Switzerland (which is supposedly way ahead of the US for legalization) had a vote in November and a lot of growers voted AGAINST legalizing it! it might sound hypocritical, but the underlying fact is that when it's illegal there are practically no regulations. You can grow whatever you want however you want because it's unregulated.
Once it becomes legal then who knows how much government intervention will there be?
Notice how even in this NH program they repeat that "cannabis nowadays is way stronger than it was back then" with a certain negative connotation... hint hint.
The president is just there to give you the impression that you have freedom, choice, etc. You don't.
we'll wait and see...
