Should marijuana be legalized and taxed in the US, like alcohol?

Either on a state level or a federal level: The production costs in the US would be a small fraction of the street prices paid today. If it could be taxed to the point of not exceding present retail prices, thus maintaining what the present market will bear, this could pour billions into the treasury over a short period at a time when many states and the US is crippled in debt. Sounds good to me.
