Pretty much anywhere in the US the prices are
20$ a gram
50-60$ an eight
90-100$ a quad (maybe 120 if its very good)
140-170$ a half oz depending on quality again
280-325$ an oz
These are straight up prices. The lower number would be regs and the upper number would be a dank strain. Sure, if it is your homie they would probably be on different pricing schedule. Like if they hit you up every day or 2 and get a gram, you may drop it down to 10$ for him, or if you homie from grade school wants an oz, you might do it at the same breakdown it cost you in a pound, like 260 or 260. Its all about who you know but those prices are straight up cousty prices.
Anywhere in the US you could sell someone a 20$ gram of pot, well, maybe with the section of Northeren Cali where the shit is fucking EVERYWHERE!!
