Sativas are more likely to induce visuals and slight auditory hallucinations, and they are less likely to leave you tired and burnt out. They're also more likely (than indica) to be used to treat depression and phantom pain. The high seems to be centered in your head, making you feel 'floaty.'

Indicas are more likely used to treat anxiety and insomnia. They are also more likely to leave you burnt out and sleepy. An indica high will generally last longer than a sativa high. It creates a body-buzz like Stealth331 said.
