In their Seminar on mild cognitive impairment,1 Serge Gauthier and colleagues list useful tools for the prevention of cognitive decline. Identification of mutable factors in the early stages of cognitive decline can be critical to effective prevention. In this setting, increasing evidence suggests that insulin concentrations could have a direct effect on cognitive function.2–4 Furthermore, cognitive impairment with clinical features indicative of subcortical damage has been shown to be associated with insulin resistance.5 Therefore, interventions aimed at early diagnosis and treatment of abnormal glucose metabolism should be added to Gauthier and colleagues’ prevention tools. We declare that we have no conflict of interest.

is starting a programme of research into the neurophysiological effects of lysergic acid diethylamide (LSD) and other compounds to discover whether, or how, they might be used as an adjunct to psychotherapy. Unfortunately, since I have been told that we would not get ethics approval in the UK, we have been forced to pursue the research elsewhere. This is a great pity because we understand that, were ethics permission granted, several UK research groups are extremely able and willing to do this important work. I declare that I have no conflict of interest.

I would like to endorse The Lancet’s comments about the need to revive research into psychedelic drugs (April 15, p 1214).1 I am the director of the Beckley Foundation, a charitable trust that
his or her religious or moral beliefs, it does require pharmacists to respect patients’ decisions and beliefs and to advise them of other ways that they can access the required service to ensure that their care is not unduly compromised. If a pharmacist’s beliefs or personal convictions prevent him or her from providing a particular service, the pharmacist must disclose this fact before accepting employment to allow procedures to be put in place to enable patients to access the services they require. In such circumstances the Code of Ethics and Standards requires that a pharmacist must not condemn or criticise the patient and that either the pharmacist or a member of staff must advise the patient of an alternative source for the service requested.
Royal Pharmaceutical Society and conscientious objectors In her Comment (April 15, p 1219),1 Katrina Bramstedt highlights conscientious objection by US pharmacists to the prescription of emergency contraception. Readers might be interested to learn the position with regard to pharmacists working in Great Britain who might have similar objections. The Royal Pharmaceutical Society is the regulatory and professional body for pharmacists in Great Britain. Our Code of Ethics and Standards requires that pharmacists act in the interests of patients and the public. However, as with other regulators of health-care professionals, the Society recognises that a pharmacist’s beliefs or personal convictions might prevent him or her from providing a particular professional service (for example the supply of emergency hormonal contraception). Although the Code does not compel a pharmacist to provide a service that is contrary to
