The most useful defence a tripper can have against bad trips is the ability to change the setting. Changing the music, the lighting, the room or just about anything can have a huge influence on the mindset of a person who is tripping and this makes it an invaluable technique.
Consider also that challenging moments in a trip can be an incredible opportunity for the development of one's character and you may come to the conclusion that many others have - that benzos are great but really ought to be a last resort. You can draw a parallel outside of the context of illegal drug use to those that drink heavily when times get tough. Instead of dealing with the hurdles that life presents they retreat to the bar, and they tend to be very immature as a result.
