I only take adderall once a month but when I do take it i take between 40 - 60mg of instant release In the span of the 3 hours. Can this cause any harm to my brain?
There's always a risk with pretty much all stimulant.. It is fairly minimal if this is all you take though. Staying hydrated and sleeping well before and after usually cancels most of it too. What you do and other substances you take at the same time also makes a big difference. Same as your overall health. The risk is fairly low, but to answer your question, it definitely can cause damageOh so there is chance for neurotoxicity in higher doses?
