god bless canada for sure! BC bud!
Anyways,
An eighth of some Dank nug(high quality) is about 3.5 to 4 grams and can cost anywhere from 40 bucks to 60 bucks.
and usually you only buy 8ths of weed when they're Dank, Chronic, High Quality etc...
Now a quarter of mid grade which is about 7-9 grams will cost you anywhere from 35 dollars to 50 dollars
A quarter of shwag which also is about 7-9 will cost from 20-30 dollars.
a quarter of some Dank nug although you might be surprised, will tend to be 6-8 grams and it can run you anywhere from 65 to 175 dollars.
See the thing with weed is there are sooo many variances of the herb and with it the prices vary as well. You get different highs as well and also that factors in to the wide variety of prices for it.
The price of marijuana is not linear. But pretty damn close to it.
And another major factor when it comes to weed is location. In places where high quality marijuana is very common such as Humboldt County in California or Boulder, Colorado the price of a quarter ounce will be greatly reduced simply because the there's more supply and the demand can be met. The value of is not as high as it would be in oh say Neosho, Missouri. Anyways, even though dealing and having a grasp of the way marijuana and other drugs are sold, you also get a little hands on with marketing & economics without the need of a degree or other prerequisite...well, there are prerequisites but that's a totally different subject.
