Gemma May Weeks · Prevention of Future Deaths report

On the 27th January 2025, an investigation was commenced into the death of Gemma May Weeks, born on the 13th November 1996.

The investigation concluded at the end of the Inquest on the 6th August 2025.

The Medical Cause of Death was:

1a Combined drug toxicity (ketamine and ████████)
1b
1c
2 Urinary bladder necrosis and chronic pyelonephritis due to ketamine

The conclusion of the Inquest recorded that Gemma May Weeks’ death was drug related.

Miss Weeks had been a ketamine user for approximately 10 years. Her use of ketamine, a controlled drug of class B, had increased over the years and there are reports that in 2024 she was using approximately £500 of ketamine per week. Long term use of ketamine had had a detrimental effect on Miss Weeks’ health. She was significantly underweight (ketamine suppresses the appetite) and had developed ketamine bladder syndrome, a condition associated with considerable pain and incontinence. Despite the health complications caused by the regular ketamine use, Miss Weeks was unable, even with considerable support, to achieve a sustained period of abstinence. She reported that the pain caused by the damage to her bladder could only be relieved by the analgesic properties of ketamine, thereby leading to further and increased use, causing further bladder damage. On 26th January 2025 she was found deceased in her room at her temporary accommodation. She had consumed high levels of ketamine and ████████, the combined effects of which caused her death.

1. During the inquest evidence was heard that:

i. Ketamine is a controlled drug of class B. There is a perception in naïve users that this signifies “lesser” risks associated with using ketamine as compared with class A drugs. However, in acute overdose, ketamine can be fatal. It is also highly addictive, with reports of usage notably increasing in young people, among whom the risks of ketamine use do not appear to be well understood. I heard evidence that ketamine has become easily, widely and cheaply available. Local drug treatment agencies have seen a corresponding increase in individuals reporting ketamine addiction and seeking assistance for the same. In addition, chronic ketamine use can lead to devastating health complications, including ketamine bladder syndrome, an extremely painful condition that requires reconstructive surgery to repair.

2. I have concerns with regard to the following:

i. The dangers and risk associated with both acute and chronic ketamine use are not well understood by the public and potential first time users of the drug. Ketamine’s classification as a class B controlled drug may give an impression that the dangers associated with its use are reduced as compared with class A drugs.

ii. There is little understanding of the risks and dangers of ketamine use amongst the age group that appear to be at most risk of starting to use the drug.

iii. The health consequences of chronic ketamine use are well understood by those that encounter them, including drug treatment providers and those working in healthcare. Those consequences are not, however, well understood outside of those circles.
