There is an episode of BBC Horizon with the title Cannabis: Miracle Medicine or Dangerous Drug?, presented by Dr Javid Abdelmoneim.

At mins 16:40 the presenter shows a youtube video of a person affected by Parkinson's visibly shaking, smoking a joint and then showing that the joint reduced the tremor. Then the doctors states that the video might be genuine, but that it does not give enough evidence that cannabis can cure Parkinson's.

I am wondering whether he put it too mildly, because the video might be a fake. While the man was holding the joint he was not shaking as much as he did in the first sequence. But that is before the joint could have an effect, why the tremor was milder in that sequence? What happened in the sequences that were not included in the documentary?

Showing the claim and simply stating that there is not enough evidence is already enough to create false expectations in at least part of the viewers. A lot of people have been tricked by vague claims not properly debunked. Therefore I would like to know whether there are elements to understand whether the video is a fake or not.

If the video turned out to be a fake there would be side question, can a doctor be tricked into thinking that the video might be genuine?

Update: I repeat that the main question here is whether the video shown in the documentary is staged or not. Not whether cannabis can cure Parkinson's.

    I started to edit this, but realised that there is no notable claim here. Abdelmoneim says there is NOT sufficient evidence. If you want to ask the question, find people who DO believe, but there is little point because you know the answer (as of 2019) - Abdelmoneim gave a reference.

  • Unless your real question is "Is this particular anecdotal video fake?" in which case link to the video, and ask that. [Hint: Parkinson's symptoms are heavily affected by placebo, which is why Abdelmoneim looks for scientific evidence.]

  • @Oddthinking I did not link the video because I do not have a link to the video. I just got the impression that what I saw in the documentary was phoney.

  • The point of the sequence is to show the video as an example of the things viewers might be seeing on the internet, and then have a doctor say that such videos don't constitute good evidence for cannabis as a miracle medicine. Commented Feb 27, 2023 at 15:01

Ian Frizell is a YouTuber and advocate for medicinal cannabis. He has early-onset Parkinson's Disease.

The video shown on the screen in the documentary is his: Revised Parkinson's Disease Tremor Control. (There is also a short snippet of a more recent video).

It is difficult to demonstrate a video is not fake. Most of my arguments are rather indirect:

In summary, I can't demonstrate that the video is not fake, but I can offer circumstantial evidence that it isn't, as well as reasons why it doesn't matter (clinically) if it is, and it doesn't matter (clinically) if it isn't.
