Would the operant conditioning from A Clockwork Orange work?

The technique is used and is called "Aversion Therapy." It is not commonly used because the effects do not work on everyone and do not always last. There are many types of aversion therapy that do not include the drug/film combination as in the film for example: someone that wants to stop eating fries have been told to chew a few fries, spit them into their hand and moosh them around in their hand while looking at them and then put them back in your mouth and back and forth. This will cause a natural anxiety and negative association towards fries which will make you not crave them and be disgusted when faced with them.
