Our "High" Achievement

The President of the United States, Barack Hussein Obama, has recently declared that he does not think marijuana is any worse than alcohol or cigarettes. Obama should be the definitive authority on these matters because he has indulged in all three. I have a relatively libertarian view but would like to know how many people perform better under the influence of narcotics or alcohol than they would substance-free? If someone has terminal cancer, or is constantly nauseous because of chemotherapy or radiation, or is fighting glaucoma, let them puff away on their joint, but the recreational use of drugs only destroys lives. Too much permissiveness is crippling our culture.
