Mark Twain said it best: Giving up smoking is the easiest thing in the world. I know because I’ve done it thousands of times.
But the harsh reality is he’s right!
-
Carbon monoxide from smoke binds hemoglobin, lowering oxygen delivery to healing brain tissue.
-
Nicotine-induced vasoconstriction narrows cerebral blood vessels, further reducing blood flow and oxygen supply.
-
Recovery after stroke/TBI depends on the brain’s ability to rewire called neuroplasticity.
-
Animal studies show nicotine and other tobacco toxins slow down the growth of new neurons and reduce brain repair.
-
Tobacco smoke triggers systemic inflammation and oxidative stress.
-
Smoking roughly doubles the risk of another stroke or TIA.
-
Tobacco accelerates plaque buildup, raising the chance of blocked arteries in the brain and another stroke.
-
Smoking induces liver enzymes which can alter blood levels of drugs like antiepileptics, antidepressants, or anticoagulants you may rely on after brain injury, making it harder to maintain stable, therapeutic medication levels.
-
Studies link smoking after TBI to poorer attention, memory, and executive function recovery, the likelihood of depression and anxiety post-injury than non-smokers.
Enough?
Quitting tobacco after a brain injury can be tougher due to cognitive fatigue, stress, and old habits, but stopping is one of the single best things you can do for your brain’s recovery. Here’s a plan you might want:
| Step | Action | Brain-Friendly Tip |
|---|---|---|
| 1 | Set a Date to Quit | Choose a low-stress day and mark it on your calendar with an alarm. |
| 2 | Identify Triggers | Use a simple journal to note times/places you crave tobacco, for example, after meals or when frustrated. |
| 3 | Assemble Support | Tell your therapist or helpful friend and ask them for amiable reminders. |
Replace Routines with Safe Alternatives
-
Ritual Replacement
-
If you smoked “after meals,” replace it with a 2-minute deep-breathing exercise.
-
-
Fidget Reserves
-
Keep a stress ball or textured object to manipulate with your functional hand when cravings occur.
-
-
Oral Alternatives
-
Sugar-free gum or flavored toothpicks (available on Amazon) can copycat the sensation of smoking.
-
Build in Self-Compassion
-
“Slip” Plan
-
If you lapse, use a self-compassion break:
-
Acknowledge (“Oops, but that’s okay.”)
- Typical expression (“Many people relapse before quitting for good.”)
-
-
-
-
- Welcoming phrase (“I can try again tomorrow.”)
-
- After 24 hrs, 1 week, 1 month smoke-free, reward yourself with something youmost enjoy but healthy like a favorite meal.
Twain is correct! Setbacks are part of the process. But each smoke-free moment is a win for your brain. REALLY!
