Emma Best, who chairs the committee, said access to the medicines is currently “deeply unequal”.
“While thousands of people are able to buy these treatments privately, only a tiny fraction are receiving them on the NHS.
“We heard powerful evidence from Londoners whose health and confidence have improved because of these medicines – but we also heard real concerns about people being pushed towards unsafe or counterfeit products when they cannot access proper treatment.”
The committee said patients were acquiring the medicines in beauty salons, gyms, and on social media, and in other cases, in pubs and fish and chip shops.
“If these drugs are going to play a meaningful role in improving London’s health, the NHS rollout must move faster…and regulators must crack down on the growing illegal market, the report recommended.
An NHSE London spokesperson said: We will closely monitor prescribing data and referrals to behavioural support to ensure uptake is equitable, addresses current inequalities of access, and supports sustained behaviour change.
“We are committed to ensuring that every eligible Londoner, regardless of where they live or their financial means, can access these medicines safely and with the right support around them.”
