Opium
Opium: Safest opiate per mL, used for pain and as a crafting ingredient. In-game item, not medical advice.
Use, trade-offs and mechanics
Opium is the low-potency end of the game's opiate liquids. Compare reception per volume and route: ten milliliters injected supplies four reception, while one hundred milliliters drunk supplies twenty. Equal volumes do not have equal effects across those interactions. A standard fluid container and an injectable container therefore offer different uses for the same liquid.
The community recipe produces fifty milliliters from two numberries, at least ten milliliters of bio-chem fluid and liquid supplying fifty Water quality. It requires INT 7. Opium is both a craftable pain-management resource and an intermediate material. The wiki lists morphine as a direct ingredient use and opioid-quality recipes including bruise kits, relief cream, naltrexone and L.R.D. Serum. Using every available portion immediately can remove a later crafting option.
The reference describes it as the weakest and safest opiate relative to the other game fluids. That is a comparison, not a guarantee: reception, tolerance and withdrawal still matter. Read the opioid moodles and distinguish numbing pain from repairing the injury behind it. Naloxone acts on opiate level and does not directly clear tolerance.
The listed sources include opium syringes and mini-barrels as well as crafting. An unidentified liquid is not established as opium merely because it appears in one of those containers. Keep the named fluid, the intended route and the crafting requirement separate when organizing supplies.
