Hello doc how bad is snorting ritalin (methylphenidate)? iv been doing it for years and i dont know why really i think i like the punishment...

Habit/addiction?: Misuse of any medication is generally inappropriate. Ritalin (methylphenidate) is a controlled substance & to misuse the drug especially chronically likely suggests the possibility of a substance abuse disorder. Professional help for management of dependency and likely a psychiatrist / psychotherapist to pinpoint & effectively address the factors that predisposes to high risk lifestyle is very impt. Take care.
