I hear ya about plugging.
You can catch teh gai plugging 30's!
No seriously
You can get REALLY HIGH from plugging if ya do it right. I've never plugged oxy but I have plugged
Avinza's. (MORPHINE)
I crushed up the powder really well and put it in an ORAL SYRINGE. I mixed in a bit of water and shook it for a while.
I used a ton of lubricant slid it in and pulled the trigger.
Next I put my legs up in the air lying on my back using the couch for support.
Nice RUSH!!! I may be due for another try soon!!!
Besides IV plugging gets ya the highest IMO
