Question

recently,some scientists invented electric-cigarettes。such cigarettes do not need to be lighted with matches and they do not give out smoke。what do you think of this invention？

Answer 1

I don't think so.
Though the cigarettes do not need to be lighted with matches ,they also do bad to people'health.
That's my personal opinion.

Answer 2
