"The drug or cult has major if not exclusive sources of brain rewards"

This quote by Keith Henson recommends that drugs or cults can have an effective impact on the brain. He indicates that these compounds or activities can provide a person with a sense of benefit or pleasure that is tough to find in other places. This reward can be so strong that it becomes the main source of enjoyment for the individual. Henson is recommending that these substances or activities can be so powerful that they end up being the main source of satisfaction for an individual, and that other sources of pleasure end up being secondary or even non-existent. This can be unsafe, as it can lead to addiction or an unhealthy fixation with the drug or cult. It is essential to be aware of the potential threats associated with these substances or activities, and to ensure that they are not the only source of pleasure in an individual's life.
