What are the worst “drugs” you’ve taken?

I’ve had a few unpleasant moments where I was expecting a drug but was given something else (or mixed with something else)<br><br>Some examples are, <br><br>Xanax pills containing fentanyl, I became extremely sick and went into a depression. It wasn’t the Xanax that did it but the fentanyl. <br><br>Another example is some guy trying to pass off meth as crack. Smoked a little bit and immediately became very sick. Muscle cramps and extreme pain, and just a euphoric feeling of a cheap stimulant. Ended up being very sick for days that time and had muscle cramps and joint pain for months. However I can assure you it wasn’t crack. <br><br>I think I’ve had K2 trying to pass itself off as weed, I went psychotic and was in handcuffs after a couple of hours. <br><br>Fentanyl in my heroin which caused me to overdose as well as black out after a couple of hours of being very sick, and having nausea for weeks after, and became depressed. The worst black out ever as I was completely comatose. <br><br>I think my worst experience was when a pill taster took some pills I got for the first time to test them while I was doing heroin, after they said they were safe, I took a little bit of the pill, and I immediately became dizzy and sick and fell over. I had the worst stomach pain and heart pain, and my heart was racing, I was having a heart attack. I was in and out of consciousness while the pill taster held my hand and talked me through it, I never thought I was going to survive, I had never felt such pain, and I was so dizzy and sick for days I was still trying to recover for weeks and still having heart pain for months. I went to the doctor and they said it was either fentanyl, benzo’s (flaum), or 3cm and I won’t say what it was but the doctor said they’ve had several patients come in with deadly heart attacks and comas from that pill. It wasn’t a good pill. I was thankfully able to escape that one. You live and you learn and you try to trust your gut feeling a little more. But I went into and out of consciousness and even when I woke up, the pain was never ending. <br><br>What are your worst drug moments like this?
