Objective measures of pain processing, e.g. encephalography (EEG) and quantitative sensory testing (QST), are included to provide insight in underlying nociceptive processing.', 'detailedDescription': 'The most important symptom in chronic pancreatitis (CP) is abdominal pain. Pancreatic pain is often recurrent, intense and long-lasting, and is extremely difficult to treat. Medical analgesic therapy is considered as first choice in pain management of CP, resulting in regularly prescription of opioids. The adverse consequences of prolonged opioid use, including addiction, tolerance and opioid induced hyperalgesia, call for an alternative medical treatment. Cannabis has been used to treat pain for many centuries. Delta-9-tetrahydrocannabinol (Δ9-THC), the psychoactive substance of the cannabis plant, has been shown in previous studies to be a promising analgesic. The development of Namisol®, a tablet containing purified Δ9-THC showing an improved and reliable pharmacokinetic profile, provides the opportunity to test the analgesic potential of Δ9-THC in favourable conditions.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Patient has chronic pancreatitis, diagnosed using the Marseille and Cambridge Classification System (addendum II).37\n* Patient suffers from chronic abdominal pain typical for pancreatitis, meet the criteria for chronic pain according ISAP (intermittent or persistent pain on a daily basis in at least 3 months)38, and consider their pain must as severe enough for medical treatment (average NRS ≥ 3).\n* Patient in the opioid group takes stable doses of opioids, e.g. morphine or tramadol, for the past 2 months on the day of screening.
