I'm all for it!
I only see one problem though... Too many people allow the U.S. Government to tramp all over themselves!! For instance, in the 1980's the Fed's said "Either bring the drinking age up to 21 or we're cutting your Federal highway money." Well, people backed down and now the age is to 21 years of age.
But yes, if one state were to make marijuana legal. Oh wait, Alaska is almost there! Aside from that... States would see the money making scheme and jump on board!
Unfortunately people get old and have responsibilities. Kids, car payments, mortgages, food bills, gas prices..etc. Once this happens some tend to become more conservative and less outspoken on issues that truly concern them but cannot speak out in fear of local or national retaliation. Or some people just don't care what happens... Which is quite sad, it may not impact or affect you now but just wait and see... Some day it might!
