I see the drugs are bad crowd are out in force. I'm sure they'll treat any negative stories about drug users or the effects of drugs with just as much scepticism, prejudice, and criticism as they demonstrate here. How wonderful it must be to be powered by objective reason and free from confirmation bias.
If you read the article, I believe it is more of a "we are studying it and there is a lot to do" than "drugs are good".
I think a very important part is:
> For example, I’m interested in the effects of THC versus CBD. We don't have any of that information in the UK Biobank. Most people in this study were using cannabis quite a while ago, and cannabis at that time looked very different from what’s available today. That context really matters. It’s a complex picture.
i see your point but think about it this way. A bowl or a joint holds a certain amount. People fill mostly the same amount and dont regulate it by thc content
Of course junkies would jump on this paper, while conveniently ignoring meta-analyses.
"Longitudinal and twin studies report larger declines in IQ among cannabis users than their non-using peers but it is unclear whether these findings can be attributed to cannabis use or to genetic, mental health and environmental factors."
Yes, and I'm sure virtuous non-"junkies" such as yourself hold all articles that report or demonstrate negative findings about recreational drug use to the same exacting standards. It must be freeing to have a completely objective perspective and be free from the clouds of any ideology or bias.
