Found this link where some guy complains that Adderall caused him to have heart ptoblems: http://www.adhdnews.com/testforum/test1962.htm

Is this true? Can Adderall cause heart problems in the long-run?

Let me put it to you this way. If you have heart problems you probably should not be taking stimulants. People with certain heart problems are at risk if they take stimulants.

Beyond that I have never heard of stimulants causing an otherwise healthy person to have heart problems.

Talk to your doctor
Me :D

I agree with speedo, any case of heart complications with Adderall that I have read, have always been with the existence of a pre-existing heart condition.
