Addiction relapse driven by drug-seeking habit, not just drug
Why are some individuals able to use recreational drugs in a controlled way, whereas others switch to the compulsive, relapsing drug-seeking and -taking habits that characterize substance use disorder (SUD)? Despite more than six decades of extensive research, the question remains unanswered, hampering the development of targeted prevention and therapeutic strategies. Now, a new study in rats identifies the maladaptive nature of drug-seeking habits and how they contribute to the perpetuation of addiction by promoting the tendency to relapse.
