The letter could read something as follows,
(just some ideas)

To whom it may concern,
I am a medical patient, and can not afford the medicine the Licensed producers are selling, because the prices are outrageous. The cost of cannabis is inflated due to its prohibition, it is a inflated black market price,so when the DOH says the producers can charge a fair market value, that is an inflated market value. It costs no more than 500.00$ to produce one pound of dried cannabis if grow in controlled growing environment indoors. The producers are charging on average of 4,000.00$ to 6,000.00$'s per pound. Where is all the other money going?
If for some reason the DOH wants to keep the price high, please reconsider, most people who have medical marijuana, cannot afford these inflated prices, there is no reason to make the patients suffer, just to possibly prevent one patient from selling it to make money, as it is a person can buy cannabis for less than half on the street here in new mexico, and in Colorado, California, etc. it goes as low as 1,200.00$ a pound with the growers still making their money. That equates to 2.00$-3.00$ a gram as opposed to 12.00$-14.00$, for the sick patients of new mexico.

what do you guys think?
I took some points from some other people on the boards.
