Drug addiction is one of the major problems in developing countries. Since these countries have young populations, they are at greater risks of addiction. The young population expose to a higher risk as a major and the most vulnerable groups. Problems of puberty, adolescents and youth identity crisis and mental conditions can be considered as important factors for tendency of this age group towards addiction (
6). The use of drugs in adolescents who their friends have a positive attitude towards drugs is higher, even up to two-thirds of the causes for using the drugs is how much close friends talk about the drugs, and a friend suggests them to accept the use of drugs (
7). As well as pleasure, curiosity and escape of psycho-social problems are the major causes of early drug use for the first time (
8).
Heidari et al. concluded that low self-esteem, successive failures in life, and observational learning from addicted family members were the most common causes of tendency towards drug (
1). Yuki Maehira et al. investigated the factors influencing relapse of drug usage in Bangladesh during 5 months after drug withdrawal and concluded that the relapse rate is higher in women. In the male population, the most common factors influencing relapse included unstable housing, living alone, and high income. In the female population, the most common factors of relapse included having no child for emotional support and working as a sex worker (
9). Mir Lotfi et al. evaluated the attitudes of students in the dormitory of Zahedan City towards the drug abuse and they concluded that there are different causes for tendency towards the drugs while staying in dormitory is one of the most critical periods in people’s lives and necessary and appropriate measures should be performed to solve social and mental problems in this period (
2). Kilpatrick et al. also reported that the age of first use is obviously related to the future consumption patterns. As the drug usage is started sooner, it is correlated with the greater and more widespread use of other drugs (
10).
In our study, the causes of tendency towards drug use among the male population ranged from high to low were failure in life, escape from problems, staying awake, friends’ and peers’ insistence, pain relief, a positive attitude towards drugs, increase of the self-confidence, getting more energy, relaxation, recreation, learning from the family members, and gaining a new experience (curious). In the female population this ranking of causes included: failure in life, relaxation, recreation, increase of self-confidence, getting more energy, escape from problems, gaining a new experience (curious), pain relief, staying awake, friends’ and peers’ insistence, learning from family members, and a positive attitude towards drugs.
Eskandari investigated the factors affecting the tendency towards abuse of industrial drugs and classified the discussed factors that included: encouraging friends and conformity with their youthful lifestyle (hedonism), need of the euphoria, lack of tools for entertainment, preconceptions (e.g, relaxation, escape from problems, increase of self-esteem, etc.), addiction of other family members, curiosity (gaining a new experience), lack of public awareness of the effects (positive attitude towards drugs), and escape from the pressures of life (escape from problems), respectively (
11). As it is obvious, general tendency in the different studies are somewhat similar to each other and their differences may be due to the rankings which could be due to the studied people or the study conditions, but the overall structure is almost identical.
Molavi et al. have introduced depression, parental divorce, socializing with the wrong people, the desire to smoke and academic failure as the factors of tendency towards drugs (
12). In some cases there is also a high propensity to drug usage due to the lack of awareness of drug abuse (
13). Using the attend training of life skills can change people’s attitudes towards drugs effectively, especially in adolescence (
14,
15). More importantly, most of the causes of tendency to drug abuse are social, cultural, economic and psychological problems (
8). Authoritative parents are the most important factor in preventing the tendency toward drug use (
16). On the other hand, Berjas et al. in their research concluded that people’s family and peer groups could take them at the risk of drug abuse and addiction (
17). The influence of peers on adolescent drug tendency has been proven. It is assumed that the use of drugs by young people is in response to the influence of the peer group (
18).
The results of the present study showed that several factors in the etiology of drug abuse and addiction are effective. Therefore, in order to combat this phenomenon, any attempt that is carried out by considering only one factor is doomed to fail. On the other hand, all these factors cannot be influenced only by application of one method, however in a society several approaches should be used at the same time. Different approaches should also be applied in the prevention that they cover all the causes. Although the need to prevent is an obvious fact, choosing a prevention method also is not easy, because the causes of drug use are various, interconnected, and multidimensional (
19). Even among the studied genders in this study, prioritization of tendency causes to drug abuse is different.
One of the limitations of this study, according to the descriptive nature of the study, was the lack of the control group. Another limitation of the study was the low number of the female participants. Also, in some cases due to poor cooperation of the subjects, they were excluded from the study.
Finally, it can be concluded that the tendency towards addiction has many different causes, and these causes are slightly different based on the priority of the two genders. However, the main attention to the family, friends, and support from individuals in cases of difficulty or failure in life, as well as religious factors can prevent the further spread of addiction.
