Hypothetical prices for Chicago, IL.
Meth - rarely available, maybe $150/g
Coke - always available, quality varies, but usually good $50/g, $130-150/ball
Weed - seems like schwag-quality is rarer than average, but I wouldn't look for that stuff; $60/8th nugs, quality ranges from mid-grade to low-ish dank, there really is no true "dank" at that price, ounces of this available in some markets @ 150/oz, but can fetch 400/oz in other markets
MDMA - seems rare, but I wouldn't look for it - $25-30/pill quotes lately
acid - rumors...
shrooms - availability sporadic, but when it's around, its very available 30/8th
H - only know of street market availability, price unknown
PCP - availability on non-street market very rare, price no idea...
crack - street market only (from my POV), $10 rocks decent quality, though they'll say $20 if you look like a clueless white kid
OC's - availability changes, $.50-$1/mg, depending on source, consistent source is rare
Dexedrine - availability constant, $2-4 / 10-15mg time-release or 10mg tablets
ketamine - $80/vial, but people seem pretty tight-fisted on this shit
40's of 211 Steel Reserve - $3 unlimited availability
