Adverse drug reactions are appreciably harmful or unpleasant reactions resulting from an intervention related to the use of medical products, which predicts hazard from future administration and warrants prevention or specific treatment, or alteration of the dosage regimen, or withdrawal of the product. Given medical case reports extracted from MEDLINE, the task is to classify whether the case report mentions the presence of any adverse drug reaction. Classify your answers into non-adverse drug event and adverse drug event.

Example Input: Trazodone therapy was continued or reinstated shortly after the hypomanic episode without further evidence of hypomania.
Example Output: non-adverse drug event

Example Input: The authors think that although lamivudine is widely used and well tolerated, it can cause ADRs, which are reversible after drug withdrawal.
Example Output: adverse drug event

Example Input: We present a patient who developed extensive Molluscum Contagiosum (MC) lesions shortly after being started on HAART.
Example Output:
non-adverse drug event
