My friend recently smoked something she believed to be marijuana, but after doing so, her heart rate went from 68bpm to 246 bpm for approx. 15 min. She says the muscles in her eyes went numb, as did the feeling in her extremeties,& she experienced tingling/stinging in her chest. She also lost feeling in her throat & her speech was limited,with much stammering & pauses. She says she had smoked marijuana before & believes there was something else in there, but she has no idea what because she has never willingly done any "hard" drugs. Five days later the back of her throat is still numb & she has trouble swallowing when she's not eating. (She can chew & swallow food but just swallowing saliva is taxing.) She also has trouble yawning, concentrating & comprehending written material & believes her speech is not as fluent as before; she has longer pauses, stammers, and mispronounces/misspells words. She's tired at strange times throughout the day & then cannot fall asleep at night & no longer feels hungry; she just eats at seemingly appropriate times. At random times throughout the day her left hand tingles & sometimes feels very hot; this happens frequently when she tries to fall asleep. She is 20 years old & in pretty decent health. She's 5'10" & weighs 165 pounds & the only medication she takes is Ortho-Tri-Cyclin. Is it possible she had a stroke or is she just "worked up" after her incident? Is there any way to tell without going to a hospital and getting some sort of brain scan? She is genuinely concerned and would appreciate any feedback. Thanks you.
