OK, let's assume - for argument's sake - that smoking marijuana can
cause heart attacks.
1) Smoking marijuana can cause heart attacks.
2) It is better to die quickly of a heart attack than to die slowly of
cancer.
3) The more chance you have of dying of a heart attack, the less
chance you have of dying of cancer.
4) Therefore, smoking marijuana is good!!
But, to be fair, I should point out that it can also have the
following side-effects:
(a) Poor short-term memory
(b) Poor concentration
(c) Reduced motor co-ordination, e.g. when driving a car
(d) Apathy
(e) Lethargy
(f) Poor short-term memory
