actually prefers anywhere from 80mg to 160mg either snorted or parachuted (after pill has been crushed). SWIM would not recommend others taking this dosage unless they are very opiate tolerant.
One mentioned starting @ 10mg merely because he does not know SWIyour opiate tolerance level. There are 2 kinds of this opiate tolerance level.
1] natural tolerance: When the body naturally has a fairly good tolerance to opiates
and low recreational dosages only give medicinal relief rather than a recreational effect.
2] acquired tolerance: when a type or group of a specific drug
is taken for long enough and ones body has developed a tolerance to the substance type.
Parachuting is when SWIyou put the crushed powder into a "Rollie" or cigarette paper and drop it like a pill. Alternatively SWIMs monkey has also had some very good results just putting the resulting powder under his tongue (although he says it doesn't taste good).
Hope this has been of help.
