Man oh man I love how people try to justify Marijuanna.
Now don't get me wrong I think if Alchohol is legal then Marijuanna should be as well, since alchohol is far more dangerous. However the Canadian Government did research and found that Marijuanna does indeed damage the brain. You can try to refute the study all you want but having known pot smokers for years I see a massive decline in intelligence.
As for Gateway drug, you can't refute that either. Even if it was perfectly legal it would still lead people to try other drugs. I know two people personally who started smoking weed and moved onto Cigerettes (Another thing I think should not be legal). I also know someone who moved onto Meth , Ex etc...etc... Now sure the drug dealer may have sold them on meth, but what about the cigerettes? No dealer tried to get them smoking cigerettes, but they thought if Marijuanna was okay maybe smoking other things was okay too.
As for the driving factor. I drove a couple times with a friend who was high. Its true he thought he was driving better. But he was paranoid as heck. He'd stop early when he thought the light was going to change. He always hesitated to change lanes and was constantly looking back and around. Then a cop drove by and he started freaking out. Driving with him was just as scary as the time I was dumb enough to take a ride from a drunk guy. Marijuanna impares your judgement, it makes many paranoid. Paranoia can lead to accidents and other things, I've seen planty of police chases on TV where the drivers were high and even though they only ran a stop sign or were speeding they decided to run.
Now I agree yet again that alchohol is worse, but just because something bad for you is legal doesn't mean it all should be. You mention caffiene, to overdose on caffiene you would need to drink like 15-cans in one sitting (Adults) now how many cans do you think the average person drinks? Can you even drink that many cans fast enough to over dose?
Now you could argue Salvia is another gateway drug but is legal. Well in Canada for example that is no longer the case.
I can honestly say I have never tried an illegal drug or controlled substance. I also stopped drinking alchohol over a year ago. I think Alchohol should be illegal alongside marijuanna. However you are correct their is alot of money to be made in legalizing alchohol, but should we be legalizing everything just for money.
The reason alchohol became legal again was because the majority of american's were drinking it, the reason cigerettes are legal is because everyone got hooked on them and too many people were smokers before the Governments knew what they were doing. The reason pot will become legal is because a healthy minority of the population wants it so.
We live in democracies and in democracies the population makes the laws. But just because something makes you feel good, kills pain or gives you a high does not mean it should be legal. Also the majority of voters still do not want pot legal. If so many wanted it legal then their would be more protests, larger protests and more voters would vote in elections for people that want pot legal.
Just look at the Marijuanna party here in Canada, or the NDP who also want pot legal. Now look at their votes? Do they have many supporters? Not enough to even make second place in an election. Infact the Marijuanna Party has to my knowledge never even one a single seat locally, provincially or nationally.
The American people don't want pot legal, the government doesn't want pot legal. A few hippies and hill billies should not be allowed to run the country. Eventually I'm sure it will become legal much like alchohol did, but it just goes to show you how our society doesn't give a crap anymore. The minorities don't care what their addiction or usage of alchohol, marijuanna or cigerettes do to the people around them. They don't care about the inflated health bills the people they kill drunk driving the families they tear apart.
All this minority cares about is their own feelings, it makes me feel good there for I should do it.
