Human beings crave all sorts of things: coffee, sugar, sex, gambling, Xanax, porn, binge-watching TV shows, doomscrolling on social media, cocaine, online gaming, heroin, methamphetamines, hoarding. We each find different substances and activities alluring, and we develop distinct habits of choice. Cravings are an especially forceful and persuasive class of desires. When a craving strikes, it can be very tricky to resist or ignore. Sometimes we distract ourselves and move on with little effort. In other instances, it can feel nearly impossible not to act on a craving. What we’re drawn to, and what we’re vulnerable to, seems to reflect our individual personalities, preferences, cultural location, values, identities, coping mechanisms, and other life circumstances. So, why do we crave what we crave, and why are cravings sometimes so forcefully motivating?
One way to see the power of cravings is to think about substance addictions. Substance addictions present the sharpest example of how cravings seem to impact motivation and behaviour differently than other desires. Cravings make for one of the most challenging, baffling and terrifying aspects of addiction: no matter how devastating the consequences of ongoing drug use become for someone, as well as for those who love and care for them, no matter whether their addiction is no longer pleasurable, and no matter how adamantly they want and try to manage or stop their drug use, their attempts are continually overwhelmed by intensely motivating desires to engage in the addiction. This loss of control is often taken to be a defining feature of addiction.
Cravings are particularly common with certain drugs, including alcohol, nicotine, opiates and cocaine. Moreover, not only do cravings play this intrusive role in active drug use, but these unwanted desires can arise and be highly motivating even years into recovery from addiction. Craving is a major predictor of relapse. A systematic review of studies assessing the link between craving and substance use by using a method that evaluates craving episodes in real time in daily life found that in 92 per cent of studies craving was linked to substance use and relapse. Cravings can repeatedly override plans and resolutions to moderate or abstain from drug use, and this can be a disruptive, frustrating, demoralising and traumatising experience for those who battle these cravings – an experience that for some lasts a lifetime.
