Study highlights new and cheaper way to treat heroin addiction

... ?dihydrocodeine is much easier to store and comes under less stringent regulations because it is not as toxic and less likely to cause a fatal overdose. It is estimated that whereas methadone treatment can cost almost £1,500 annually per patient, the cost of dihydrocodeine is £713. Dihydrocodeine has b...
