My love of kfc chicken skin and beer probably (one day) will have a flow on effect to society. Everything everyone does Does so. Many cases the effect is too small to be tangible. If theres no direct effect (ie smoking a joint then jacking a car and smashing it into the QVB) then its not worth worrying about and is small enough to say theres no measurable reaction, at least none more so than any other recreation.
wont get into the topic. Live and let live
