Sorry for the long title.
It was years ago when legal highs were steadily become more available.
A new legal high will be made illegal, then the composition can be changed very slightly which makes it legal again.
A few friends, presumably scientists of some kind did this, I think there was 4 of them.
They took the new drug they created and they all ended up in a wheelchair unable to control their limbs or talk.
It was brutal, and I always remember thinking that I want to show my some when he becomes old enough that he might dabble, to show how dangerous it is to try 'legal' highs.
Now I can't find anything about it no matter what I search for.
Does anyone else know what I'm talking about?
