How do I find drugs in 4.2?

I've read and seen alot of video's about people telling me to go to Pyro and do certain missions to get drugs. But when I go to check the missions out myself I see that all the missions they were talking about are not in the game anymore.

Does anyone know a way to get Drugs in star citizen without buying it somewhere? I've heard that you can get a massive profit from selling drugs.

Thanks in advance!
