You don't need a lawyer for corporate documents. Legalzoom works fine... California C Corp (if your exit is acquisition and Delaware Corp (if your exit is public). Most VC's have their own army of lawyers and if you need a lawyer when you have a offer in hand, then any will do.

Those two lawyers will be very different. A lawyer familiar with the drug laws will understand a jurisdictions ordinances and the states criminal code. Probably better to get a consultant... give him some equity for subject matter expert.
