My uvula is swollen fron snorting a substance no pain just feels real weird?

SIMPLE: Stop snorting the substance and it should get better, it is irritated by the 'substance'.

Beware!: Snorting substances has been known to cause tissue damage to the lining of the nose and pharynx including severe necrosis. E.G. Snorted Cocaine or crushed vicodin have both been associated with significant tissue death in the nose and throat. Not a good idea for many many reasons.
