I am not in any legal state, but this is an interesting read. For those who stated a bill was passed making it illegal for the feds to interfere with legalized states...since when does the federal govt follow its own rules? There are federal laws about illegal immigration, but they don't seem to be following that one.
I have zero idea on what bulk prices are, but in Iowa, the street price for ANYTHING starts at a min of $20 per gram plus. Your lucky if the seller even knows what strain they have, and if they say a name, good chance they are bullshitting. Usually it is bricked shit. Finding actual bud can be a challenge.
I don't make BHO, but I understand from any liquid that boils off above freezing, it either takes time for it to evaporate off naturally, or a period of time in a vacuum chamber to speed it up. The problem I see is one doesn't exactly know if who made it actually did a good purge or allowed enough time for it to evaporate.
Dabs? never seen it sold here. Some make it, but I have never seen or heard of it being sold.
Costs and profits...well, the more states that allow personal growing (that is a good thing), the more people don't need to buy elsewhere.
