New synthetic drugs are a new phenomenon that is expanding in many countries. NSD mimic the effects of traditional drugs phenomenological, but retain the hallmark of legal substances. NSD legal status is due to the fact that theses new substances are controlled by the United Nations Single Convention on Narcotic Drugs of 1961 or the UN Convention on Psychotropic Substances, 1971. To the Czech Republic this trend came somewhat later than in neighboring countries, and especially in 2010, when sales NSD was mainly in shops. This sale was completed in April 2011 becouse of entering 33th NSD to the list of psychotropic and narcotic substances and moved mostly to the internet. NSD composition is often changing, due to disabling preparatory material, it follows that the risks associated with the use of NSD are unpredictable. The research objective of this study is to determine the acquisition and distribution of NSD between problem drug users and also to map the most widely used NSD among this population.The main purpose of the research is to bring knowledge (as it's called, how it look, what it contains, where and from whom it receives, how much it costs). The survey was made up of semi-structures interviews (qualitative part) and structured questionnaires (quantitative part). Respondents were selected...

Drug trade is a part of non-observed economy in the system of national accounts. Estimations of drug trade were made from demand side based on estimation of drug consumption. This needs estimations of drug users, which was possible to estimate from drug use prevalence in last year. Several surveys done in society were the data source. Other information from the surveys was information about frequency of drug use. Several research studies gave information about consumed drug quantity by one opportunity. Police and customs have a common database about drug seizures. The database is source for information about import and export of drugs, drug purities by production or import and by consumption or export. Police reports drug prices also. The physical indicators of the drug trade are recalculated by wholesale and retail prices into financial indicators, which are possible to record into system of national accounts.

La ricerca ha l’obiettivo di esaminare modelli etnici nella criminalità organizzata, esplorando, in particolare, caratteristiche strutturali del crimine e il ruolo dell’etnicità nel mercato della droga in Italia. La tesi si sviluppa in due livelli di analisi, macro e micro. Il livello macro esamina le tendenze della criminalità degli italiani e stranieri nel mercato della droga in Italia, attraverso l'esame dei dati ufficiali sugli autori di reato riportati all’Autorità giudiziaria in Italia per violazione della legge sugli stupefacenti, dal 1991 al 2008. Il livello micro esamina la struttura di una rete criminale composta da italiani e stranieri coinvolti in una serie di attività illegali relative al traffico e spaccio di stupefacenti scoperte in Italia (Operazione Luna Blu), attraverso l’esame delle comunicazioni (intercettazioni telefoniche ed ambientali) incluse nel caso studio. L'analisi di rete (SNA) ha permesso di ricostruire la struttura della rete criminale, identificare il ruolo dell’etnicità nei processi di traffico e spaccio di stupefacenti riportati nel caso studio, e verificare ipotesi relative a modelli etnici nella criminalità organizzata nel mercato della droga. / The research aims to provide a further understanding of ethnic patterns in organized crime, accounting for the structure of crime and ethnic features therein, with a specific focus on the Italian drug market. The research is developed in a two-level analysis. The macro level of analysis provides a general understanding of patterns of ethnic involvement in the drug market in Italy through the examination of official data on drug crimes and offenders reported to the Judicial Authority in Italy, from 1991 to 2008. This is to examine trends in the degree and type of involvement of Italians and foreigners in the Italian drug market over time. The micro level of analysis provides a further elaboration on the structure of crime and ethnic patterns in organized crime in the Italian drug market. It illustrates the structure of a criminal network composed by Italian and foreigner offenders involved in a series of drug distribution operations targeted in Italy (“Operation Luna Blu” case), through the examination of intercepted communication data (wiretaps and electronic surveillance records) included in the case study. Social network analysis (SNA) is applied at this level of analysis as the analytical framework to reconstruct the criminal network structure, identify organizational patterns along ethnic lines, and test hypotheses related to ethnic patterns of interaction amongst Luna Blu network participants.

Darknet är en del av den djupa webben, som är en icke indexerad del av internet. Det används för olika ändamål, till exempel att köpa läkemedel och finansiell information. Tillgången till Darknet kan vara anonym genom att använda TOR och Bitcoin. Anonymiteten vid webbsökning under användandet av Darknet kommer påverka bevis för myndigheter. Således kan det ha en möjlig effekt på brottsbekämpande arbete, särskilt angående digitalt kriminaltekniskt arbete, utifrån begränsningen av tillgängliga data. Således syftar denna studie till att fastställa vad de svenska myndigheterna arbetar med för att stoppa illegala aktiviteter som utförs med hjälp av Darknet, i samband med begränsningarna från svensk lagstiftning. Studien kommer att genomföras med hjälp av intervjuer med polis, advokat, köpare och tullen för att få deras insikt och åsikt om det valda ämnet. Medan statistiska uppgifter kommer från undersökningar med kunniga respondenter från forum. På grund av detta kan arbetet fungera som en väsentlig förståelse för hur Darknet kan påverka nutiden och framtida brottsutredningar. Ytterligare arbete måste utföras i området för att lösa potentiella implikationer, eftersom detta arbete endast examinerar om det finns påverkan / Darknet is a part of the Deep web, which an unindexed section of the internet. It is in use forvarious purposes, e.g., buying drugs and financial information. The access to Darknet can besubstantially anonymous by using TOR and bitcoin. Given anonymity for web browsing, it will directly impact evidence about illicit purchases. So, itmay have a possible effect on law enforcement work, particularly on digital forensic work due tothe limitation of data available. Thus, this study aims to determine what the Swedish government isdoing to stop Darknet trading, along with the limitations from Swedish regulations. The focus is thus on criminal prosecution and criminal investigation. The study will be throughconducting interviews with police, lawyer, buyer, and border control to get et their insight andopinion on the chosen topic. Statistical data is from conducting surveys with knowledgeablerespondents from forums. Due to this, the work can serve as an essential understanding of how Darknet may impact presentand future criminal investigations. Additional work must be done in the area to solve the potentialimplications, due to this work only examines if there are any impacts
