Differences in the frequency and severity of adverse effects between the two arms.The participant will be visited at home weekly and phoned weekly at times convenient to the patient, visits will last approximately 30-40 minutes. their blood pressure, heart rate and respiratory rate will be measured, their blood oxygen saturation by means of a pulse oximeter and their end tidal cardon dioxide by means of an end tidal carbon dioxide monitor.
Using the Anticipated Adverse Event Assessment frequent side effects of morphine sulphate will be monitored and categorised according to the National Cancer Institute Common Toxicity Criteria for Adverse Events.This will be assessed at both the home and phone contacts.
Adverse events will also be monitored by asking the patient if they have "any other problems" and how they rate the effectiveness of breathlessness control, both assessed twice weekly.They are asked to fill out the Chronic Respiratiory Questionnaire - Dyspnoea Subscale (Mcmaster University) weekly.

Profile of the descriptive type(s) of the subjective sensation of dyspnoea that are more likely to be associated with mesothelioma, asbestosis or interstitial lung disease.
Participant will keep a diary for a maximum of 23 days, anticipated to take 5-10 minutes daily to fill out. They will be asked to indicate twice daily,the intensity of dyspnoea now on a modified Borg scale, the intensity and separately the unpleasantness of dyspnoea now, on a Visual Analogue Scale (VAS) and the intensity and unpleasantness of breathlessness on a four point catagorical score. To indicate once daily, their average breathlessness, worst breathlessness and best breathlessness in in the last 24 hours, each utilising a VAS scale and their exercise tolerance using the Medical Research Council of Great Britain Scale for Dyspnoea.
They will also be asked to indicate twice in their diary,at the end of each arm, (active and control) the level of dyspnoea control and the overall level of dyspnoea in the last 7 days and the level of satisfaction with medications received in the last 7 days.
(While measurements and analysis will be based upon the data from the last 3 days of each arm participants are also asked to provide responses once or twice daily to make sure they are comfortable with the pattern of participation prior to responding on the key census days).

Summary
Brief summary
This study aims to determine whether morphine reduces the feeling of breathlessness in patients with mesothelioma, asbestosis or interstitial lung disease.
Who is it for?
you can join this study if you are 18 years or more, and suffer from a feeling of breathlessness (dyspnoea) as a result of maximally treated mesothelioma, asbestosis, or interstitial lung disease. You must be able to speak English and should not be taking regular opioid medication (painkillers).
Trial details
Participants in this trial will be randomly (by chance) assigned to receive either 20mg sustained-release morphine (by oral capsule) together with a laxitive Coloxyl and Senna, or placebo (sham) tablets for one week. They will receive no medication for the second week and will then receive the alternate treatment ( morphine or placebo) for the third week. Participants will not know when they are taking the active drug or placebo.
Participants will be asked to complete questionnaires and keep a diary over the 3 weeks of the trial to determine their response to treatment. They will also be phoned and visited at home by a nurse to monitor any side effects of treatment.
