Spit methadone isn't vomited up by anyone - who told you that, hah hah.It is where someone has to drink their script "on the premises" , so they HOLD it in their MOUTH, and then spit (see) it into a cup or other receptacle. Still pretty unsavoury, I agree, but no-one would drink someone elses vomit to get a hit or miss dose of an unsatisfactory synthetic opiate, no matter how much they're clucking (i.e. suffering cold turkey), and believe me, I know....
