Try this:

str = 'and stuff and nice things not bad girls not greasy boys
and girlsandboys'

smoking_table = {'and'=>[], 'not'=>[]}

pieces = str.split(/(and |not )/)
len = pieces.length

index = 0
while index < len

  case pieces[index]
  when 'and '
    smoking_table['and'] << pieces[index+1].strip
    index +=2
  when 'not '
    smoking_table['not'] << pieces[index+1].strip
    index += 2
  else
    index += 1
  end

end

p smoking_table
