The common mechanism of action is what really is a track called the path of the mesolimbic reward, which is a neurotransmitter is dopamine. All addictive drugs that stimulate the brain reward circuit d.

This circuit activates a region of the limbic system is what regulates emotion and behavior and is what gives us the perception of pleasure. When neurons release certain neurotransmitters, and these circuits are activated when we feel good. However, the drugs can alter the mechanism of reward.

What do these drugs is to teach your customer to take them again and again. It’s like a reward system booster.

Prolonged use of a substance can alter these brain systems as the brain require the presence of exogenous substances to maintain their homeotasis. Initially, the consumption of opiates increase dopamine levels, but eventually you need the addition of more substance to achieve the same effect of euphoria or pleasure.

Have published several studies showing that the greater the activation of the dopamine system, the greater the experience of euphoria. Therefore, it is known that dopamine is the critical element and that all addictive substances alter dopamine levels in this part of the brain.

The idea that everything can be related to a single chemical has a keen interest to scientists and has changed the way you watch a wide range of sponsors. Dopamine is not only a chemical that transmits pleasure signals but is also the most important molecule involved in addiction.

This does not mean that dopamine is the only chemical that determines the chronic drug abuse, we know that the brain is much more complex. Drugs modulate a wide variety of brain chemicals each of which interacts with others.

The hypothesi of dopamine provides a framework for understanding a genetic code (such as the tendency to produce little dopamine for example) can interact with the environment and create serious dysfunction in behavior.
