Drug testing Types of tests A drug test is a test to find out if you have used a drug or drugs. They look for very small amounts of drugs in the body.

Illegal Drug Use and Crime: A Complex Relationship

There are different types of drug tests: This form of testing is used in random roadside drug testing. A roadside saliva screening test takes around five minutes. Where a positive result is obtained, the driver is required to undertake a second saliva test or provide a blood sample to confirm the presence of the prescribed drug. In most cases, the confirmatory saliva test takes around 30 minutes. Blood tests Blood testing is often used to test for recent drug use e. This form of testing is not widely used as it is quite expensive.

Urine tests Urine testing is the most common method of testing as it detects drug use for a longer period of time longer than blood, but not as long as hair tests and it is easier to administer and is more accurate. Urine drug tests are commonly used in workplace drug testing, and usually give accurate results. If you are asked to have a urine test, you will be asked to urinate pee into a container and your urine will be tested using a dipstick. Hair tests Hair testing can provide a history of drug use as traces of drugs may accumulate in your hair.

The length of the hair can determine how far back drugs may be traced back. It is the only reliable method that can be used to detect drug use beyond a couple of days or weeks. These studies should exhibit none of the common methodological deficiencies, seek to minimize all challenges to validity, and examine the full spectrum of drug activities and other criminal behavior. The present study is an attempt to fill a small part of the gap. The primacy in criminological and social research of the impact of drugs on violent activity provides a useful point of departure.

The literature is far from agreement on the nature of this relationship and even on its existence. In other words, because of weaknesses in research design, we cannot be certain that drug activity is a sufficient condition of violence. It is therefore the intention of the current study to present a research design more conducive to permitting causal inference. A robust data set will be employed to analyze the contribution of drug use and drug selling to violent behavior among a longitudinal panel of high-risk youth.

As will be elaborated below, the robustness of the data allows the present study to avoid devotion to single-cause descriptions as well as to account for an extensive variety of correlates and precursors. The longitudinal nature of the data allows for exanimation of the relationship through time. The panel is representative to a general population, rather than being applicable to only incarcerated or institutionalized persons.

Finally, because the data contain information gathered from multiple sources including the participants, parents and guardians, schools, and policethe current study is not reliant solely on official data and can thus remove the bias such reliance creates.

No singular empirical study will be capable of resolving all the issues surrounding research in drugs and violence, and it is not suggested that this study will provide the final word on the matter. Rather, it is hoped the current study will be one of many to move us closer to being able to assess causality between drug offending and violent crime.

Method Data Data for the current study are drawn from the RYDS, an ongoing longitudinal study of a panel of youth at high risk for violence and delinquency. To date, RYDS has completed 14 waves of interviews for the panel, reaching participants ages in the early 30s. Data are drawn from Wave 4 through Wave 9, when respondents were between the ages of 14 and First, prior to Wave 4, the questions regarding delinquent offending were not consistent.

Second, in the first three waves, the RYDS participants showed very little variation on the measures of delinquency, particularly violence. The original RYDS sample was stratified on two dimensions to select participants who were at high risk for violence and delinquency. This was based on the assumption that adolescents who live in such areas are at greater risk for offending than students living in areas with lower residential arrest rates.

These proportions are quite close to what was expected given the population characteristics of Rochester schools and the decision to oversample high-risk youth. Participant attrition in the RYDS is quite low when compared with other longitudinal studies. Measures In the delinquent offending section of the RYDS interview, the participants were asked about their participation in a wide variety of delinquent and violent activities since the date of the last interview that is, within the last 6 months.

If the participant indicated he or she had committed the offense, the participant was then asked to report how many times he or she had done so. This pattern of questions was consistent from Waves 4 to 9. These questions were used in the creation of the central dependent and independent variables in this study. This section asked participants about six individual violent offenses. These offenses were as follows: Between Waves 4 and 9, no participant reported ever engaging in this final offense.

Therefore, five violent offenses exhibit some level of variation and are used in creating measures for this study. Several measures of violence incidence were created.

The first such measure is a count of the total number of violent offenses a participant committed during a specific wave. This measure is identical to the first violent offense count measure, except that it does not include the offenses of hitting someone to hurt them or throwing an object at people.

Furthermore, the study includes a count of the number of times a participant committed each of the five offenses at a specific wave. Each of these incidence measures has a parallel prevalence measure as well. That is, the study uses a measure that indicates whether or not the participant ever committed violence, serious violence, or a particular violent offense i. The incidence and prevalence measures of violent offending collectively make up the set of dependent variables used in subsequent analyses.

In addition to the violent offenses mentioned above, the delinquency portion of the interview also asked participants to report their drug offenses. The participants were also asked whether, since the date of the last interview, they had sold drugs, and if so, which drugs and how many times.

From these questions were created the two key independent variables: In other words, a participant is treated as a gang member if he or she reports being one.

This measure has been used and validated in previous research notably, Thornberry et al. Analysis The analytic strategy used in this study is shaped by the goal of making substantial improvements to the common methodological deficiencies of drugs and crime research detailed above. The representative RYDS sample and the longitudinal nature of the project allow the current study to overcome two such deficiencies: The measures used herein are created from self-reported items, and thus the study does not rely on official data.

To assess the impact of drug use and drug selling on adolescent violent behaviors, the following structural model is used: It is important to simultaneously include Uit and Sit because drug use and drug selling are markedly different activities, with many individuals engaging in one but not the other. The correlation coefficient between drug use and drug selling in the current sample is only moderate, at. As mentioned above, the level of drug selling by RYDS participants while in a gang is quite high see Thornberry et al.

In other words, drug selling and gang membership may each have main effects, but there may also be an interaction effect.

Two sets of models are estimated with the data, which impose varying assumptions regarding the time-stable unobservables. The individual effect is assumed to be drawn randomly from a normal distribution with a mean of 0 and whose standard deviation is estimated by the model. This assumption makes random-effects estimates statistically efficient.

In random-effects models, the individual effect is assumed to be independent of the regressors. In this case, that means the individual effect is assumed to be uncorrelated with drug use and drug selling. When this assumption is violated, the estimates are biased and inefficient. The second set of models are fixed-effects models. In these models, individual-specific means for variables are subtracted from the value at each time period.

In effect, fixed-effects models control for the individual effect by removing it, even though it is unmeasured or unobserved. Compared with random-effects models, fixed-effects models are less contingent on the assumption that the individual effect is uncorrelated with the regressors although they are not completely free from this assumption either. A chief concern with fixed-effects models is that because they remove the individual effect, they cannot provide estimates for time-stable individual variables, even when measured.

However, that also means fixed-effects models cannot provide an estimate for the regressors of interest, namely, drug use and drug selling, if these never change for an individual. We can see that the two models offer advantages and disadvantages. But, both models are able to control for population heterogeneity and empirical correlates of drug use and criminality.

In this way, the present study is able to improve on prior research. Furthermore, by simultaneously including measures of drug use and drug selling in the model, estimates are generated that assess the impact of one behavior on violent offending net of the influence of the other. In other words, covariation between drug use and drug selling is held constant.
