Fairly self-explanatory, add the codeine based drink lean (red, purple, both, or even more color variants) with a possibly more Withmore appropriate name.
Effects would be similar to weed stat-wise, but weaker (no shitting yourself after two hits), with overdosing something along the lines of lower heart rate, decreased breathing rate, cramps, then passing out?
Withdrawals would be stuff like cramps, increased heart/breathing rate, anxiety, etc.
