<human>:  Would a Monoamine Oxidase candy bar cheer up a depressed friend?
<bot>: No, depression is a mood state that probably can not be helped by eating a Monoamine Oxidase candy bar. Depression is caused by low levels of serotonin, dopamine and norepinephrine and Monoamine Oxidase breaks down neurotransmitters and lowers levels of serotonin, dopamine and norepinephrine, so it would not.
