Get medicine dropper put a piece of cotton in bottom of it, run water or 90 proof alcohol through it so it stays compressed and bottom of medicine dropper. Hold finger on bottom fill it with 90% proof alcohol not to the rim but enough so pill will dissolve, then drop pill in and let it dissolve. Wait about 2-3 mins the put the plunger in and push then push the liquid through the cotton into a spoon or can. The set on fire and let all the alchol cook off. (Has to be 90 proof only can?t use the other one) then your dope will be left. Hit it with water and pull it up into your syringe and there ya go!
^ that sounds incredibly dangerous if you're not micron filtering.
injecting pills is extremely damaging with normal pills without these crazy modern 'abuse proof' tablet formulations.
if you are going to attempt something like this, using a micron filter is essential.
a micron filter (or “wheel” filter) attaches to the top of your syringe using the luer lock. They come in different filtration pore sizes, with .22 and .45 microns being probably the most common. They are essential if you are determined to inject pills.
This might not be what you're looking for, but shooting abuse proof pills isn't too great of an idea, what my cichlid would suggest is dropping it in soda such as coke (high acidity) and letting sit for 12-24 hours depending on the design of the pills release mechanism, and shake occasionally to equally distribute the opana and having a relatively safe volumetric measure and be able to drink it. It might not be what you're looking for but hey its an idea ?\_(ツ)_/?
