****D'Souza and his co-researchers administered various doses of delta-9-THC, the main active ingredient in cannabis, to subjects who were screened for any vulnerability to schizophrenia. Some subjects developed symptoms resembling those of schizophrenia that lasted approximately one half hour to one hour.*****

Honestly i do not think any pyschoactive is going to have a postive effects on someone with vulnerability to schizophrenia.....fuckin yale assholes.

****The principal active ingredient in marijuana causes transient schizophrenia-like symptoms ranging from suspiciousness and delusions to impairments in memory and attention, according to a Yale research study.****

transient schizophrenic symptoms like suspiciousness,delusions and impairments in memory...wtf! those are symptoms ANY pot smoker under ANY condition could display.I see all of those symptoms in certain people i know,and they have no mental dis-abilities.Attention span?! come the fuck on,i just forgot what this post was about for like 5 seconds,and im not schizophrenic...bottom line...those symptoms are not just in a % of shizos who blaze,they are in a % of EVERYONE that blazes.

****These symptoms included suspiciousness, unusual thoughts, paranoia, thought disorder, blunted affect, reduced spontaneity, reduced interaction with the interviewer, and problems with memory and attention. THC also induced euphoria and increased levels of the stress hormone cortisol. There were no side effects in the study participants one, three and six months after the study.****

again, all those symptoms are not restriced to the mentally handicapped. REduced spontaneity?!?! wha tthe fuck is that,how bout fuck you yale cock-suckers for reduced spontaneity. Reduced interaction with interviewer....maybe cuz they are asking so many dumb fuckin questions?But they do have one symptom right....blunted affect...i found that funny.
