Forgot to add that I am feeling a little more mellow having recently been releaased from hospital, where, to control pain I have been prescribed morphine. I have had no side effects (nausea, constipation, drousiness etc) whatever and as a drug it is very effective. I am not sure of the addictive quality of morphine having only been taking it for 6 weeks, but the dose has had to be increased as my tolerance to it built up.
As a drug (morphine) that is effective and understood by medical and nursing staff. I wonder (assuming that M6g is licenced) if the benefits of reduced side effects will be sufficient to repay the investment that trials and research will have cost the shareholders of CEN.
