Are there different effects depending on the amount of Ritalin taken?
Yes, but even at low doses Ritalin can produce a high. Larger doses can make people exhilarated and excited. With large doses, even moving can be more difficult. These large doses can make people agitated, confused or paranoid (believing that people are out to get them). Large doses can also cause people to hallucinate (imagine things that aren’t really there). With high doses, their muscles twitch, pupils dilate, and their faces turn red and your heart beats faster and harder. They can even develop a fever and start sweating. Very high doses can make you delirious. You could go into seizures and even go into a coma. If people inject Ritalin and share needles, they have a greater risk of certain diseases, including hepatitis and HIV (the virus that causes AIDS).
