1-A 16-year-old male with a long record of arrests for breaking and

room with a plastic bag on his head. For several months he had been experiencing

and mydriasis. Which of the following substances did she most
likely ingest?

1- A: the most important thing here is the neurological signs, inhalants are known to cause peripheral neuritis, cerebellar signs, deafness.. and even permanent cognitive impairments!

2-E!! thats the given answer!! i also went for ecstasy! but its wrong, and thats the explanation, although i didnt find it very useful: Patients ingesting LSD may
have a wide variety of sensory disturbances, and because of the sympathomimetic
effects of the drug, may experience tremors, hypertension, tachycardia,
mydriasis, hyperthermia, sweating, and blurry vision. Patients may
die when they act on their false perceptions (in this case, the belief that the
patient can fly) or accidentally kill themselves. When the subject is not
clear about which drug was taken, the unexpected sensory disturbances
can be quite terrifying, and patients can fear losing their minds, as in this
case.

3- A!

about q 2, not sure if this is really important, but a specific sign of ecstasy intoxication is bruxism!

LSD causes sympathetic hyperactivity, as do Amphetamines and cocaine... ecstasy, which (to my knowledge) is a derivative of amphetamine will also do that! so they all share the sympathetic hyperactivity symptoms.. so here are some specific intoxication signs that i wrote on my notes to differentiate:

cocaine and amphetamines: Formication hallucinations (snakes and insects on skin)
LSD: wilder type of hallucinations (visual, auditory and tactile) in addition to flashbacks
MDMA: bruxism!

and by the way, both LSD/amphetamine/cocaine produce mydriasis, not sure about MDMA!

anyone else with more ideas about differentiating those intoxication syndromes?
