It's all BS. I don't see any of those articles negatively affecting MJ in the long run. Americans do a lot worse to their bodies on a daily basis. The consumption of beer for example or double quarter pounder cheeseburgers aren't exactly healthy for anyone and yet hundreds of millions of dollars worth of those goods are sold each year. So MJ will be fine. Look at this as a buying opportunity and benefit from the stupidity of others. Their weakness will be your strength.
The Scum will sell their soul's for a vote. They would legalize Crack to be re-elected. Legalization is coming, voting season is right around the corner.
