Effects of Smoking Weed

While 7 was still smoking, I'd never heard of arteriosclerosis or emphysema. I knew the permanent wheezing and coughing and the ever-increasing asthma and bronchitis attacks were a direct result of my smoking. But though they caused me discomfort there was no real pain and I could handle the discomfort.
I confess that the thought of contracting lung cancer terrified me, which is probably why I just blocked it from my mind. It's amazing how the fear of the horrendous health risks attached to smoking are overshadowed by the fear of stopping. It's not so much that the latter is a greater fear, but that if we quit today the fear is immediate, whereas the fear of contracting lung cancer is a fear of the future. Why look on the black side? Perhaps it won't happen. I'm bound to have quit by then anyway.
We tend to think of smoking as a tug-of-war. On one side fear: it's unhealthy, expensive, filthy and enslaving. On the other side the pluses: it's my pleasure, my friend, my crutch. It never seems to occur to us that this side is also fear. It's not so much that we enjoy them, but that we tend to be miserable without them.
Think of heroin addicts deprived of their heroin: the abject misery they go through. Now picture their utter joy when they are allowed to plunge a needle into their veins and end that terrible craving. Try to imagine how anyone could actually believe they get pleasure from sticking a hypodermic syringe into a vein.
Non-heroin addicts don't suffer that panic feeling. Heroin doesn't relieve the feeling, on the contrary, it causes it. Non-smokers don't feel miserable if they are not allowed to smoke after a meal.
It's only smokers that suffer that feeling. Nicotine doesn't relieve it, on the contrary it causes it.

The fear of contracting lung cancer didn't make me quit because I believed it was rather like walking through a minefield. If you got away with it - fine. If you were unlucky you stepped on a mine.
You knew the risks you were taking and if you were prepared to take the risk, what had it to do with anyone else?

So if a non-smoker ever tried to make me aware of those risks, I would use the typical evasive tactics that all addicts invariably adopt.
'You have to die of something'.
Of course you do, but is that a logical reason for deliberately shortening your life?
Quality of life is more important than longevity'.
Exactly, but you are surely not suggesting that, the quality of life of an alcoholic or a heroin addict is greater than that of someone that isn't addicted to alcohol or heroin? Do you really believe that the quality of a smoker's life is better than a non-smoker's?
Surely the smoker loses on both counts his life is both shorter and more miserable.
‘My lungs probably suffer more damage from car exhausts than from smoking;
Even if that were true, is that a logical reason for punishing your lungs further? Can you possibly conceive of anyone being stupid enough to actually put their mouth over an exhaust pipe and deliberately inhale those fumes into their lungs?
THAT'S WHAT SMOKERS EFFECTIVELY DO!
