First off, the kid that posted this tread didn't even site his article, it looked really immature like he had no clue what he was talking about, he posted it because "He thought it was funny" then he lapse into some retarded slang and you just wish you were around to see this kid and smack him in the back of the head.
2nd, welcome to the internet. 2 second of google.

If you care to read any of the Blogs at the bottom of the page there are some pretty powerful testimony's to the dangers of drugs.
I will admit that I created my list above ^ after considering for only a couple of second what I thought the biggest risks were, I do speak from experience with some of the drugs for mentioned, I will also state it took me having to leave Whistler and go to Rehab for a 4 month cycle & I am now almost a One Year Clean & Sober. I attend A.A groups/NA groups every week, and will have to do so for the rest of my life. I don't care if you use drugs if that's how you want to live, I choose to change my ways. I'm enrolled in College to start this Spring.
Everything with respects to Drug Usage is Relative. My worst Drug of choice happened to be Alcohol which HAPPENS TO BE LEGAL. Problems would arise when I'd get drunk, and wake up with an empty bank account. You Dig?
Everyone is Different when it comes to drugs, and Most addicts have concurrent disorders even if it doesn't surface until your in the depths of an addiction. Someone could have a bad trip on Acid and go HelterSKelter on his best friend, Some other guy might get shot in the face over an eightball that was short, some girl might get raped because she was blacked out drunk with a drink spiked with some GHB, Some kid might smoke up his first time think he's god, Some kid might do a line at a party and realize after snoring it up it wasn't cocaine.
So go talk shit, everybody has there own story to tell. You might be straightedge, your mother might be a drunk, your sister might become a prostitute to support her meth addiction.
Theres no such thing as a list of the most dangerous drugs. Just stupid kids that want to grow up to fast on the internet.
