What are the effects of snorting my prescription drugs over having to take them by mouth. When I take them by mouth I feel like a zombie and am always falling asleep. When I snort them I find they don't effect me the same way as by mouth because I am splitting them up during the whole day and night. Does it damage your lungs when you do this? Since I have to take these pills for chronic pain I just hate feeling so out of it all the time when I take them by mouth. They still take the edge off my pain, but I am not as adversly affected by snorting them.
