Where can I find information on the relationship between drugs and Islam?

I’m writing a research paper for my history of Islam class about the use of psychoactive substances in Islam, but I’m having trouble locating scholarly sources.

Topics I intend to cover are:

-The Qur’an and alcohol
-Sufis and the use of hashish and caffeine
-The opium trade in Afghanistan
-Modern attitudes towards drugs in the Muslim community and rates of use

Any help would be greatly appreciated. Also, additional suggestions for points to research would be appreciated as well.
