The Angelus Foundation was founded in 2009 by Maryon Stewart, the health practitioner, author and broadcaster. Her 21 year-old daughter Hester (pictured), a medical student and athlete, passed away after consuming a legal high (GBL) in April 2009. The Foundation has since attracted a group of experts, which make up the Angelus Advisory Board. They bring together expertise from chemical, medical and behavioural sciences, as well as having considerable knowledge and experience in the areas of enforcement and misuse of substances.

Our Mission Statement

To help society understand the dangers of ‘legal highs’ (new psychoactive substances), to reduce the harm they cause to young people and their families, and to save lives.

Our Aims and Objectives

We aim to become the acknowledged expert and knowledge centre on the subject of the dangers of legal highs and to maximise public understanding of the risks.

The Foundation’s work

We have embarked on various projects which:

scope the problem

raise awareness of legal highs

educate about the risk of these substances

aim to make the use of party drugs less socially acceptable

enable parents to have informed conversations with their children on the use of legal highs

empower young people to make more responsible lifestyle choices

improve the understanding of the physiological and psychological impact of these substances on the human body and mind


Angelus Foundation is committed to help raise awareness about the dangers of legal highs and party drugs and now have a group of  experts to advise on its work programme. We now know that simply adding substances to the list of controlled drugs is not the solution: each time something is banned the chemists just tweak the molecules and put something else on the market.

We have been lobbying Ministers for Education, Health and Home Office and liaising with Senior Civil Servants. The issues are urgent and need addressing in a co-ordinated manner by all political parties.
