If digital drugs or binaural beats mean sounds that are thought to be capable of changing brain wave patterns and inducing an altered state of consciousness similar to that effected by taking drugs or achieving a deep state of meditation., then there are notions on their effect on pain: Experts Examine Future Options in Digital Drugs for Pain Released: 13-Jun-2013 3:00 AM EDT

While this is a relative new aspect of adolescent health to me, we certainly see that exposure to a specific (yet ambiguous, arguably) sound can have largely unexplored influences on the mind. Chraif (2012) demonstrated this on simple task performance, so speaking beyond these results is a reach, who is a scientist who doesn't reach? I would argue that we have evidence to suggest the mind is influenced in unknown ways by sound, therefore the potential exists these influences may lead to the experience of an "altered state." Obviously from this position we cannot know the health consequences of such an experience, but we have a starting point.
