Lol wherever high-school kids and budget minded people buy weed. That is where you buy in gr increments. Also any store I have ever been in has sold grams.

Ohhhhhh, British Columbian and ex professional here on this one.

Personal "bulk" sales are usually some in 1/8ths (3.5 grams) or more but in stores, the first page of their lil booklet is usually half or full gram pre rolled joints.

Admittedly, for what it's worth, first time I saw this meme in the wild was at a pot shop while buying a pre rolled gram.

You are either young or have middle class dealers. In 2007, you definitely did buy weed by the gram, and hydroponic stuff could be $20-$30 per gram in some areas if supply was scarce. Of course, places with competition had better prices, but some rural areas really price gouged.

Ghetto dealers often sold bags by the price alone. $10 was usually 2 grams to an 8th of either backyard weed or Mexican weed that often had little bits of twine and the occasional Hispanic hair in it from when it was put in a bale and taken across the border. Some dealers would also sell nickel bags ($5) that was .75 to 1 gram—basically just enough for one blunt.

I have been glad that I’ve gotten to see the weed industry evolve heavily over my lifetime, and I know that I only see about 20 years of it. I’m sure the old heads from the 70’s would have real stories to tell. In the words of Bill Burr, “you used to buy your weed by the pillowcase.”

Perhaps the people that don't live in the US?
