You wouldn't use it on friends in the first place.
To take this one step further I remember reading in Dragon years ago even though it was never specifically stated in the rules any kind of mind affecting spell such as charm person, suggestion, or ESP that a party member tried to cast on another party member automatically fails, as does intimidation and persuasion. Anything that gives one player the ability to take away another's freewill to make their own decisions wasn't allowed.
