Drug
abuse vs drug addiction:

These
two words are often misinterpreted or used interchangeably.But to
tackle the problem one needs to understand that these two are not one
and the same thing.The major difference among the two are:

Drug
abuse is usually a choice which may appear casual but addiction is a
compulsion which may exhibit serious symptoms.

Drug
addicion is commonly associated with withdrawal symptoms while it is
not so with abuse

Addiction
is defined as a chronic mental disorder while abuse merely needs any
diagnosis.

Drug
abuse alters the brain briefly while addiction impairs it
permanently.

From
above mentioned differences it is clear that person starts using
drugs as choice which slowly turns into necessity.So, it’s  better
to recognise and stop the drug abuse before it becomes addiction.

How
does drugs affect our brain?

Initially
it interferes with the reward circuit of our brain,by flooding it
with chemical messenger dopamine.It controls body’s ability to feel
pleasure and motivates a person to repeat the activities that does
so.Therefore overstimulation of this centre makes person feel ‘high’
and motivates them to take drugs.As person continues to take
drug,brain cells ability to respond and secrete dopamine
decreases.This increases the tolerance of person persuading them to
take higher doses.

Long
term use can affect other centres such as:

Learning

Judgement

Memory

Behaviour

Stress

Brain
changes that occur over years affect person’s self-control and
interfere with ability to resist intense urge to take drugs.
