You cannot treat  this novel chemical structure on photo as chemical weapon but you should treat it as a research chemical (ChEIs) for medical purposes because it have medical application as research chemical. Because its ChEIs but not a poison (calling something as a POISON its so highly unprofessional primitive n00b term ). Except if your delusional black and white thinking pattern will force you to decide so ? But then this is your problem. Do your own research awith this compound and if you find it out that are truly unable  to be used for medical puposes especially for (ChEIs)(BuChE+AChE) in several molar concentration) then declare it solo as chemical weapon. So pay attention that you properly using words....

in Fiction  [CHEM INDUSTRY   vs.   FIREARM INDUSTRY lets put hands on table :D ] 

1. You can adjust dose randomly to any levels to cause total non-lethal victim incapacitation (depends of research chemical used there are in trillion various design actually unlimited posibilities)

2. You can adjust dose to cause lethal or non-lethal but long term-temporary or permanently cognitive impairment to victim (especially with irreversible ChEIs.)

3. You can adjust dose to lethal dose (depends of research chemical used)

4. Even law enforcement is not protected againist autoinjectors syringes. As they have only body armour in front. Their protection on buttock and muscle legs remains unprotected suite which is total -EPIC FAIL-  each target site of your body is fatal outcome or outcome with long term consequences. Unlike with military firearms only head or heart target is fatal or if you being shot on some site that you bleed of to death. In case If medical team emergency team dont know with what victim you being poisoned its nearly 10% of chance to save you. Keys of lock has been throwen to sea in this case. Even if emegency medical team by any luck would be able to save you you will have permanent consequences on CNS. But please note this is only one of trillion possible design ;)

5. Autoinjectors can be easily mounted on OTC crossbow or CO2 firearms or mounted even on DRONE. Which makes them extremely SILENT not as with classic firearms even with suppresors.

6. Start making full armored body suite including neck armour from some kind of polymer full body armored suite for autosyringes needles with additional front body suite bullet proof for firearms .

7.Now you can be finally your own MOSSAD agent (as they are very well known about their work and assasinations through I.M. or I.V. with various chem agents) in fiction and armed with OTC semi LEGAL(sounds familiar ?)When you will sell off your own military firearms as it no longer makes any sense except that you holding delusional fashioned designed metal parts in your hands  ? Or you still belive that firearms are more ethically acceptable or is some sort of delusional perception ? You can try to balance your mAChRs and you will quickly find it out that both are ethically unaceptable.  Well, if you shot with firearm someone in head or any other organs he can also survive and may have permanent long term consequences. But research chemicals are likely more red flagged due to its unpredictableness. Sometimes even hard to detect by forensic departments and much more expensive for analysis than with bullet with firearms. Even in some highly corrupt countries forensic insitution are highly corrupt and they simply wont revail you proper results from death. (already seen in some cases to prevent panic among society)

 8. Routes of expousure : Pulverised aerosolised fine mesh ball milled powder filled with propellant gas, injection, oral or in pyrotechnic mixute smoke granade or explosive.

9. Proposed design and dose which would be required to interfer with your neurotransmitters and AChE =  50-200 μg

Lets make some story:

Its actually abandoned hospital R&D facility asylum Neuroscience department.

Althrough department is abandoned it doesnt mean we dont make deep research within this building.

Abandoned hospital is made with reason to make a good vibe for volunters or kidnapped personels some like it some dont. But all volunters when left our facility like it more than they like it at their first impresion visit at our facility ...even when at first visit they didint like it. When our volunter left our doors they want to stay at our facility permanently. Sometimes we have to use force by our security guards. Because they simply dont want to left facility. However they cant even left the island without us. So you can imagine ?

Please note : clinic is free of charge we dont invoice you any charge of our service. Even there is no any hidden entrance fees.

Our Private clinic is un-licensed without any permits ; LIMITLESS and UNLIMITED AREA OF NEUROSCIENCE RESEARCH.

Volunters required : Most likely you will ask what reward payout you can expect. We will provide you only with 200mL of H2O(NEW SUPPLY FRESH ; UN-OPENED SEALED BOTTLE) Well, for the rest of reward : most likely you wont require it or it wouldnt make any sense after you will be released from neuroscience department.  [APPLY NOW][ONE FIELD OF THE STORIES OF THE FUTURE OF DYSTOPIA] [DO YOU SUPPORT DELIRIUM CRYPTO INDUSTRY ?
