We sure can, Bill. Anti-smoking patches, like cigarettes and other tobacco products, can be dangerous for pets, depending on the circumstances of exposure. As they contain nicotine, they have the potential to produce severe vomiting, depression, elevated heart rate, a drop in blood pressure, seizures, respiratory failure and, in severe cases, even death. Based on this information, it is advisable to keep your nicotine patches out of the reach of pets, and dispose of used patches in a waste receptacle that they cannot get into.
