The human brain is a miracle – there is nothing on earth that comes close to its capabilities. Although the brain and the heart are the only two organs that can’t regenerate, our brain can form new connections and pathways. Neuroplasticity is this amazing ability of our neural networks to grow and reorganize – to change and adapt as a result of experiences.

Until recently, it was thought that neuroplasticity stops after about 25, but with new research, we now know that it isn’t all downhill from there. Neuroplasticity can be facilitated by physical exercise, paying attention, and learning new things.

Physical exercise that increases blood flow to the brain is now a no-brainer. Paying attention is when we are doing something that is not out of habit – when we switch off autopilot and pay attention to what is happening. This is called mindfulness. Learning new things and being open to change becomes harder the older we get – and it will become increasingly more difficult if we don’t intentionally challenge ourselves mentally.

But what happens when drugs – any drug really, but drugs/substances of abuse are my topic here – enter the scene? Neuroplasticity then becomes the facilitator of addiction as our brain learns to adapt to the new stimulus, increasingly over time.
