Why do drugs change our emotions?

What drugs do is to mimic, with a magnifier effect, the action of substances that we have in our brain and that exist in brain circuits that are designed to respond to external stimuli and to trigger emotions in the face of these same external stimuli. When the brain is under the action of these drugs they somehow pirate the action of the endogenous substances and therefore the same external stimulus will have a different emotional response and therefore possibly less adequate and less determined by the personality of the individual himself. At Instituto de Medicina Molecular João Lobo Antunes (iMM) what we do is to learn the mechanism of action some drugs use and learn how they modify the activity of our brain and therefore how they modify our emotions.
