>could go for $3k-$4k to a dispensary. Now the high end seems to have fallen out and you're maybe lucky to get half of that.
For comparison, bulk price of tobacco is a few bucks a pound. Admittedly I am not an expert in marijuana vs tobacco cultivation, but I doubt it's 1,000 times more expensive. Ultimately, the problem with profiting in a legal marijuana industry is that people simply don't smoke that much pot.
Say that there's 260 million adults in the US and they all smoke 1 joint per day. Assuming:
1 joint = 1 g of marijuana
1 lb = 454g
1 acre can yield 600 lbs of marijuana
1 farm is 1000 acres
If you do the math, that means we need roughly 350 farms worth of marijuana. Or in terms of acreage, roughly 0.04% of all the acreage in the U.S. under cultivation. In other words, even if we assume a ridiculous level of smoking there's simply not a huge demand for pot. Using more realistic amounts, a handful of large farms could produce all the marijuana consumed in the country.
