Is it safe for this person to try ecstasy...?

So, hypothetical situation: a person has smoked pot for the first few times recently. Has always been interested in trying E. This person's experience smoking pot (even only one or two hits from a bong) was not good. Basically, this person experienced an intense "dreamy" feeling (he constantly thought everything was a hallucination, even though it was not, which frightened him). This was accompanied by intense paranoia and anxiety attacks (extremely elevated heart rate accompanied by fear). The first time, this person did not handle these feelings well and reportedly "freaked out." The second and third times, although the feelings repeated themselves, this person continually assured himself that everything was real, stayed calm and took deep breaths, and waited it out. Friends reported an elevated heart beat the second time, but otherwise he only acted a little high, or very relaxed.

Friends tell him that trying a more hardcore drug - especially a hallucinogen - is probably a bad idea because he seems so prone to anxiety attacks. He seems like a "bad tripper." Is it in this person's best interests to stay away from E, because his experience with pot indicates that he will have a "bad trip"? Or would it be reasonable for this person to try E, in a very small dose, in a comfortable environment with close, sober friends?
