Found a lot of interesting pharmacology journals with full text available.  Overseas seems to be really into alternate methods of drug delivery - transdermal etc.  I found an interesting article where they talked about the traditional ayurvedic methods of delivery of herbals via massage oils - that one involved massaging oil inpregnated with valium into a poor mouses temple.

Ayurvedic massage has some interesting techniques.  There are some oils they put in different colored bottles (ie red for this type oil and effect, blue for another one etc)  and put it sunlight for 40 days - can anyone say photochemistry?!

Here is an article for transcranial delivery of methadone
