Yes. This is a product for adults who currently use nicotine. As with any product containing nicotine, you can become sick from taking in too much nicotine at once. We urge you to use one pouch at a time to get familiar with FR„™ and its effects on you. If you feel ill, STOP USING THE PRODUCT. If you experience a serious adverse reaction (such as an unexpected reaction with medications you are taking), CALL YOUR PHYSICIAN OR POISON CONTROL CENTER RIGHT AWAY.
