This is another post that I once made on aofroobs that is now harder to find with that forum being lost. Since people still ask me about grafts, I thought I’d repost it here. 
Since the 18.7 patch, Boosted-Grafts and Symbio-Grafts are no longer rollable as mission reward. In this thread I’ll describe where to find them now and which are available.
Grafts
Grafts are items which you can right-click to cast a specific nano. Using a Hacker Tool, grafts can be hacked to remove the profession requirement. This allows for example a doctor to cast Enhanced Senses, or an enforcer to cast Detain Suspect. In the case of combat nano’s, they can never be resisted by the target and will always land succesfully.
The lockout varies from 1h for a Ql1 Symbio-Graft to 43m 20s for a Ql200, and from 30m for a Ql1 Boosted-Graft to 13m 20s for a Ql200 Boosted-Graft.
Pro-tip: you can equip grafts as (invisible) bracers on your social tab and put them on the hotbar, so you save two inventory spots 
How to get them
Grafts are no longer rollable as mission reward, and can not be looted anymore. Any grafts that you already had still exist.
A vendor, the Den Smuggler Broker, is now available in Smugglers Den, who sells Ql200 Boosted-Grafts (not Symbio-Grafts). He is located behind the desk in the long room to the left of the room with Ash Andersen. To reach him you will need to get past a lot of level 100-120 Mantises as well as level 150-170 Smugglers. If you don’t want to fight them, calms or high concealment is the safest way to get there 
If you’re tough enough, you can also simply blitz to him and ignore all the mobs. You can access his inventory while in a fight.
The price of the grafts depends on your Computer Literacy skill. With 1000 CompLit, they cost 1.625.625.
His inventory is random and he usually has 6 to 10 grafts. He is up for 20 minutes at a time, and then despawns for 20 minutes. When he returns he has a new inventory. He cannot be killed and you cannot prevent him from despawning by holding the shop open.
