Using the above picture, they explained that just because one thing is ‘associated’ with another doesn’t mean that one was actually caused by the other.
In fact, Professor of Public Health Sciences and

Giving an example, drug reform doctor Alex Wodak suggested that, even though smoking cigarettes is three times more common in kids who have vaped, vaping isn’t necessarily a gateway to smoking.
He pointed out that if the same logic was applied to this image, then it would be fair to assume that the seagull must have landed on the metal bar and bent it.
