Drug and BTL street prices, How much should I charge from Krytachroniconalite... I mean deep weed? Options

[Beetle]

I've dug through the BBB a few times looking for prices and availability on combat drugs and BTL's and haven't found anything aside from their basic game mechanics. Is there an errata suggesting prices some where or am I blind and just missed the table somewhere?

I know it all should vary on quality/purity for drugs and content/type of BTL, contacts, but are there any guidelines for this that you use?
According to the background my player wrote I've got two players that used to have nova coke addictions, another regularly smokes deep weed, and two used to have BTL addictions. I'd like to incorporate these things into the game for temptation purposes for my group. Somehow I imagine deepweed goes for a bit more than the average price of high grade pot. "This shit right here..."

How much would you charge for dime bag of deep weed? How much for an eightball (3.5 grams) of novacoke? etc.
