       I have seen that too...  I don't get violent (I just get sick). 
However, it is a fairly well documented observation that alcohol is an 
aggression enhancer.  The term 'mean drunk' was coined from that.  It isn't a 
universal reaction.

       Actually, PCP induces chemical psychosis, and violence is very often a 
key component.  Again, like you, I'd be surprised if it happened in ALL 
samples - but it happens often enough that you can say that it is a 
characteristic associated with the drug.  I don't have any personal 
experience with it, and I really don't want to.
LP>Are you suggesting that there is a cause and effect between taking
LP>some drugs and people becoming violent, without there being any added
LP>movtivational factors (conscious or unconscious) involved?
       For some specific drugs - yes.  I have heard rumors of designer drugs 
with that specific goal in mind.  High dose
testosterone does that too.
       The effects of various drugs on the psyche are at least quantifiable.  
Pot, for instance, and on the average, tends to induce pacifism.  What you 
cannot say is that every user will experience exactly the same things (nor 
even every time).  For instance, tylenol is pretty much *useless* to me, and 
aspirin is only useful for a few days.  Hummm.... brain anatomy.  Base 
emotive center is what... the amygdala?  At any rate, the limbic system (the 
reptile portion of the brain) is significantly involved, and how YOU react 
depends on your own personal brain chemistry, and how much conscious and 
unconscious control you have over it.  In the sense that some drugs activate 
that portion strongly in some people and in others not at all just reflects 
both genetics and experiential control (nature and nurture).
       It is entirely a mistake, though, to ASSUME that violence and certain 
drugs are directly related.  A statistical picture will emerge with 
sufficient testing, as it has for alcohol.  NO, every drinker does not bash 
casual passersby, nor every angel dust head turn into Charles Manson.  As for 
Sudafed, well... that is personal.  At one point in life I became 
particularly irritated at the least little thing while taking it.  Likewise 
with the withdrawal effects of Serax (a tranquilizer).
       That is why, if you look in DSM IV or PDR, you will see a whole raft 
of side effects, many of which are contradictory.  Miz Kelly's mistake was in 
reading only the things she wanted to see.
