Burenorphine is widely prescribed in France  used to be THE substitute drug but isn’t any longer in France. Instead som 50.000 opiate addicts use Buprenorphine in France at the moment. Experiments with the drug are also being carried out in Sweden. CSAT( USA)  is  proposing regulatory changes to make buprenorphine more accessible for the treatment of addicts. Unlike  methadone, it is a fairly mild narcotic that should block craving while  having negligible effects. One proposed preparation will mix this with  naloxone which is a narcotic antagonist and which is used to reverse the effects of narcotics abruptly in overdose situations. If the pill is crushed, the Naloxone would be activated.
