Smoking Rots The Brain: Surprise?

A new study published in the journal Age and Ageing brings a newish concern for smokers to the light.  Smoking–in addition the many directly physical issues it creates–rots the brain.  In particular, it damages memory, reasoning, and learning abilities in smokers.

It’s hard to say whether this is one of those “Well, Duh” moments or not.  Smoking is known to cause extensive damage to the lungs, throat, and cardiovascular system.  Its effects on the brain are a bit less direct.  Flow restriction in the carotid artery cuts blood supply to the brain.  This contributes to smokers having an increased chance of stroke.  At the same time, smoking addiction can cause withdrawal effects on the brain.

Still, these aren’t quite on the same level as Smoking ROTS your brain.  Research is still being done to connect smoking to cognitive decline.  This is one more in a number of pieces that continue to tell us just how bad smoking can be.

The study was conducted on 8,800 individuals over the age of 50.  The group was tracked over 8 years for the likely causes of cognitive decline.  Ultimately, smoking, high blood pressure, and being overweight all increased cognitive decline, but smoking did so the most.

The study came from King’s College London, a public university in the United Kingdom.  You can find the abstract here.

      Not surprising

        Id say it does rot the brain. Look at the stuff in cigs.

          Smoking messes with blood pressure, which can really mess with your brain, so this isn’t a surprise.

            makes sense… our whole existence is focused on supplying oxygen to our brain, we knew it couldn’t be helping…

              Glad I quit smoking. Although I’d say most things you consume now rot your brain.

                Definitely not a surprise, but have you heard that while smoking your reception and intelligence is slightly raised, since you are more aware? But then like any drug, when you are off of it, you decline.

                  It doesn’t really surprise me either to be honest. Seems like its bad all around really.

                    you know, cigarettes and coffee really helped my migraines… though, come to think of it, I havent’ had a migraine since I started vaping. Interesting… and great article, thanks for giving us thoughts to use our brains, keeps them in shape! I read somewhere that smoking helps people who have sarcoidosis and alzheimers. Probably by killing those brain cells!

                      Oh so that’s what it is. LOL I swear I feel like the older I get the more I am losing my mind. now I know what caused it.

                        I am not the least bit surprised at this. I am grateful that I have found something to get me off of those things too!

                          Go figure. No surprise here.

                            Makes me glad I never started smoking. I am a recreational vapor. I like 0mg fruity flavors.

                                I have also researched studies done on the nic patches on Alzheimer’s patients which said that nic helps improve cognitive function.

                                The problem I have with the ANTZ is that they lump nic with cigs, but they can’t deny nic’s medicinal powers when the study comes from the source of their funding.

                                  I wish I didn’t smoke so many last night with all the champagne. My throat is so disgusting right now. Glad my e-cig is in the mail.

                                    I’m glad I quit and here is yet another reason to celebrate my two years smoke free. Since nicotine has been shown to improve cognitive function in early Alzheimer’s patients it must be something else in the cigarettes that is causing the brain rot.
