Here's why:
* Nicotine is a highly toxic substance, but it's not that potent. While nicotine can be deadly, it takes a significant amount to be fatal.
* Horses are large animals with a higher tolerance to certain substances. The amount of nicotine in a single drop wouldn't be enough to cause immediate death in a horse.
* The "one drop" claim is likely exaggerated. It's a way of highlighting the danger of nicotine, but it's not accurate.
However, it's important to remember that:
* Nicotine is still dangerous. Even small amounts can cause poisoning in horses, leading to symptoms like vomiting, diarrhea, tremors, and even death.
* Never intentionally give nicotine to any animal. It's important to keep cigarettes, vaping products, and other nicotine sources out of reach of animals.
If you suspect your horse has ingested nicotine, contact a veterinarian immediately.
