Depressants
The wearer will fall asleep or unconscious.
Hallucinogens
The user will hallucinate (see something that actually does not exist).
Stimulants
Accelerate the work of organs such as heart and brain so that users feel more energetic for a while. Because the organs of the body continue to be forced to work beyond normal limits, long-time nerves will be damaged and can lead to death.
Addictive
Users will feel addicted so will do a variety of ways to continue to consume them. If the user can not get it, his body will be in critical condition
Doing various ways to get drugs continuously
Users who are already on the addiction stage will do various ways to get drugs back. For example, students can use their tuition to buy drugs if they do not have the money supply.
In fact, they can steal money from parents, friends, or neighbors. It is certainly going to disrupt social stability.
With a damaged body condition, it is impossible for the user to learn, work, work, or do other positive things.
