Addiction: From coffee and tea to drugs of abuse

Drugs, I define it as "all that substance that affects the central nervous system". From coffee to drugs of abuse, they all have different effects, but they have something in common, they are addictive.

Fortunately, I and none of my close friends have had substance abuse problems, such as cocaine, base paste, LCD, etc. At least not for illegal drugs.

According to a paper "the brain of an addict" said that all drugs activated the reward circuit, releasing a large amount of dopamine, generating pleasure. This circuit is responsible for generating good experiences, activating when you eat a good meal, have sex and even when you interact with your group of friends. The dependence of dopamine by drugs is dangerous, when a lot of drugs are consumed dopamine levels of the brain increase, which causes the brain to adapt to these levels and when the drug is stopped the dopamine levels go down which can lead to depression, to maintain the levels of dopamine is generated dependence.

There are drugs that are more dangerous than others, those that produce less damage are tea or coffee, but like everything in life always in moderation, all excesses are bad, drugs of abuse are dangerous, not only for the person who becomes addicted, also their surroundings, addicted people stop working only think of their drug, if they do not have the drug they will get it by any means.

But everything in drugs is not bad, marijuana is used in medicine to relieve pain, coffee and tea keep you more active and alcohol (in moderation) is used to encourage parties.
