Marijuana Legalization

I was watching a show on the History Chanel recently and it was about the legalization of marijuana.  The thing that really got me thinking was that Dutch countries that have it legalized make I think 1.2 million is what it said just from selling marijuana legally.  Every one knows how far in debt the United States is, if our country legalized it and sold it in coffee shops or gas stations, it would get our country out of debt.  Guarnteed. 

I don't understand why alcohol is legal and marijuana is not.  There is more deaths by alcohol than any other drug in the United States.  As you can see here by this chart, alcohol is third in causes of death in the United States. To tobacco, which is also legal and obesity. 

Tobacco	435,0001
Poor Diet and Physical Inactivity	365,0001
Alcohol	85,000 1
Microbial Agents	75,0001
Toxic Agents	55,0001
Motor Vehicle Crashes	26,3471
Adverse Reactions to Prescription Drugs	32,0002
Suicide	30,6223
Incidents Involving Firearms	29,0001
Homicide	20,3084
Sexual Behaviors	20,0001
All Illicit Drug Use, Direct and Indirect	17,0001, 5
Non-Steroidal Anti-Inflammatory Drugs Such As Aspirin	7,6006
Marijuana	07

As you can see above Marijuana is at 0 deaths per year caused from smoking.  Alcohol and tobacco combine for a whopping 520,000 deaths a year,  but they are both legal. I'm not saying it should be legal so I can smoke it, but that it should be legal because it would get our country out of debt.
