Since clonazepam doesn't manipulate the dopamine reward pathway directly you will not experience any sort of rush from doing this besides any such russ from the physical action of using a needle. So there is no point to doing this IMHO. I would just use as it was meant to be used. Bioavailability: klonopin is rapidly and almost completely (82% - 98%) absorbed when taken orally... the absorption half life is only 24 minutes. >source<
