Can ecstasy cause flashbacks

Haha, this question made me laugh. Sometimes when I smoke with old friends we get a little nostalgic but there's never once been an incident where I completely zone out on a memory from my past. Regardless of what people say, Marijuana is a Hallucinogen, but not in the same way as LSD or Psilocybin (psychedelic mushrooms). The most frequently occurring hallucination I get is when I smoke is when feel like I'm sitting there for about 10 minutes and I look at the clock and it's been like 2 hours. Beyond that...no flashbacks...lmao!
