Synthesizing some simpler drugs sounds feasible even with amateur equipment, but still far from trivial. But I can't see that working reliably without the ability to do proper analytics on all steps. And regular people don't just have an NMR spectrometer at home. Chemical reactions usually don't have a single product, other side reactions are possible. And they also don't use up 100% of the educt, so you have to get rid of that as well. Purifying your products and making sure they're actually what you want is essential. Getting the dose right is also hard if you don't know how pure your product is, and if you don't have analytical scales (or work at a very large scale that a kitchen scale is enough).
