Oliver Twist chewing tobacco bits contain approximately 5 mg of nicotine. The amount of nicotine released depends on how much you chew the tobacco bit and how long you keep it in your mouth. During one hour of use, approximately 2 mg of nicotine on an average are released from an Oliver Twist Tropical tobacco bit. Therefore, not all nicotine contained in a tobacco bit is absorbed. Some nicotine will still remain in the chewing tobacco bit after use. See the exact nicotine content per variant here.
