Answer

Only when we human beings find some substitutes for tobacco,can we truly get rid of it (can it be completely removed from our lives). It's never enough to try to terminate the circulation of tobacco by putting on forceless no smoking slogans or offering plain advices.

Answer

I am no translator but I would express it something like this:

"Therefore only after mankind finds a replacement/substitute for tobacco can we truly eliminate it from our lives; merely relying on smoking cessation advice and anti-smoking publicity is far from adequate."
