marijuana's going to be legal!?!?!?!

yes, indeed the dream of weed smokers is finally coming true. Assemblyman Tom Ammiano proposed this law saying that if marijuana is legalized and taxed, it would bring in about $1 billion. Could that be possible? I think so for the fact that so many people smoke illegally or get caught by the police with POUNDS of the cannabis. I only wonder once the economy is stable again will they make marijuana illegal again... How does President Obama feel about this? better yet, does he even know yet? I don't think this is a good idea, but many are going for it. (sigh) i only can imagine those who are supporting it. I'm not trying to put it down, i mean to believe r not i do believe that it's going to work... but at what price are they putting it? Are they going to set the price higher than what it was on the streets? Are they only selling little by little?
