Truth isn’t different between serious and casual discussion and this is a serious topic.

If you want to cite a scientific paper then do it yourself and don’t ask others to fish them out of blogs you link to because too many times I’ve seen none included and nobody got time for that on a casual forum.

As to actual sources, I assumed I wouldn’t have to make as much of a strong point when talking about something that’s pretty much a scientific consensus. Where I live doctors won’t prescribe you medicinal weed if you’re under 25 usually too.

Going by casual wisdom, extraordinary claims require extraordinary evidence so I would expect the burden to be on the ones claiming that what I’m saying is bs but I guess it’s on me to bring back some reason here.
