Drugs directly or indirectly target the brain's reward system by flooding neurosmitters with an extreme amount of  dopamine, producing a euphoric effect. 

 

 

Our brains are hard-wired to remember and repeat activities that trigger our internal reward system.

 

 

Drugs physcially change our brains.  

 

 

Drug use is no longer a choice. 

 

 

These changes can be passed on to future generations. 

 

 

These future generations can have a greater propensity of becoming addicts.
