On the journey of growth, danger often wears the mask of 'curiosity' and 'relief.' The core focus of this lesson is to definethe essence of drugsand the irreversible nature of addiction.

What we refer to asdrugs (drug), are not ordinary medications, but rather opium, heroin, morphine, marijuana, crystal meth, cocaine, and other narcotics and psychotropic substances regulated by national law that can lead to addiction. They act like sophisticated 'biological hackers,' infiltrating the body and forcibly rewriting the brain'sreward system.

The Logic of Addiction's 'Hijacking'

When you try that so-called 'first puff' out of curiosity, addictive substances mimic or trigger extreme biochemical reactions, forcibly altering the balance of neurotransmitters in the brain (such as dopamine). This change is oftenirreversibleand leads individuals to lose control over their behavior, plunging them into a pit that drains money while destroying personality and physical function.

Tobacco: The 'Sentinel' of Drugs

Why is tobacco often considered a 'soft drug'? Because nicotine in tobacco has extremely strongdependence. For teenagers, smoking often serves as a potential gateway to more dangerous substance abuse. In social settings, tobacco is highly pervasive—this compromise of taking that 'first puff' often weakens psychological defenses, making individuals far more vulnerable when facing real drug temptations later on.
