Taking a puff of smoke, one or two cigarettes a day is not actually risky even if you are wearing a patch. But what would be normal and did not cause nicotine poisoning if you haven’t been wearing a patch would be risky with a patch. This will add to the quantity of nicotine that is already in the blood because of the patch and will cause nicotine poisoning. The same is true for using other nicotine therapy products like nicotine chewing gums or nicotine lozenges while you are wearing the patch. Smoking with a patch will also increase your tolerance to nicotine and will make you even more dependent on it.
