Definition |

| | rehabilitate | Helping a person recover from drug addiction. Rehabilitation teaches the addict new behaviors to live life without drugs. |
| | relapse | In general, to fall back to a former condition. Here, resuming the use of a drug one has tried to stop using. Relapse is a common occurrence in many chronic disorders that require behavioral adjustments to treat effectively. |
| | respiratory center | A small set of nuclei in the brain stem that regulate the speed and depth of breathing ultimately by controlling the muscles that move our chest and diaphragm. |
| | reuptake | The process by which neurotransmitters are removed from the synapse by being "pumped" back into the axon terminals that first released them. |
| | reuptake pump | The large molecule that actually transports neurotransmitter molecules back into the axon terminals that released them. |
| | reward | The process that reinforces behavior. It is mediated at least in part by the release of dopamine into the nucleus accumbens. Human subjects report that reward is associated with feelings of pleasure. |
| | route of administration | The way a drug is put into the body. Eating, drinking, inhaling, injecting, snorting, smoking, and absorbing a drug through mucous membranes all are routes of administration used to consume drugs of abuse. |
