Even worse is are the conditions for being prescribed. First you have to have failed 5 previous medications but still be taking one. The dosages are delivered only to your psychiatrist. You have to have it injected there and then you have to wait 2 hours and are not permitted to drive for 24 hours. And that's for the several injections per week...
So not only will the drug be expensive but you're going to be charged a doctors visit every time AND you'll have to figure out how to get off from work for hours each week.
Seems a lot easier to go down to the local high school and buy a bag of K.
