A widely used preclinical procedure to study features of cocaine addiction involves allowing laboratory animals to take drug continuously, for hours each day. However, data in human cocaine users suggest that cocaine use may typically be intermittent, rather than continuous. Here I will present surprising findings concerning the effects of intermittent versus continuous cocaine intake in rats. As it turns out, less is more, and intermittent cocaine use is especially effective in producing addiction-relevant patterns of cocaine seeking and taking.
