Worry?: Only worry enough to stop smoking. Not sure why you coughed up the watery substance but it in itself is not a concerning symptom. Smoking however can lead to mouth and throat cancer, heart attack, stroke, COPD and lung cancer. It also puts you are risk for several other cancers. Please do everything you can to stop as soon as possible. You are young, if you stop now you can stay healthy.

Coughing fluid: Would not be concerned if no blood or thick green other colored mucus and if a single random event. Could be post nasal drip, or gastric reflux. f/u with doctor urgent care
