I think E is fine...

We are comaring 20%, a number,

in D those is comparing adults rather than the number...

Ritesh:
could you elaborate more?
I was really stuck on this, btw D & E, I thnk the number of drug users increased so thats what we are comparing, in E it just says "a" number increased...

I would really like a good discussion on this topic..

According to surveys by the National Institute on Drug Abuse, about 20 percent of young adults used cocaine in 1979, doubling those reported in the 1977 survey.
(D) twice as much as those reported in the 1977 survey
(E) twice the number reported in the 1977 survey

if you break D, it looks something like this..
twice as much as those (adults) reported in the 1977 survey.

I think sentence is more fluid with THE NUMBER, since the number seems to indicate the 20% percent correctly...

As much as is used for non-count noun but here the noun, adults, is count-noun so go with number in E.

Percentages are tricky. We aren`t given a concrete number of countable adults so I`ll have to go with D.
