Professor David Albert Jones:

If the committee is interested, I can give evidence on this. People I know in palliative care often get quite agitated about this. It is a common example that people give for double effect, but it is not actually good practice with regard to palliative care. It need not shorten life. In getting the same amount of adequate symptom relief, one can get as good or better symptom relief from opiates with no shortening of life.
