What the worse drug you have ever done?

What is the worst drug you have ever done and why did you do it? Reason why I ask is because mine wasn't 100% on purpose. I was  at a huge hotel party and I was drinking, a lot. What they didn't tell me was the Jell-O shots we laced with ectacy. So when they offered me a Molly pill I took it because I was so far gone. Than apparently I passed out because I woke up to "HURRY SNIFF SNIFF SNIFF! SOMEONE HOLD HER HEAD UP!" I sniffed on reflex and apparently did either crack or come, which ever is cheaper. Worst experience of my life. My jaw was locked at I got so desires send and was crying for my dad . This was when I was 22, now 26. Never again hardest thing I've ever done willingly is weed. If you did other drugs willingly, haeder stuff, no judgement here! I have two friends (boyfriends sisters) who are ex drug recovering addicts.
