Is my room mate schizophrenic?

Not even close to schizi. Just a very weird night. She probably was high on weed, drunk, and high on something else like a hallucinogen (LSD or magic mushrooms). A combo of all these drugs is obviously a dangerous thing for your body and can have effects that last for days, weeks, months, sometimes, depending on the amount, for years. But this isn't even close to the signs for a person to be schizophrenic, just watch out for her.
