Effect of Drugs on Brain

The neurostimulators or psychotropic drugs bind to the receptors in the brain and start an unnatural chain of reactions causing electrical changes and stimulate neurons to release large amounts of drug associated neurotransmitters. Some drugs may lock into the neuron and act like pump. The locked in psychotropic drugs extensively stimulate the neurons to release more and more neurotransmitters. There exists a natural biobalance of neurotransmitters under the normal conditions of neurophysiology, but certain drugs may block reabsorption or reuptake of neurotransmitters, leading to behavioral changes. The drug addiction is a complex brain disease. There could be compulsive and uncontrollable craving for drugs. The compulsive desire for drugs may lead to such a behavioral change when one ignores all the moral values of the life and society to acquire a drug. The habitual use of a drug severely affects the neurophysiology and leads to addiction.
