Dear President Obama,
You invited guests to the white house to enjoy consumption of alcohol. You smoke cigarettes. You brewed alcohol in the white house. Based on the logic that was provided for your ongoing support of cannabis prohibition, your behavior and your policies are hypocritical.
Alcohol and tobacco are both highly addictive and proven killers. You appear to enjoy the freedom you have to produce and consume those harmful substances purely for your own pleasure. Cannabis users have petitioned for similar rights, so far, without success.
We the people are disappointed that our leaders apparently value social engineering over the concept of individual freedoms and liberties. We expect that you at least back up your logic with consistent policy.
