I don't know a lot about marijuana, but this......
My friend Frank, who was 57, was a pot smoker. Not a cigarette smoker. He was diagnosed with terminal lung cancer August 2001 and passed away October 2001.
He smoked, on average, 6 - 8 joints a day. This is an unfiltered product which is being taken into your lungs just like a cigarette.
To me there is no difference between a joint or a cigarette. To my friend the end result is the same as a smoker.
I have chosen not to smoke for 3 Weeks 6 Days 23 Hours 36 Minutes 37 Seconds. Cigarettes not smoked: 1063. Money saved: C$425.35.

"Study finds cannabis and
tobacco equally bad"
August 13, 2002
New Zealand Herald
Smoking cannabis is as bad for your lungs as smoking cigarettes, says a Dunedin-based study.
"You can't say cannabis is safe any more than you can say tobacco is safe. The health message is clear - don't be burning vegetable matter and inhaling it," said Dunedin School of Medicine associate professor Robin Taylor, one of the study's authors.
Smoking both cannabis and tobacco narrowed people's airways even more than smoking only one of the substances.
The study involved examining how much breath about 900 people aged 18 to 26 could expel forcefully from their lungs.
People who smoked cannabis or tobacco expelled less air in a second than non-smokers and took longer to expel all the air from their lungs because their airways had narrowed slightly.
Airflows decreased even more when people smoked both cannabis and tobacco. Smokers' breathing and airways were affected by the tar in tobacco. Cannabis had similar levels.
The study group members were examined three times in eight years.
While all were healthy and differences in their airflows subtle, the figures highlighted a trend, Professor Taylor said.
The information was gathered as part of the Dunedin Multidisciplinary Health and Development Study and analysed by respiratory researchers.
The researchers' interest was sparked by cannabis use increasing significantly in most developed countries in the past three decades and people increasingly questioning if it was worse than smoking tobacco.
Professor Taylor said the study was complex because group members' lung development was at different stages.
Lungs grew and became more efficient during childhood and adolescence, then efficiency started naturally declining in the mid-20s.
The study would continue when the people were aged 32 to 37.

| A quick look around finds this: |
Pot has more up to 4 times more tar than tobacco, and as with tobacco, you never really know what other added chemicals you're getting. (PCP? Embalming fluid? Parsley?)
Some more selected pot info:
How does marijuana affect the heart?
Marijuana use increases the heart rate as much as 50 percent, depending on the amount of THC. It can cause chest pain in people who have a poor blood supply to the heart - and it produces these effects more rapidly than tobacco smoke does.
How does marijuana affect the lungs?
Scientists believe that marijuana can be especially harmful to the lungs because users often inhale the unfiltered smoke deeply and hold it in their lungs as long as possible. Therefore, the smoke is in contact with lung tissues for long periods of time, which irritates the lungs and damages the way they work. Marijuana smoke contains some of the same ingredients in tobacco smoke that can cause emphysema and cancer. In addition, many marijuana users also smoke cigarettes; the combined effects of smoking these two substances creates an increased health risk.
Can marijuana cause cancer?
Marijuana smoke has been found to contain more cancer-causing agents than is found in tobacco smoke. Examination of human lung tissue that had been exposed to marijuana smoke over a long period of time in a laboratory showed cellular changes called metaplasia that are considered precancerous. In laboratory test, the tars from marijuana smoke have produced tumors when applied to animal skin. These studies suggest that it is likely that marijuana may cause cancer if used for a number of years.

Somewhere along the way, I stumbled on a side-by-side listing of chemicals in cigarette tobacco and marijuana, but I can't seem to find it just now. It's very interesting reading to be sure!
Bottom line: smoking ANYTHING is just not a loving thing to do to your lungs, heart, brain, bones, muscles, reproductive system, neurological system, digestive system ...

Many people think smoking cannabis is safe
Smoking pure cannabis is more harmful to lungs than tobacco, a health charity is warning. A study by the British Lung Foundation found that just three cannabis joints a day cause the same damage as 20 cigarettes.
Dr Mark Britton, chairman of the British Lung Foundation, said: "These statistics will come as a surprise to many people, especially those who choose to smoke cannabis rather than tobacco in the belief it is safer for them.
"It is vital that people are fully aware of the dangers so they can make an educated decision and know the damage they may be causing."

Dr Britton emphasised that the British Lung Foundation report - called A Smoking Gun? - was "not about the moral rights and wrongs of cannabis".
But, he said, they simply wanted to make sure people were completely clear about the respiratory health risks involved.
Surveys carried out earlier this year showed that 79% of children believed that cannabis was 'safe'.
Only 2% understood correctly that there are health risks associated with smoking the drug.
The British Lung Foundation report also shows that the health dangers of cannabis have substantially increased since the 1960s.
That means that clinical studies carried out in the sixties and seventies may well underestimate the ill effects of smoking the drug.
This is due to increased amounts of THC - or delta-9 tetrahydrocannabinol, the major active chemical compound - in the cannabis consumed today.
In the brain, THC connects to specific sites called cannabinoid receptors on nerve cells and thereby influences the activity of those cells.
Many cannabinoid receptors are found in the parts of the brain that influence pleasure, memory, thought, concentration, sensory and time perception, and coordinated movement.
Dame Helena Shovelton, chief executive of the British Lung Foundation, said: "Puff and inhalation volume with cannabis is up to four times higher than with tobacco - in other words you inhale deeper and hold your breath with the smoke for longer before exhaling.
"This result in more poisonous carbon monoxide and tar entering into the lungs."
The British Lung Foundation is calling for the government to implement a public health education on the health risks of cannabis.
The charity will also be pushing for further research into cannabis and the lungs and its potential link with the development of chronic obstructive pulmonary disease.
