Meth labs, coke labs and weed farms are the backbone of most illegal RP. Here is how to pick interiors that support an actual loop instead of just looking gritty.

Illegal roleplay lives or dies on geography. A drug loop where everything happens in one room gets boring in a week. A loop that moves players across the map, into places they have to remember and defend, keeps running for months.
Drug lab MLOs are how you build that geography. This is what to look for.
Most MLOs are destinations. A restaurant is somewhere you go, sit, and leave. A drug lab is a stage — it is where a repeated, risky, multi-step activity happens, often while somebody else is trying to find you.
That changes what you need from the building:
An interior that fails on those looks great in a screenshot and plays badly.

Stage one: gathering. A farm, a field, a supplier. Usually outdoors or semi-outdoors, usually remote. Low risk, low reward, high time cost. Weed farms and cannabis plots do this well because they are visibly agricultural — players understand instantly what the place is for.
Stage two: processing. The lab. This is your highest-value interior and where players spend the most time standing still, which means it is also where they are most vulnerable. Meth and coke labs fit here.
Stage three: distribution. Selling. Street corners, a storage unit, a front business. This wants to be near population, because the risk is being seen rather than being ambushed.
The reason this works is that each stage has a different risk profile and a different location. Players move. Police have three separate things to investigate. The loop has rhythm.
If your entire drug economy happens in one basement, you have a task, not a loop.
Prop clearance. Processing scripts spawn props — tables, crates, equipment. If the interior is already full of static clutter, spawned props end up inside walls. Look for open floor in the working area.
Multiple ways in. One door means every raid is identical. Two or three means police have to make a choice and criminals have an escape option. This single factor changes the roleplay more than the textures do.
Lighting that reads as functional. Labs should look lit for work, not lit for atmosphere. If you cannot see what you are doing, players will complain, and the screenshots will be dark mush.
Collision on the equipment. Static props that you can walk through break immersion instantly in a room players stand in for minutes at a time.
A documented location. You need to know where it is before you buy, so you can check it does not overlap something else you own and that the travel time makes sense for your map.
Tunnel, bunker and underground MLOs are worth calling out separately because they solve a specific problem.
Above-ground labs are findable. Somebody will eventually just fly over and look. Underground and hidden interiors give you locations that require knowledge rather than observation — a player has to be told where the entrance is.
That creates something genuinely valuable: information as a resource. Knowing where the lab is becomes worth something. Players trade it, sell it, betray each other over it. You cannot script that; you can only build the conditions for it.
If you run gang roleplay, at least one hidden location is worth the money for that reason alone.
Same answer as every MLO question, and worth repeating because it gets asked constantly.
An MLO is map data. It does not touch your framework. Drug lab interiors work identically on QBCore, ESX Legacy, Qbox and standalone.
The processing script is framework-specific. The building is not. You buy them separately and configure the script to point at the building's coordinates.
This is script configuration rather than MLO choice, but it is the thing that actually determines whether the loop survives.
The failure mode is making processing too profitable relative to legal jobs. If a twenty-minute meth run pays more than a full shift as a mechanic, everybody becomes a criminal and your legal economy dies.
Keep illegal income high-variance rather than high-average. Big payouts, real chance of losing everything to police or another gang. That way crime feels worth it without being obviously optimal.
If you are building illegal RP from nothing, the minimum viable set is three interiors: one gathering location, one processing lab, one storage or distribution point. Buy those before you buy a fourth lab.
You can browse the full drug lab and illegal MLO collection to compare, and the gang and biker interiors if you want bases to run the operation out of.
One last piece of advice: walk each interior yourself, at night, with your server's actual weather and time settings. Listing screenshots are taken at noon in clear weather. Your players will be there at 2am in the rain.
