There are many stories about adderall and it's adverse effects so you cannot believe all of them. One of the main reasons you become reliant on adderall is the same for any other type of "study drug", and that is state dependent memory. While the effects of state dependent memory have not been quantified into an exact number, it does exist and will result in decreased performance when not taking the study drug. This creates the illusion of becoming reliant to preform day to day tasks.
This effect is seen in many other drugs such as caffeine or caffeinated drinks for the purpose of studying. Modafinil will have the exact same result on you as well. The reason it is not commonly heard about is that there is a lower percentage of people who actually use it.
I get it prescribed by the doctor. Dont waste your time or money and or risk your health with dark net amphetamines/ online pharmacy.
