Interesting! Will have a read when i get time
I have noticed somewhat of a link between heavy substance abuse and some SK's, and in some cases its been their downfall. (Abuse gets worse which makes them sloppier and ends up with them being caught)
All good bud. I've been a drug user(Everything and Anything - I like trying new experiences) for about 10 years now with absolutely no addictions. I've been around the "party" scene for an equal amount of time so i've come across all forms of users for recreational businessman to full blown junkies living in a squats.
Here's a little story for you...Back in my teenage years i went to a party in gnangara pine plantation. A friend whipped out a baggie halfway through the night and we all talk turns having a few lines. Throughout the night, i had this overwhelming sense that i was being watched through the trees. I kept seeing movement in my peripheral vision..but it was only enough to make me go "...what was that?", i heard gravel being walked on behind me multiple times too.
My friends heard and saw none of it. I've never had any sort of paranoia from drugs except from this night, so i put it down to circumstances of being in a creepy ****ing forrest. My point being - These types of circumstances makes emotions/feelings and thoughts unpredictable and harder to deal with. Another good example is that a friend of mine once lost his car keys at a party, he proceeded to rage out and lash out at everyone over stupid **** until he found his keys, then proceeded to profusely apologise to everyone. Normally, he's a really chill dude. Get him on speed and he gets easily agitated. Never got violent, but just couldn't control his emotions properly.
Could you imagine having to deal with murdering someone, hiding the body, covering up the evidence while dealing with paranoia and heightened emotions like that? I couldn't do it, it would make it so much harder than the situation would need to be.
Who knows, you could be totally right, he could be one of the few people who get very little negative side effects, but from my experience in life its doubtful. I just really, really cannot see this guy as an amphetamine user.
