How will i know what does amphetamie do if you don't have adhd?

Greater focus: Just like people with adhd stimulants with help other with focus and increased concentration, unlike antidepressants, which will not make people without depression or anxiety more serene or happy.

IF YOU DON'T NEED: People who don't need stimulants will get a more intense awareness which can become very uncomfortable and more energy as if you are riding a rocket - also uncomfortable. The heart beats faster, blood pressure goes up and ordinary sports you can generally do can leave you breathless. Appetite drops and sleep can be disrupted. Not actually desirable.

Adrenalin rush: Amphetamines will cause an increase in alertness, an increase in energy level, increase heart rate and blood pressure. they can cause jitteryness, irritability and headaches.
