What happened
The study, from the University of Washington's Addictive Behaviors Research Center, involved 123 undergraduate smokers who wanted to change their smoking but were not in a quit programme. Each took part in a cue-exposure task designed to bring on the urge to smoke.
They were randomly assigned to one of two groups. One received brief mindfulness-based instructions built on “urge surfing,” a technique from Marlatt's 1985 work with Gordon. The other received no instructions.
The two groups “did not differ significantly on measures of urges.” But over a seven-day follow-up, the group given the instructions smoked significantly fewer cigarettes. The authors concluded that the techniques “may not initially reduce urges to smoke but may change the response to urges,” and described their data as preliminary. The study was published in Psychology of Addictive Behaviors.
A review by Stuart Ferguson and Saul Shiffman, also from 2009, looked at urges set off by cues. It describes them as “intense, episodic cravings typically provoked by situational cues associated with drug use.” Field studies, the review reports, show that such cravings are “substantially responsible for relapse to smoking” but that “smoking can often be averted by coping responses.”
Neither paper puts a number of minutes on a single urge. iCanQuit, a quit-smoking service run by the Cancer Institute NSW, part of the New South Wales Government, tells smokers: “Each craving usually lasts only 10 to 20 minutes.”
What it shows
Urges come in episodes, often set off by something in the surroundings. In the urge-surfing study, the urge itself was just as strong in both groups. What differed was what people did next.
All of this research is about smoking. We draw on it for one general point: an urge comes as an episode, and an episode can end without being acted on. We do not claim that sexual urges follow the same timetable as nicotine cravings.
About Unlure
How Unlure uses this
Unlure is built around the response to an urge. When one arrives, every way to turn protection off or unblock a site starts a three-day wait, and protection stays on the whole time.
Like the urge-surfing instructions, the wait puts time between an urge and an action. Unlike them, it does not depend on remembering a technique in the moment.
If the urge has passed by the time the code appears, doing nothing is enough. The request lapses a day later and protection stays on.
Unlure is a blocking tool. It does not treat any condition. If urges feel out of control or are causing you distress, talk to a qualified professional.
