Crispnchuey, E is a huge stimulant as it is, he in no way will need any more in his system, doing so would probably just send him haywire.
As for getting stoned, it depends on his choice, if he wants to hullicinate (which is fun, because your so damned happy) then he should smoke some gear, if he wants to party, then don't smoke any.
Acid and E, damned great choice though
