse nicotine poisoning with other poisonings such
as strychnine, chocolate, organophosphate insecticide, and certain molds.
Hopefully, there will be cigarette materials in the vomit to give away the
diagnosis.
Treatment
Washing out the stomach to get rid of any remaining cigarette materials
is helpful but is likely to require sedation. Since most patients are agitated,
this is often a good thing anyway. Seizures are treated with seizure
suppressing drugs. It is tempting to use antacids to protect the stomach
but as it is the stomach acid that is inhibiting the nicotine absorption,
it is best to avoid this therapy. If the pet survives the first 4 hours,
prognosis is felt to be good. Nicotine is inactivated by a healthy liver
and its metabolites are excreted in urine. After 16 hours, the nicotine ingested
should be gone.
