If we inhaled a little spray of ethyl chloride, the spray the ankle, will the gas go out from your body?

Yes.: It is not very toxic. If you were to feel effects from it, the effects would be immediate- all the chlorinated hydrocarbons are central nervous system depressants like alcohol.

Depends on dose: I would not recommend inhaling this. At low doses, you might get a little "drunk "like effect, but higher concentratations it might be dangerous and it is debatable if it is carcinogenic.
