It is only slightly soluble in alcohol...
But you can shoot Klonopin by dissolving the tab in 0,9mL water + 0,1mL alcohol, filtering with micron filter
BUT:
-shooting Klonopin is completely useless: the effects will be exactly the same than the effects you get when you eat it; shooting it produces no rush, it will only kick in faster (less than 5 minutes)
-shooting pills is very dangerous, much more dangerous than shooting any other drug...
It's not worth taking the risk to shoot a pill when you will only get exactly the same effects, just a bit faster...
But it is possible, if that's your question...
