Psychotic Syptoms:
Although it is rare, Ecstasy can produce a state of intoxication which mimics a psychosis, such as paranoia, but this does not usually last for more than a few days.(Kemmerling et al. 1996) (Williams et al. 1993). This normally includes delusions of persecution, ideas of reference (believing you are the center of everyone's behaviors, speech, and even thoughts), depersonalization, and derealization. It most frequently occurred in "regular" or "experienced" users. In the cases reported, the recovery percentage is poor (34.5% full recovery) (Baggott et al. 2001).
Affective Symptoms:
This typically included anxiety shown through acute panic response or chronic panic disorder. In some cases the panic attacks would quickly resolve although in others anxiety or panic attacks could persist for weeks. The recovery percentage from the cases reported was very good.
Depression:
Often, as the euphoric effects start to wear off, users fall into a low mood level which in some cases could be labeled as depression. This is known as the "come-down." Chronic ecstasy use is often followed by a longer lasting depression. Some evidence suggests that depression may be due to low serotonin levels in the system controlling mood, appetite, sleep, and sex drive. Serotonin levels are low for a week in this second system (Molliver et al. 1989). Depression can lead to suicide.
Depersonalization and Derealization:
Depersonalisation refers to the feeling that one is not 'real', and that one is detached and unable to feel emotion. It can be very unpleasant (Simeon, D. 2004). Derealisation is the feeling that the surroundings feel different or "unreal."
Impaired attention and concentration
