Dope far worse than fags
SMOKING a single marijuana joint has the same impact on breathing capacity as up to five cigarettes.
It follows a study published in the British journal The Lancet on Saturday that said there was now clear evidence of a link between Cannabis Smoking and Mental ill-health.
In the study now reported in Thorax, Medical Research Institute of New Zealand doctors recruited 339 volunteers, who were divided into four categories - those who smoked only cannabis, those who smoked only tobacco, those who smoked both, and those who smoked neither.
Cannabis-only smokers were defined as those who had smoked the equivalent of at least one joint a day for five years; tobacco-only smokers were those who had smoked the equivalent of a packet of cigarettes a day for at least a year.
All were scanned by computed tomography (CT) to get a high-definition image of their lungs and were given tests to assess their airflow, the term for their respiratory efficiency.
The most serious damage was found in tobacco smokers - both tobacco-only and combined users - who were the only volunteers to have emphysema, a degenerative and crippling lung disease.
Cannabis smokers had lighter symptoms, such as wheeze, cough, chest tightness and phlegm, which tobacco smokers also had.
But the CT scan also revealed that, among cannabis smokers, fine damage had occurred to their lungs. This had happened in small fine airways that are important for bringing in oxygen and taking away waste gases. As a result, their lungs had to work harder.
The extent of the damage rose in proportion to the number of joints that had been smoked.
In statistical terms, each joint that was smoked was the equivalent of smoking between two and a half and five cigarettes in one go for impairing lung efficiency.
The discovery of this hazard is "of major public health significance" given that cannabis is the most widely-used illegal drug worldwide, an estimated 160 million people use cannabis, also called marijuana.
The reason for cannabis' heavy toll on the lungs stems is that joints are usually smoked without a filter and are smoked down as far as possible, which means the smoke is hotter when it arrives in the lungs.
In addition, cannabis users tend to inhale smoke more deeply and then hold their breath to get a bigger "high".
Reminds me of that song.
"Smoke smoke smoke that cigarette"
"Smoke smoke smoke"
"AND YOU WILL SMOKE YOURSELF TO DEATH".
"Tell St Peter at the golden gate"
"That you hate to make him wait"
"But you just gotta have another Cigarette". Cough cough.
The tax paid by one smoker of 20 cigs over 50 years, about $200,000, worth more than $1,000000 if saved. Most of this tax goes to Cancer research, we are told?
The Govt saves $150,000 or about on paying state pensions for an average 7.5 years for looney smokers who die earlier.
Yet its strange how a little old bloke I knew until recently(Woody)smoked about 40 rollies a day until he cashed in at 97 years old, sort of a lottery ennit.
