Asthma
Drops
 
 
Child
asthma
has
dropped
 
in
England.
 
This
 
is
since
 
the
smoking
ban
 
in
2007.
Smoking
 
in
public
places
 
was
banned
then.
 
The
ban
 
was
 
to
protect
people
 
who
do not
smoke.
 
Asthma
 
can
cause
breathing
problems,
wheezing,
coughing
 
and
 
a
tight chest.
More than
5
million
people
 
are
treated
 
for
asthma
 
in
 
the
UK.
