What are the costs of offensive drugs and poisons in *Cyberpunk 2020*? That is, the various types of drugs and poison set out in the Friday Night Firefight section that can be delivered via airgun, dartgun, or squirtgun.

I can find effects but not rules. It is referenced under the Ammunition section in the Gear chapter, but different types are not priced differently (which clearly is not the intention.) If possible, I would prefer rules set out in the Core Rulebook.
