In general, symptoms of drug usage do not pop out alone, and usually there is more than one symptom that you will be able to notice. Depending on a person's body structure, age, and gender, different symptoms will show up in a different order, strength and combination.

Of course, every drug has its own influence on the human body, and depending on which chemical substance – it can slow down or speed up a person's brain activity. Professionals often call this: "effects on the executive functioning areas of the brain." Executive functioning areas of the brain are responsible for activities like planning, organizing, acting when it is time to act, as well as delaying or preventing action (inhibitory functions) when appropriate.
The executive brain functions are performed in the frontal and prefrontal cortex. When a person starts using drugs – the inhibitory functions of the brain are specifically impaired, which means that his or her brain stops to delay or prevent impulses that would have been stopped in regular conditions. These changes in the human brain can lead to aggression, sexual, criminal, or other activities that can have devastating consequences for the addicted person. Until the age of 25, the human brain is in the process of active and rapid development, and, therefore, is not fully mature. Drug abuse in childhood and teenage years can cause devastating effects on the youngger person's ability to perform important executive functions.
