Abstract

BackgroundWomen with substance use disorder has attracted widespread attention as a prominent social issue. According to reports, physical exercise can improve the internal inhibition, effectively reduce the substance user’s drug graving, and improve withdrawal symptoms, however, the specific mechanism of internal inhibition should be further considered. This study was designed to determine the critical role of internal inhibition in the path of physical exertion affecting the drug cravings of women drug users.MethodsBy means of Physical Activity Rating Scale (PARS-3), internal Inhibition Scale and Drug Craving Scale, this study investigated the individuals with substance use disorder under rehabilitation in the women compulsory isolation rehabilitation center in Chongqing, China.Results(1) Women with traditional drug users had the strongest internal inhibition and new drug use disorder had the highest drug craving. The longer the duration of drug abuse, the lower the internal inhibition and the higher the drug craving. Women with moderate-intensity activity had the strongest internal inhibition and the lowest drug craving. (2) The physical activity intensity was negatively correlated with drug craving, positively correlated with intrinsic inhibition, and negatively correlated with drug craving. (3) Internal inhibition played a partial mediating effect between physical activity intensity and drug craving.ConclusionPhysical activity has a positive effect on inhibiting drug craving among drug addicts, while moderate-intensity activity seems to be more conducive to enhancing the internal inhibition of addicts, to improving their resistance to drugs, and thus more conducive to reducing drug craving.

Highlights

According to the Word Drug Report 2018, about 275 million individuals used drugs at least once in 2016 all over the world, which posing a huge threat to safety and health to humankind
In view of the limitations of previous studies, this study proposes the following assumptions: (X1) Physical activity was negatively correlated with drug craving. (X2) Internal inhibition was negatively correlated with drug craving. (X3) Physical activity is positively correlated with internal inhibition. (X4) Internal inhibition mediates the physical activity and drug craving of women with substance use disorder
In terms of drug graving, by within-group comparisons, it has been found that: (1) in new drug users, there were significant differences in drug graving among women with different drug use years (Group A < Group B, T = −2.52, P < 0.01), and (2) in traditional drug users, there were significant differences in drug graving among women with different drug use years (Group A < Group B, T = −3.96, P < 0.001), and (3) in mixed drug users, there was no significant difference in drug craving among women with different drug use years (T = −0.97, P > 0.05)

Summary

Introduction

According to the Word Drug Report 2018, about 275 million individuals used drugs at least once in 2016 all over the world, which posing a huge threat to safety and health to humankind. When an individual is craving for drugs, there will be a rift between his real self and his ought self, which will lead to negative emotions related to anxiety and depression (De los Cobos et al, 2011). On the basis of the self-medication hypothesis, young individuals with high social anxiety may use marijuana to alleviate emotional distress and respond to unpleasant social conditions (Khantzian, 1997), and individuals with higher drug dependence are more likely to be paranoid, and exacerbate psychotic-like symptoms (Musetti et al, 2016). Physical exercise can improve the internal inhibition, effectively reduce the substance user’s drug graving, and improve withdrawal symptoms, the specific mechanism of internal inhibition should be further considered. This study was designed to determine the critical role of internal inhibition in the path of physical exertion affecting the drug cravings of women drug users
