With the kind of tolerance I’m assuming you have you are gonna hav a hard time getting enough prepped in a shot to satisfy, I would also not recommend smoking such a small amount of oxy. Either take the time to prep right for IV which will probably take many washes and then consolidating your liquid or parachute/dissolve and drink. I don’t have to tell you that shooting pills is terrible tho I did it for a decade but if you insist please take every precaution available to you, try for a micron filter and be patient with the pills in question.
