Answer:
depression and suicidal ideation
Explanation:
As the name suggests central nervous system stimulants increase the overall activity of the nervous system. Stimulants make a person more active they require less sleep and are at an elevated state overall. The body becomes used to the better mood associated with stimulant intake. So, much so that this state would not develop naturally but only with stimulants.
Withdrawal involves feelings of depression, having less energy, overall in a low state. A severe case of withdrawal would be a lack of will to live. This causes suicidal thoughts to develop.
