Yes for this chemical extreme caution is necessary, this is what happened to me :-.)(*"

:")£(
Received 2G THJ 2201 , 500 mg MMB-CHMINACA, I went through the 2 grams in say 2-3 days of thj2201 and i recommend this drug out of all the cannibinoids it's perfect, you can be pretty liberal with your doses (without scales) i have purchased it many times and have never had issues eyeballing. After i finished the thj i opened the MMB and i did do some research, like this is the most powerful drug i've ever done and i was expecting it to be however, in my screwed up lil high mind i just put a bit less in than i had been doing prior and i gained consciousness in an ambulance outside my house, i think i was being violent ........ (against my nature) cause i got the feeling that the people in the ambulance with me were having a hard time, anyways i then threatened the guy to let me off the ambulance and i went back to bed only to wake up naked on the floor being handcuffed and taken to hospital. Interesting to note despite being incredibly drugged out of my face i managed to hide the MMB in my boxers the entire day.
I get home...... that was very stressful i said, i think i need a JOINT after that.............. regained consciousness in hospital in the same day LOL, i even made extra special care to like 1/3rd my dose honestly you could barely tell there was a substance in my cigarette. Got home, and .......... had another joint the ambulance was called again.
This is really not normal for me and i can't explain to you why i kept doing this to myself but understand i rarely ever touch drugs maybe once a year i'll get "drug urges" and order some RC'S that's all.
Anyways i order the same a week later after doing more research and i was hospitalised for the 3rd time after the 2 grams of thj, when i hot home.
I was putting in THREE specs of the finest powder at the end of a cigarette and finally managed to just relax and get high but you know what? I prefer the high THJ2201 has over this, because this stuff is more like "indica" and will put you to sleep, tjh2201 is much more mentally altering.
In conclusion even if you know your amounts and are measuring volumetrically - you don't know how this will effect you just leave it, and buy thj2201 which is cheaper and nicer.
