Methamphetamine, a stimulant colloquially known as ‘crystal meth’, ‘crank’, ‘ice’, ‘chalk’ or ‘Tina’, is a highly addictive substance which can be snorted, smoked, ingested orally or rectally and injected. Amphetamine is powerful a psycho-stimulant which directly affect the autonomic and central nervous systems even in small amounts (
1). Data from neuroimaging studies, neuropsychological testing, and psychiatric evaluation indicates that heavy use of MA contributes to a variety of psychiatric pathologies, including psychosis, mood disturbance, suicidal ideations, anxiety, hostility, psychomotor dysfunction, deficits in cognitive skills, and, in extreme cases, paranoia, hallucinations, and delusion (
2). Immediately after ingestion of MA, users experience a number of highly desirable sensations, including a sense of euphoria caused by an elevated level of dopamine. Other desirable sensations associated with MA include increased productivity, heightened attentiveness and curiosity, hyper sexuality, decreased anxiety, and increased energy. The euphoric feelings vary in intensity and duration, depending on the route of administration, with smoking or intravenous injecting leading to intense, but brief, euphoria and with oral ingestion or snorting leading to a slightly less intense, but more long-lasting (
2). Previous findings showed that Substance use disorders often co-occur with eating disorders in female populations (
3). Substances associated with eating disorders include alcohol, tobacco, cannabis, cocaine, heroin and amphetamines (
4). Higher use among girls is consistent with other researches reporting gender differences in methamphetamine use. In a review of publications on methamphetamine over the past 30 years, Dluzen and Liu found that women tend to begin methamphetamine use at earlier ages, appear more dependent on it, but also respond better to treatment than do men. Methamphetamine use appears to be associated with depression in women, and women seem more committed to the drug, whereas men are more likely to use other drugs in the absence of access to methamphetamine. There is also evidence that methamphetamine use in some females, partly is due to their desire to lose weight (
5). In a study focusing on gender differences in drug use history among a broad cross-section (n = 350) of former clients from a large publicly funded treatment system, Brecht et al. found that initial methamphetamine tendency in females to lose weight is five times more than males (36% vs. 7%) (
6). Patients with bulimia nervosa are also more likely to report illicit drug use, particularly amphetamines, barbiturates, marijuana, tranquilizers and cocaine (
4). Because of an emphasis on diet and impotence in different social levels, factors associated with weight loss such as a body image require more attention (
7) Body image is a ‘‘multifaceted psychological experience of embodiment’’ which encompasses evaluative thoughts, beliefs, feelings, and behaviors related to one’s own physical appearance (
6) and body image can be influenced by factors such as physical growth, individual interactions with social environment, accidents, injuries (
8). On the other hand, the prevalence of body dissatisfaction is a major concern, because defects and mental disorders such as low self-esteem, depression, social anxiety, eating disorders, sexual disorders and diseases are associated with body deformity (
9). The most popular approach among people for negative body image is weight loss (
10). Overestimation of weight among normal weight adolescents and accurate perceptions of weight among overweight adolescents were associated with higher rates of eating behaviors disorders. In normal weight adolescents, use of all three substances (tobacco, binge drinking, and cocaine) was associated with each disordered eating behavior (
11). On the other hand, according to the results of psychological researches, diet can lead to food preoccupation and food deprivation, therefore, food Preoccupation is characteristic of those diets to lose weight. It is important for several reasons. First, it is believed to impair performance on a range of cognitive tasks. Compared to nondieters, dieters have been shown to display impaired performance on tests of reaction time, sustained attention and immediate free recall (
12). According to Johnson and Bedford, foods preoccupation starts early in life and does not change as one ages. Many weight concerned middle age women could have developed food preoccupation in their youth while young weight-concerned women have not fully developed an eating problem (
13). Cognitive food preoccupation can also lead to excessive eating or emotional eating. This type of eating is not as severe as binging but can also lead to obesity. A research performed on the eating disorder population has found that cognitive factors such as cognitive distortions, cognitive food preoccupation, and cognitive avoidance of emotion are all underlying factors which are strongly associated with development and maintenance of an eating disorder (
14). Also, the important role of family as the primary educator of social values, in the development of eating disorders should not be ignored (
7). In family systems theory, the effects of dynamics within the family have been shown to be as a significant risk factor for developing anorexia nervosa. Among these components, the component of flexibility has an important role; “family flexibility is the amount of change in its leadership, role relationships, and relationship rules” (
15). The results suggest that the transactional characteristics of an anorexic patient’s family organization include enmeshment, rigidity, overprotectiveness, and lack of conflict resolution and interactions avoiding conflicts (
16,
17). In fact, several researches and studies have been performed on the factors which affect addiction as social, economical as well as cultural factors, despite the fact there is a gap in the study of precursor psychological and personality factors affecting addiction, so it was tried to pave a new way to this subject in this study.
