I’d read about a drug called naltrexone, which is a pill that helps mitigate and manage alcohol cravings and abuse.

It also provides drugs like buprenorphine and naltrexone, medications used to treat opioid dependency, as well as naloxone rescue kits for overdoses.

But once the opioid-dependent people received a drug called naltrexone, which blocks the effects of opioids, their brains produced a more normal response.
