Warning over cannabis lung harm

‘Heavy cannabis users may be at greater risk of chronic lung disease – including cancer – compared to tobacco smokers, two studies suggest.

One study found a higher risk of lung cancer for those who smoked one joint a day compared with those who smoked 20 cigarettes a day over the same period.

Another found bullous disease – a form of emphysema – occurs 20 years earlier in cannabis smokers.

The studies appear in Respirology and the European Respiratory Journal.’
