"Experts are warning that the public dangerously underestimates the health risks linked to smoking cannabis."
"The British Lung Foundation carried out a survey of 1,000 adults and found a third wrongly believed cannabis did not harm health.
And 88% incorrectly thought tobacco cigarettes were more harmful than cannabis ones - when the risk of lung cancer is actually 20 times higher.
The BLF said the lack of awareness was 'alarming'.
Latest figures show that 30% of 16-59 year-olds in England and Wales have used cannabis in their lifetimes.
A new report from the BLF says there are established scientific links between smoking cannabis and tuberculosis, acute bronchitis and lung cancer."
