Pharmacology - Time and Absorbency from Blotter

[n2opiates]

how long does it take for most of the active compound to be released from blotter paper when it is placed in the mouth. swim would think that most of the compound would be out of the paper (and hence into your mouth) shortly after the paper is saturated with saliva (one or two minutes). some of swims friends leave blotter in their mouths for 20 or 30 minutes, but swim has always been of the opinion that the paper can be spat out after 5 minutes or so. any info?

thanks!
