The pipe that smokers use is plastic, and non-porous, so none of the carbon-monoxide is allowed to escape. A recent study in the South African medical journal measured levels of carbon monoxide in the blood. Five minutes after smoking, carbon-monoxide increased by 40% in cigarette smokers and by 482% in hubbly smokers, and so the volume of carbon monoxide is huge, and of course carbon monoxide is the same thing that you use when you want to commit suicide. You attach a hosepipe to your car's exhaust system, and you sit in the car and it's the carbon monoxide that kills you.
We conducted our own tests at Envirocon Instrumentation using a portable gas analyser from Japan. We asked a seasoned cigarette smoker to blow a mouth full of cigarette smoke into a bag. This was then extracted by the machine and showed a sulphur dioxide or SO2 reading of 6.6 parts per million, and a carbon monoxide or CO reading of 300. We then asked a young hubbly smoker to do the same thing. A bag full of hubbly smoke was attached to the machine and the results were dramatic. The digits continued climbing until the CO levels were out of range, over the limit of 500, and the sulphur dioxide level was 10 parts per million.
I don't smoke hubbly, but I always thought it would be cool to get one. Now I don't think so. Currently I roll my own cigarettes with Drum tobacco. Is there a tobacco on the market for hubbly bubblies that are not chemical laden, like you get for hand-rolled cigarettes, or is hubbly smoking just a no-no? I asked the guy at the tobacco shop a few days ago if you can use Golden Virginia or Drum tobacco in a hubbly (since I don't have a clue), and he said no, those are for hand-rolled cigarettes
only. So I asked him if there is a natural organic tobacco available for hubblies, and he said not to his knowledge. He didn't seem like the brightest pencil in the packet anyway, and said the 'only' tobacco available everywhere for hubblies are the flavoured ones (cherry, vanilla, banana etc. etc.) I also think the plastic tube for inhaling can't be that good + no filter.
A hubbly bubbly just always looks so social to me...but I might just admire the activity from a distance until I know for sure.
