Key Aspects of Successful Rehabilitation After Repeated or Serious Driving Offenses

In Germany, license restoration after serious or repeated offenses requires a positive Medical Psychological Assessment (MPA), a test to determine the driver's aptitude. Fulfilling the conditions necessary for a positive MPA often takes longer than the period of license revocation, which is perhaps due to the involvement of different personal, organizational, and environmental factors. To optimize the rehabilitation process, the present study analyzed the key aspects of successful rehabilitation after repeated or serious driving offenses.

After participating in the MPA, 1,631 subjects completed a questionnaire about rehabilitation efforts in order to regain their driver aptitude. The selection of items for this questionnaire was made according to our own prior research, interviews with problem drivers, and the diagnostic criteria for the MPA. Participants were asked when and from whom they obtained certain information, and how relevant this information was for their success. In contrast to other studies, which used re-offense rates as a criterion for successful rehabilitation, we used a positive MPA result (positive, negative, or training) as the criterion for success. 
  • Just over half (52%) of the participants considered themselves optimally informed about the rehabilitation process. 
  • The others (47.4% of participants) judged the adequacy of received information as less than satisfactory. 
  • Offenders who did not partake in counseling before the MPA achieved a successful result only about half as often (37.1%) as those who did (70%), 
  • and were around three times as likely to have additional courses imposed upon them (21% vs. 7.6%). 
  • Of the offenders who received crucial and helpful information at an early stage, 62.4% attained a positive MPA at the first attempt (regardless of having attended any training courses). 
The success rate for the first attempt rose to 81% for offenders who were well informed at an early stage and participated in counseling before their first MPA.

The results clearly indicate that the provision of relevant information at an early stage combined with counseling has a beneficial influence on success rates for the rehabilitation process (an increase from 37.1% to 81%). As such, we recommend the introduction of obligatory license consultations, offered by MPA experts, involving a status assessment to customize offenders' rehabilitation and thereby provide more or less intensive guidance or coaching depending on offenders' characteristics throughout their progression through the MPA system.

Cannabinoids in Exhaled Breath Following Controlled Administration of Smoked Marijuana

Below:  Median (interquartile range) THC breath concentrations from chronic and occasional cannabinoid smokers after smoking a single 6.8% THC cigarette for 10 min
Dashed line indicates limit of quantitation. *P = 0.0156, group comparison.

THC was the major cannabinoid in breath; no sample contained THCCOOH and only 1 contained CBN. Among chronic smokers (n = 13), all breath samples were positive for THC at 0.89 h, 76.9% at 1.38 h, and 53.8% at 2.38 h, and only 1 sample was positive at 4.2 h after smoking. Among occasional smokers (n = 11), 90.9% of breath samples were THC-positive at 0.95 h and 63.6% at 1.49 h. One occasional smoker had no detectable THC. Analyte recovery from breath pads by methanolic extraction was 84.2%–97.4%. Limits of quantification were 50 pg/pad for THC and CBN and 100 pg/pad for THCCOOH. Solid-phase extraction efficiency was 46.6%–52.1% (THC) and 76.3%–83.8% (THCCOOH, CBN). Matrix effects were −34.6% to 12.3%. Cannabinoids fortified onto breath pads were stable (≤18.2% concentration change) for 8 h at room temperature and −20°C storage for 6 months.

Breath may offer an alternative matrix for testing for recent driving under the influence of cannabis, but is limited to a short detection window (0.5–2 h).

Patterns of Alcohol Consumption and Related Behaviors in Brazil: Evidence from the 2013 National Health Survey (PNS 2013)

Below:  State-level prevalence rates of selected drinking behaviors among adults aged 18 and above, Brazil 2013.
Data source: PNS 2013, public use Arc-GIS shape files; authors’ calculations. Results include sample weights and control for survey design. Current drinkers defined as reporting having at least 1 drink in the past 30 days. Rates for drinking and driving are among current drinkers who also drive a car or motorcycle. Binge drinking defined as at least 5 (for men) or 4 (for women) drinks in one occasion among current drinkers. Frequent binge drinking defined as 4 or more episodes in the past 30 days, among binge drinkers.


Below:  Probability of drinking and driving by report of binge drinking, sex, and age.
Data source: PNS 2013, authors’ calculations. Results are predicted probabilities of self-reported drinking and driving, controlling for age, sex, educational attainment, rural and capital city residence, skin color, martial status, drinking before age 18, binge drinking, and interactions between age, sex, and binge drinking.


This study uses data from a nationally representative household survey (the 2013 National Health Survey, n = 62,986) to describe patterns of alcohol consumption and related behaviors among Brazilian adults. Analyses include descriptive and multivariable Poisson regression for self-reports in the past 30 days of: drinking any alcohol, binge drinking, binge drinking 4 or more times, and driving after drinking (DD); as well as age of alcohol consumption initiation. Results show that current drinking prevalence was 26%, with an average age of initiation of 18.7 years. Binge drinking was reported by 51% of drinkers, 43% of whom reported binge drinking 4 or more times. Drinking and driving was reported by nearly one quarter of those who drive a car/motorcycle. Current drinking was more likely among males, ages 25–34, single, urban, and those with more education. Binge drinking was more likely among males, older age groups, and people who started drinking before 18. Drinking and driving was higher among males, those with more education, and rural residents. Those who binge-drink were nearly 70% more likely to report DD. All behaviors varied significantly among Brazilian states. Given their potential health consequences, the levels of injurious alcohol behaviors observed here warrant increased attention from Brazilian policymakers and civil society.
