How much amphetamine will cause dilated pupils?

The dose of amphetamine required to cause dilated pupils can vary significantly among individuals, depending on factors like sensitivity, tolerance, and the presence of other substances. Typically, even relatively low doses, such as 5-10 mg, can lead to noticeable pupil dilation. However, higher doses are more likely to produce pronounced effects. It's important to note that the response can vary widely, and any use of amphetamine should be approached with caution due to potential health risks.
