Can you crush morphine and smoke it to get high?

yes because crushing a liquid is physically possible. If you get morphine pills, it will have an immediate effect. Make sure you have the right dosages though because you could OD easily. The dosages people report snorting are in the 5-30mg range and the dose people have reported smoking is more in the 3-10mg range. Morphine is highly addictive even more so than weed so be careful because you can get hooked after 3-4 times.
