First you should calculate how much money you spend on cigarettes
for example
I was buying 1 pack of cigarettes a day  for 7.50 
very easy to calculate that  i was spending 52.5 a week or 210 a month
still does not look like a large amount of money

what if we count how much i was spending a year
that about 2520 That impressive amount of money !!!

NOW THINK WHAT YOU COULD BUY  FOR THIS
