The simple answer to this questions is “yes” nicotine is considered a drug and one a very powerful drug at that. It affects the brain in much of the same way as does cocaine and heroin.
A drug addiction is defined as – a chronic, relapsing brain disease that is characterized by compulsive drug seeking and use, despite harmful effects and consequences (that sounds familiar). The reason it is considered a brain disease is because drugs change the brain by changing the structure and how it works. According to the National Institute of Drug Abuse there are long-term changes in the brain caused by prolonged nicotine exposure which results in addiction. Of course any of us trying to quit smoking know that we are addicted but did you know that you are addicted to a powerful drug. This plays into the physical addiction aspect which is most cases doesn’t even come close to the psychological addiction aspect of things.
Remember the more you know the better you can prepare yourself when quitting smoking. Understand what you will be dealing with and the challenges ahead, plan to overcome obstacles and plan to succeed.
