Potheads stink.
Here in Oregon, you smell the shit everywhere. You smell it walking down the street in a neighborhood, you smell it on people's clothing.
Having nothing whatsoever to do with decriminalizing it.
Actually, it has everything to do with it. When you tell people its respectable and ok to get loaded on grass, a number of people will do it all the time and it will appear.
Sure, people still get stoned if it isn't legal/respectable, but they are more discrete about it.
Very similar to the She-Male situation. There were always fellows who like to wear ladies' clothes. But they did it at night, in the red light zones, and when they went to work in the morning they wore a suit and tie. The modern era's normalization has led this to be seen in respectable company.
