AB  - Voucher-based reinforcement therapy (VBRT) is an efficacious contingency 
      management intervention for substance use disorders that provides escalating 
      voucher values to reinforce continuous abstinence and typically resets escalated 
      values to the initial low level upon detection of drug use. The objective of this 
      study involving 130 methadone-maintained outpatients receiving VBRT was to 
      investigate whether resets (a) increase risk for adverse events (AEs) and (b) 
      delay return to abstinence in relation to magnitude of voucher reset. Weeks 
      following resets were examined for increased likelihood of AEs using a Poisson 
      regression. A Cox proportional hazards model was used to determine if higher 
      resets increased the number of days until a negative urine specimen. Results 
      showed that resets did not increase the likelihood of AEs nor were higher resets 
      related to an increased delay to abstinence. Research involving larger samples is 
      needed to produce sufficient data directly addressing safety concerns of various 
      treatment stakeholders.
