A chemist gots to have brains to mix 'em things together so they don't go puff-piff in his face!
I want to make drugs! How do I grind chemistry?
Grinding chemistry takes a lot of raw materials - zombie brains, venom sacs, empty syringes, raw meat, pills of any sort and crank are all useful here. Making various hypos is a great way to raise your chemistry skill. Mixing pills into meals you cook on the stove is another way, although this takes a bit more time. Put one pill in the stove at a time to conserve your stocks of phamaceuticals.
Bear in mind that learning chemistry can be a very painful experience as chemistry sets and stoves have a tendency to burn you if you have low skill.
