Oxytocin has been referred to by silly names such as the love hormone and so on but there's no doubt that it plays a very important roll neurochemically in reinforcing life-affirming behaviors of bonding between mother and child, also couples. So it stands to reason that someone who feels the compulsive need to use meth after its initial positive reinforcing qualities are long gone is in futile pursuit of those feelings of connection, communication, communion and love for self and others felt during the honeymoon phase with stimulants.

There is emerging evidence that the neuropeptide oxytocin may be utilised as a treatment for various psychopathologies, including drug addictions. Here we used an animal model to assess whether oxytocin might be effective in the treatment of methamphetamine addiction. Sprague-Dawley rats were trained to lever press to intravenously self-administer methamphetamine under a progressive ratio schedule of reinforcement. Once responding had stabilised, one group of rats received escalating doses of oxytocin (0.001, 0.01, 0.1, 0.3, 1 mg/kg) administered intraperitoneally (IP) prior to daily self-administration tests, while other rats received vehicle. After these tests, lever-pressing was extinguished and the ability of methamphetamine primes (IP, 1 mg/kg) to reinstate responding was studied with and without co-administration of oxytocin (IP, 0.3 and 1 mg/kg). Results showed that oxytocin dose-dependently reduced responding for intravenous methamphetamine with an almost complete absence of responding at the highest oxytocin dose (1 mg/kg). Hyperactivity during methamphetamine self-administration was also dose-dependently reduced by oxytocin. Oxytocin (1 but not 0.3 mg/kg) also reduced the ability of methamphetamine to reinstate methamphetamine-seeking behaviour. In separate tests, oxytocin (IP, 0.3 and 1 mg/kg) robustly decreased the hyperactivity and rearing induced by methamphetamine challenge (IP, 1 mg/kg), producing activity levels similar to control animals. This study suggests that oxytocin may have a powerful inhibitory effect on the motivation to consume methamphetamine and on hyperactivity associated with acute methamphetamine intoxication. These results point to the potential utility of human trials of oxytocin as a therapeutic treatment for methamphetamine addiction.
