Drug brain interactions
This site has interesting animations explaining the effect of the most common drugs in the brain. It made a lot of sense to me when I learned ten years ago or more the effect of alcohol in the brain, letting neuron membranes all confused and allowing substances to travel back and forth without control.
I am very convinced that drugs do not have magically the ability to develop new programs on the brain. Their only possibility is to bring programs down and by doing so, they inhibit controls in place and people can show behaviors that they usually they don't exhibit. They might over a period of time develop new habits which are in a way new programs.
Looking at the biochemistry of the drug-neuron interaction only re-affirms this thought.
Particularly interesting was to see the effects of caffeine and long term use of nicotine.
