I think that part of the suspicion of research like this comes from years of complete lies about the dangers of cannabis. The fact that is still classified as a schedule-1 drug even though we know that it's nowhere near as dangerous as it was claimed.

It's also important to note what affect cannabis has on the pharma-industries. It's a "weed" that can help cure a huge variety of serious issues with far less cost, side-effects and risks than prescription drugs. Given the influence of the big-pharm on medical publications and research, I assume some people will be suspicious of any research which says anything bad about something that might affect their bottom line.

I'm not saying these arguments are valid for this article, just explaining another angle why some people might be suspicious.
