The psycho-stimulant drug, commonly known as Ecstasy, is also known under other names, such as MDMA, E, or X. MDMA is an acronym for 3- or 4- Methylenedioxymethamphetamine and, as you can see in the scientific name itself, it is an amphetamine. Though Ecstasy is used, in rare cases for therapeutic benefits,  it is illegal in many countries due to recreational drug abuse.  MDMA induces feelings of safety, euphoria, intimacy, and reduces feelings of depression, anxiety or paranoia.
During use, Ecstasy abuse can be measured by behavioral changes, such as an unwillingness to pick a fight, happy or trance like state, and the absence of fear or anxiety in high stress or dangerous situations. In the workplace, someone who normally stresses out, even to a slight degree, is temperamental, or is very aware of physical danger may be abusing Ecstasy if these specific temperaments change in a happier, more positive or less afraid direction.
After abuse is terminated, withdrawal symptoms are much more noticeable.  Anxiety and heightened paranoia are two of the more major psychological side effects, but there are more. Sudden tiredness, irritability, intolerance, and prolonged depression can also occur. The ability to focus or pay attention is strongly impaired. The lack of willingness to work or be motivated or internally driven is a usual withdrawal symptom of Ecstasy, since the serotonin levels have dropped. Depression is also due to depleted serotonin levels, which means that suddenly emotionally burdening someone who has just stopped using Ecstasy can be more than they can handle, and might even bring on a physical danger to both you and them. In short, abusers may not be as dangerous during direct drug abuse, but they will become increasingly dangerous to you and others if they are denied their drug. 
Extreme exhaustion is more likely during withdrawal from Ecstasy if there is also slight aching in the body, vertigo when moving or a severe loss of appetite.
Due to the over-stimulation of the “feel-good” serotonin and dopamine receptors in the brain, withdrawing from Ecstasy can also induce long-term or chronic depression if the serotonin levels do not regain normal function later on. 
Hallucinations are more common with MDMA than with other amphetamines, as well as nausea, higher blood pressure and body temperature. Vision can also become blurred and muscles are more likely to cramp.
