This study adopts the perspective of the Self-Determination Theory to look at the psychological experience of drug users and their decisions to take drugs or not, with particular emphasis on the concept of relatedness. To achieve this objective, a qualitative methodology was employed to explore the experiences of these drug users regarding how they take drugs and/or relapse. Theory-driven thematic analysis was employed to identify themes related to this topic. Results show that one’s psychological need for relatedness is an important determinant of whether one will take drugs or not, via the interaction mechanisms that exist in dimensions of affiliation and intimacy. While drug taking is a result of the modeling behavior existing in affiliated relationships, it is also a coping strategy for the ultimate satisfaction of psychological needs when human relatedness disappears. The implication is that significant others can develop unconditionally warm, caring, and empathetic supportive relationships with drug users, so as to enhance their fulfillment of psychological needs and reduce the risk of drug relapse.

The present paper examines the issue of hidden drug abuse in Hong Kong. Although official statistics show that the reported number of drug-abuse cases has been in decline in recent years, it has been reported that drug abusers tend to hide themselves at home to take drugs; thus, they are not discovered easily by the law enforcement and social control agents who report drug abuse cases to the Central Registry of Drug Abuse, resulting in the decrease in the reported number of drug-abuse cases. This “dark figure” phenomenon is a reflection of the official figure and reporting behavior, not the actual situation of drug abuse in Hong Kong. Through in-depth interviews of 30 ex-drug addicts, the majority of them started drug taking in early youth, the present paper identifies five stages of drug taking from social acquaintance to social isolation. It argues that although drug taking among abusers is a kind of social activity in their initial stage of drug use, they become socially isolated when their drug use is prolonged. Several reasons are identified, including users' easy accessibility to drugs and changes in the popularity of drugs and use of drug equipment. Most importantly, the hidden process is triggered and aggravated by numerous negative drug effects, such as decline in physical health, weak physical appearance leading to self-perceived discrimination, co-occurrence of psychiatric symptoms of increased anxiety and suspicion, and decline of trust among peers due to prolonged drug abuse. Possible solutions associated with clinical interventions, legislative policies, and law-enforcement operations are proposed.

Substance users use substances to tackle psychological stress, frustrations, poor social support and poor-quality relationships. Such experience resembles seeking a soulmate for receiving comfort, a sense of security and satisfaction to relieve feelings of loneliness. Against this backdrop, the study aims to develop a Soulmate Scale to measure substance use and loneliness. Data were collected from 507 drug abusers between 18–71 years of age who were receiving drug addiction treatment in Hong Kong. Both exploratory factor analysis and confirmatory factor analysis were conducted. Results show a valid and reliable scale with three factors: psychological release and shelter, staunch and supportive friendship, and spiritual solace and companionship. This study offers additional support for understanding the drug-taking experience of substance users from their perspective. The Scale provides a useful tool to assess the underlying reasons for substance users to persistently take drugs and formulate corresponding intervention plans to achieve drug abstinence.

Owing to the increasing prevalence of hidden drug abuse in Hong Kong, yet scarce relevant current local research, this study seeks to carry out an in-depth investigation into the experience of hidden drug abusers, paying particular attention to their relevance to social capital and social networks. Seventy-three abusers attending drug treatment programs were interviewed, and a thematic analysis was performed. The results indicate hidden drug abuse is popular in Hong Kong. Apart from the decline of public, large-scale discos and the change of the types of drugs abused to date, one important contributing factor is the drug supply and transaction networks, which are extensive and multilocused, but secretive, with high closure levels. This kind of network is supported by bonding, bridging, and linking social capital as well as by providing convenient supply modes and offering drug abusers psychological comfort and safety. These factors encourage the hidden drug abuse to prevail and allow drug abusers to remain unidentifiable.
