Very, very unlikely: Even if there was some bad contamination, this is not likely related to cannabis. But you do need an exam. The symptoms may not all be from the same cause and you need to expect that one Dx is likely to be Anxiety - but don't just take a Rx. Fuller eval of the consciousness/language issues should be done. Seek a Health Psychotherapist to help w/ finding relief from Dr's for all of these concerns.
