What over the counter chemical can knock someone out?

Answer 1

propofol, pentothal, methohexital, etomidate or ketamine. (10-30 seconds)

Large doses of opioids will also render someone unconscious

Ketamine can also be given IM.

Inhalation (takes longer than 5 seconds, more like 2-5 minutes): Sevoflurane, isoflurane, desflurane or the older gases, like halothane, enflurane, cyclopropane or ether

Answer 2

This is the same guy that asked "How do you make a chemical to unconscious someone." This was my response:

To unconscious someone? I am going to start using adjectives as verbs too. I am going to thirsty some milk. OK, so... here is how I feel about the question. If you do not have the grammatical skills to ask this question correctly, you cannot be trusted to follow a lab procedure, nor can your motives for asking the question be trusted either. In both cases I am reluctant to answer the question. But I am going to give you a step by step process for the creation of a chemical to unconscious some one.

1) Take a bunch of corn or fruit and throw it into a big pot. Add lots of sugar and some bread and a couple packets of yeast.

2) Let that sit for a few days and then cook it for a while real slow and not hot enough to boil for a few hours.

3) Distill (fractional distilling works well and quickly if you have the lab for it) at about 177-180 degrees.

4) collect the distillate

5) give to victim in glass mason jar

6) sit back and wait.

Answer 3

melatonin is the closest to being able to paralyze someone.

Answer 4

Chlorine, Ammonia, Methylphenidate (Prescribed to those with ADD/ADHD), any type of chemical which smells like its not meant to be inhaled really.

Answer 5

Any chemical that could knock someone out could also potentially hurt them. Chloroform is in many household cleaning products but I wouldn't risk injury to another person.

Answer 6

Chloroform can be used
