It’s not exactly a new question.
In the early years of legalization, for instance, people were often concerned about the health risks of pot smoking.
Yet as cannabis usage has skyrocketed, so too have concerns about its impact on the lungs and the digestive system.
And now the World Health Organization has released a draft report warning that pot smokers can get lung cancer.
What’s the science behind the claim that pot can cause lung cancer?
In short, there’s not a whole lot of scientific evidence to support it.
It’s based on a review of a variety of studies that looked at a range of studies and found no clear link between marijuana and cancer.
But there’s some solid evidence.
A number of studies have found a link between the use of marijuana and lung cancer, including studies from Canada, the United States, the Netherlands and the UK.
The biggest study, from the US, found that marijuana users had a 40 per cent higher risk of developing lung cancer compared to non-users.
There’s a link, but it’s hard to know exactly how much it might be.
There are several possible explanations for the higher lung cancer risk, according to experts.
Smoking marijuana might increase the amount of carcinogens in the air it exhales, such as carbon monoxide.
Smoking weed may also increase the chance of the lung cancer developing through the normal process of cell division.
Other possible reasons include a genetic predisposition for the development of the disease, such in people who smoke cigarettes, or because of the chemicals in the cannabis smoke.
Another possibility is that it’s simply a matter of habit.
“Smoking pot doesn’t lead to lung cancer,” says Dr Sarah Jaffe, an internist at the University of Queensland and a member of the Australian Institute for Cancer Research’s Centre for Tobacco Control Research.
She says that people who are more likely to smoke pot might have an easier time maintaining their smoking habits, while also being less likely to develop lung cancer as a result.
The bottom line, says Jaffe: It’s too soon to tell what the real risks of smoking weed are.
There have been no long-term studies into the health effects of cannabis use.
But one thing is certain: marijuana is still a very controversial topic, with some saying it’s dangerous and others calling it a gateway drug.
So if you’ve been considering smoking pot, it’s probably worth checking with your doctor before you start.
