I noticed you didn't say just "cannabis" previously but specifically "cannabis smoking" causes cancer but now you try and backtrack and pretend you are just saying the is no evidence that "cannabis" itself doesn't cause cancer and hope I wouldn't notice your attempt to be evasive to avoid admitting you are wrong.
lets go back to the issue of cannabis smoking causing cancer;

Cannabis smoke contains many of the same cancer causing substances (carcinogens) as tobacco - at least 50 of them. In addition, cannabis is often mixed with tobacco when smoked.
One of these carcinogens is benzyprene. Benzyprene is in the tar of both tobacco and cannabis cigarettes. We know that benzyprene causes cancer. It alters a gene called p53, which is a tumour suppressor gene. We know that 3 out of 4 lung cancers (75% ) occur in people who have faulty p53 genes. The p53 gene is also linked to many other cancers. ..."
why, according to you, is this website not "reputable"?
...-answer; it is because it says something you don't like. Why else?
Virtually all good science websites that say things you don't like are apparently reputable to everyone but you.
In fact, if a science websites that say things you don't like thus you shout and complain is wrong, we take that, as we should do, as evidence that it is a good science website.
This is what you don't get.
