Freedom of Religion
Health and Medicine
In 2003 Mr Simpson proposed EDM 643: Society of Homeopaths, which congratulated the Society of Homeopaths on its 25th anniversary and recognised "the crucial role professional homeopaths can play in reducing the burden on GPs at primary care level".
Following the publication of the House of Commons' Science and Technology Committee's report "Evidence Check 2: Homeopathy" in February 2010, Simpson seconded Early Day Motion 908: Science and Technology Committee Report on Homeopathy, which was critical of the report.
Alan Simpson has signed a number of Early Day Motions that support the use of herbal medicines.

Alan Simpson was one of 79 MPs who signed Early Day Motion 377 noting the achievements of Charles Darwin, and calling for Darwin's birthday to be designated a public holiday to honour "one of the fathers of modern science and one of Britain's greatest, if not the greatest, scientific minds."
Policymaking On Drugs And Alcohol
Alan Simpson signed Early Day Motion 2244 calling for Government policy on alcohol and drugs misuse and harm to be based on scientific evidence. The motion came shortly after the sacking of Government drug adviser David Nutt by Home Secretary Alan Johnson in 2009.
Libel Law Reform
In January 2010, Alan Simpson signed Early Day Motion 423 calling for a reform of the English libel law. The motion noted that human rights activists, scientists, writers and journalists are currently prevented from publishing, and the public prevented from reading, matters of strong public interest due to the chilling effect of the law.
In January 2010, Alan Simpson signed Early Day Motion 524: Recognising Climate Change which states that "this House agrees that climate change is happening and is man-made" and calls this statement a "fact, which has the support of the overwhelming majority of the scientific community".
