Since Adderall is a stimulant medication used for ADHD it probably has a vasoconstrictive action (similar to caffeine). Vasoconstriction means that the smaller blood vessels get slightly smaller in order for a larger volume of your blood to be directed to your larger organs. Because of this action, the blood vessels and capillaries that supply blood to you arms, fingers, legs, and toes become smaller which means slightly less circulation which can cause them to become cooler than usual. Cold hands, fingers, feet, and toes doesn't always mean that your blood is "thinner" and there is no literature on Adderall that states that Adderall "thins your blood".
