Ha ha I have heard most of those.
Ecstacy sometimes contains strychnine. I found out the hard way (I was a dummy) and was a very sick girl.
Well there are a lot of things that can make you sick in Ecstasy pills.
like too much caffeine
methamphetamine
MDA if you are sensitive to it
PMA (super dangerous, ppl have died from this)
DXM, esp if mixed with MDMA or MDA (seratonin syndrome can occur from this combo)
even pure MDMA causes some ppl to hug the toilet
MDEA and Ketamine are in some pills, though unlikely to cause you to be sick
procaine and other inactive cuts are common, but pretty benign
but check out ecstasydata.org you can see no pill has ever been tested to have strychnine in it.
maybe you can even find the pill you ate there?
The most dangerous thing sometimes put in Ecstasy pills (and this is no longer as common as years ago, and mostly in Australia) is Para-Methoxy-Amphetamine (PMA). The effects of PMA somewhat resemble MDMA except the LD50 (dose at which 50% of people will kick the bucket) is only like 200%-500% higher than a recreational dose. Basically meaning its super easy to OD on the stuff, heat strokes, heart palpitations, dehydration, eventually coma.
Strychnine has no positive receational affect whatsoever at any dosage, and the pills would be unsaleable.
From Wikipedia on Strychnine:
"The onset of symptoms is 10 to 120 minutes after ingestion.[4] Symptoms include seizures, a "sawhorse" stance, and opisthotonus (rigid extension of all four limbs). Death is usually secondary to respiratory paralysis. Treatment is by detoxification using activated charcoal, pentobarbital for the symptoms, and artificial respiration for apnea."
Sorry Joc not tryin\' to school ya here, but it was once my job to know these things

if you can\'t find your pill on ecstasydata.org , tell me what your symptoms of sickness were, how it felt, it\'s usually pretty easy to figure out what was in it. peace
