A very strange individual who has fallen in love with the very strange drug DXM. Once the good effects have worn off, they often come crawling back to society, blaming the drug for their insanity.
Johnny the syruphead drank cough syrup, said "I'm messiah." His friends abandoned him. Some time later: "It was the NyQuill ... The Nyquill!!!!"

A chronic recreational user or addict of the anti-tussive drug, Dextromethorphan (DXM) that is commonly found in many over-the-counter cough and cold remedies.
Syrup heads typically exhibit the following adverse reactions: impaired judgment and mental efficacy, paranoid ideation, dysphoria, blurred vision, headache, dizziness, syncope, slurred speech, ruddiness of complexion, muscular twitching, extremity numbness and tremors, nausea, abdominal pain, vomiting, decreased thermoregulation, hypertension, liver damage and irregular heartbeat. A good round of repeated and violent vomiting is sometimes the only thing separating a syrup head from a horrid long night in the ER.
