What Could Lead to Drug Addiction ?

Experimentation with psychotropic drugs for fun and elated feelings could activate certain receptors of our brain to such an extent that one would feel depressed without taking a particular drug. When a person starts taking a psychotropic drug, he/she enjoys the drug's euphoric effects. Repeated desire for elevated mood and a kick makes one addict for ever. The drug addiction is mostly unintentional as a person who begins with casual use of a drug does not know that the substance could become his/her daily desire. The drug associated altered neurophysiology leads to drug dependence. The drug related release of neurotransmitters may alter the ultrastructural architecture of neurons at a later stage. Some drugs may lock into some neurons and act like a pump and extensively stimulate the neurons to release more and more neurotransmitters. There exists a natural balance of neurotransmitters under the normal conditions of neurophysiology, but certain drugs may block reabsorption or reuptake of neurotransmitters, leading to behavioral changes altered physiology. The drug adiction is a complex brain disease. Despite the fact that the high effects of a drug are short term phenomenon, one finds it difficult to quit the habit. The compulsive and uncontrollable craving for a psychotropic drug leads to such a behavioral change that one would ignore all the moral values of the life and society to acquire a drug. The habitual use of a neurostimulator or psychotropic drug severely affects the neurophysiology and leads to drug addiction.
