Are you sure your question is about not getting high? It seems it may be about not getting stoned. Vaping will definitely produce more of a cerebral clear high, and smoking (the same exact bud) will produce a more sedating cloudy stone. Vaping keeps out a lot of CBD, which is mostly responsible for the sedation of smoking, and also the combustion products like CO and CO2.
Make sure it is at the right temperature, and inhale SLOWLY. If this does not get you the desired effect, then either your weed is crappy, or you are too used to the junk that smoking puts in your body. At any rate, the vape will be a lot healthier, and will leave you more functional if done properly.
