legalise pot and make some money for USA

The sooner  they  legalise  pot the  better ,the govt can  get some revenue form this  massive business,i mean bloody hell, apart from me ,nearly every bugger in America smokes weed.....,i am sure most people need it to get  through the day 
I mean why not make it legal it will save about 17,000 lives  a year and  maybe  help out with our debt....
But of course helping people  with legalising  weed  you know  cancer and sick people  may  be too much for the govt and medical  companies  cut into their  profits .......    and of  course the govt  would not like people ,  who are  dying of  cancer  ,to get high and help  them out in their  last  days  ,  easing the pain   govt would not like  that at all you have  to  suffer....
Why  would  USA  legalise  weed  could not  keep up with Mexico and you know if the govt  get a hold of  it......... they will fuck it up  good  and  proper..................
