Drugs for Vampires.

Vampires and drugs are an interesting combo. In most books vampires can not ingest drugs directly but need to have a human take them first then drink from the human. Even under those circumstances it is unlikely the vampire will get high for long. The rare case however is when a drug has been invented just for the vampire. It's a difficult situation for most involved. At least you get a crazy vampire running around killing for his next high. At best you have a cure for some vampire disease. Most of the time you end up with vampires on the rampage. Because of the different blood chemistry's with age and sire it is hard to invent anything that works globally. Well at least that's my theory. :)
