Ross

I believe the answer is:

coke

I'm a little stuck... Click here to teach me more about this clue!

This might be a double definition.

'fuel familiar' is the first definition.
'coke' can be an answer for 'fuel' (I've seen this before). I am not certain of the 'familiar' bit.

'a drug' is the second definition.
(cocaine)

'as' acts as a link.

Can you help me to learn more?

(Other definitions for coke that I've seen before include "Furnace fuel" , "Solid fuel - drink - drug" , "Drink - drug - solid-fuel product" , "Substance left after gas and tar have been extracted from coal" , "A solid fuel; a drug (abbr.)" .)
