Giving a 10 day supply prevents individuals from having to make another appointment and pay for another office visit. I would bet every police/fire station or hospital in the country has a drug amnesty box where people can take their unused eds. Sometimes we have to be responsible for our own actions...including properly disposing of unused medications.
Opiate addiction is more and more treated on an outpatient basis. Unless there is a comorbid diagnosis (usually Major Depressive D/O) and an expressed risk of harm to self or others, day treatment and outpatient is becoming the standard. Extreme cases may require a 72 hour detox (whihc is approx the same for alcoholics). Its still nasty stuff...not minimizing it. And we can al agree...meds are over-prescribed. ALL meds. But I think its bigger than just pharm and lazy docs. Leaving out the corrupt pill peddlers that are a real problem, the best solution is maybe for patients and docs to work together on a treatment plan that minimizes opioid use.
