Do you know why leaf blowers are banned in some states?

I found out that in some states, leaf blowers are banned to use, and in my state it is not, what about you all, and how you are solving it? DO electric blowers are really worth buying?

I think some states are going that way where gas leaf blowers are banned which is weird for landscapers.  I think the battery leaf blowers are great but not sure if they are up to par for the landscaper as of now.

I read about this topic why the leaf blowers are banned, and found out that the reason for the ban is the air pollution and noise pollution that they create while blowing the leaves.
