One joint of marijuana worse than five cigarettes
July 31 : It might give you a high, but smoking just one joint of cannabis or marijuana poses as much danger to the lungs as smoking up to 5 cigarettes in one go.
The finding is based on 339 adults up to the age of 70, selected from an ongoing study of respiratory health, and categorised into four different groups.
The first group comprised of those who smoked only cannabis, equivalent to at least one joint a day for five years; the second had those who smoked tobacco only, equivalent to a pack of cigarettes a day for at least a year; those who smoked both; and the third was made up of those who did not smoke either cannabis or tobacco.
All the participants had high definition x-ray scans (computed tomography) taken of their lungs and they took special breathing tests designed to assess how well their lungs worked.
They were also questioned about their smoking habits. 75 people smoked only cannabis, and 91 smoked both. 81 people did not smoke either, and 92 smoked only tobacco.
