Any correlation between increased cocaine use and the antidepressant Effexor XR?

At doses above 300mg, Effexor has some dopamine re uptake properties, explicitly, it can produce some similar effects to cocaine. Because a similar effect might be experienced by the patient, historic cocaine users might be at a heightened risk for relapse in an attempt to "sustain the high" or "verbs to block the re-uptake of dopamine."
Do you mean are cocaine users taking Effexor XR more promising to increase their cocaine use? The answer is no, there is no specified correlation. Actually, antidepressents are often prescribed to patients who are recovering from a cocaine addiction because cocaine results contained by increased seratonin levels, and antidepressents produce a similar effect but a safe and sound and controlled manner.
However, using cocaine while on Effexor XR is extremely death-defying as it can lead to seratonin syndrome, which can be lethal.
