The main problem with the panorama program was this -
He presented to the private clinics undercover. He reckons he filled in their screeners all accurately - but the screeners are around 95% accurate at pinpointing ADHD.
NHS waiting lists in most places are 2-5 years long. They didn't pick a presenter who happened to be on one already - they must have phoned up and said "We're doing a documentary for the BBC, can you show us what the diagnostic process would be like please?" The NHS psychiatrist knew that he didn't think he had ADHD.
That's not the same thing. It's completely biased. And since we already know that psychiatrists are prone to bias, this shouldn't be much of a surprise. When people go for an ADHD assessment, they aren't generally just going to say "Oh I read some memes on tiktok, sounds interesting, now I'm curious if I have this thing or not?" - they are going because they are severely struggling in life and want to know what might be the root cause and what could help. It might not be ADHD, but autism, depression, PTSD, thyroid issues, vitamin deficiency, coeliac disease etc. A good assessment process should be ruling other things out, and it's not uncommon for women especially with ADHD to have previously been diagnosed with anxiety and/or depression.
This disorder wrecks relationships and leads to people being fired from jobs and can prevent you getting a job or completing education. Most people don't have 2-5 years to just throw away once they know what could potentially help them. Of course, most people don't have any other option.
Oh, and it's not like it's an instant cure - you have to find the right medication which takes ages, unlearn all your crap unhelpful coping strategies which you've relied on for years, then learn new systems, potentially while dealing with the fallout of the untreated ADHD and/or the shitty coping strategies. It takes most people a good year or two after diagnosis to get things straightened out.
There could have been a really good documentary about why waiting lists are so long, why suddenly so many people are seeking diagnosis which is overwhelming the NHS capacity, why people are seeking private assessment and whether people getting private assessments over RTC are being short changed or whether telehealth is appropriate for this kind of thing.
Instead it was "ADHD is just a made up excuse for laziness and a reason to get free drugs!"
It's probably easier and cheaper to buy drugs illegally (if that is what you want) than it is to get hold of a prescription for extremely weak speed which BTW is adjusted so it can only be processed in the gut, for the most common form prescribed, which means it's not abusable and won't get you high.
