Is if more effective to snort methadone?

NO. Do NOT snort methadone. You will regret it if you do. It burns very bad, and also is pointless as well. Methadone is a SLOW acting opioid and will not produce a euphoric effect any faster by snorting it. Also, methadone expands the second it touches moisture. If you do not believe me, put one in a cup of water and watch. It will get stuck in your nose.
