Holy crap man, DXM, Ketamine, and Datura? These are some truly terrible drugs..what effects have they given you ever since trying them? They have been proven to cause all sorts of brain damage..there's no way you can get access to any psychedelic HT2a agonists instead? The stuff you're taking would make me go absolutely insane..I would definitely stray away from that stuff..especially Datura..atropine and scopolamine are no joke. I would do Opium way before any of the other things you previously listed.
DXM put me through a 2 year psychosis, it was hell on earth for me during that time. You're in Afghanistan right now correct? Why are you there? (Just out of curiosity). Are you in the military or something?
Im studying at a american run university here... political family so I have it safe/dangerous at the same time but theres armed gaurds with AK's and my mother has 2 pistols I can ask for one but Im not a fan of having firearms, especially in the residency...
I'm at my first semester doing prerequisite courses as well as IT and Math courses, but I will probably end up focussing later on specifically on Brain biology and chemistry... who knows where I'll end up, but I plan on living here with my family and in the residency dorm till its done then go for my masters in europe somewhere, then eventually a PhD, hopefully holland but anywhere in europe, i'll be applying and travelling

...
I've only had 1 period of psychosis and it was due to MDMA/Speed abuse, almost daily, during a depression, while trying to goto college at the time, and it made try commiting suicide at the end of it....
I'm fine now, times have passed... as for other hallucinogens, I'm gonna be mushroom hunting once season starts up, its too hot atm, tho its actually raining right now and fairly cold and the weather is slowly turning... :D
Im hopefull as some of the locals as well as security gaurds I talked too told me theres tons of what they believe to be liberty caps growing around everywhere, but people don't eat them cause they are 'poisinous' or make you 'out of your mind' if eaten... (I showed them multiple pics, of different growth stages and periods, in the sun and described them...)
After hunting, Spore printing, IDing etc... ill know sure enough if there are any psilocybes out here...
Datura, that was a one time accidental thing man, A part of me wants to try making a skin lotion to have one trip but I am REALLY wearry of it...
As for the K, 1.5 G in a month isn't all that bad, that was last month, this month I did 1G, DXM, maybe once ever 2-3 weeks? and thats only been for the past 3 months...
Ever since my psychosis I try to keep my head in shape, but still get my fun..
I can also get moonshine here but its dangerous apparently but I got chill residencey mates who will be showing me around, and were its safe to buy and how to test the alcohol if the shopkeep made an impure drink... (One test he mentioned, putting sugar in a glass, and a small amount of the clear liquid, if it turns black thats not the type of alcohol you want in your system) even still, they don't like it that much as its VERY strong... trying to stick to the brand name liqour but its so far from me in the city to get haha...
Anyway, I know the dangers man

I rarely do this catagory of drugs, and datura I NEVER do other then in the past month which I used for dream enhancement... Though I hear from the afghans some of them mix hashish with datura which makes it potent as fuck for them...
I even stray from the hash here... I just like my drinks and shisha (not hash) sessions and chillaxing....
