Any explanation for why I got so high??

Today I had one energy drink earlier in the day maybe 4-5 hours before smoking and also took my antidepressant Cipralex (which I've been on for quite a while now) at the same time as smoking. I've smoked lots before and smoked the same hash that I've used lots before and i don't think I smoked any more than I have multiple times in the past but this time I got super high with a major anxiety attack that peaked 1 and a half hours after smoking when it usually peaks after 30min for me. Also took 0.5mg Xanax when I felt things where going wrong but even that didn't help?

I'm kinda just confused by the entire thing and wondering if anyone can explain it???
