RCs best ROA of Isotonitazene?

[BupenOrphine]

Im an ex heroin addict of 15 years and ive been on a dose of 21 mg of subutex for a few years now, my vendor ended up sending me a free sample of iso and thust the fun began... hahah anyway... When i smoke this shit. It fucks me up(like on foil) ya, but i have to use large amounts (prob 5-10mg) and im 99% sure im destroying most of the product... what are some ROA's good for Isoton? Ive heard putting it in a regular vape works... (i have 2, my normal 2 battery one, and my backup) im thinking of putting 5-10 mg in like a 100mL bottle of juice and only smoking it out of my secondary vape... im just so sick of knowing im wasting SOOO much product the way i choose my ROA..

What are some ways you guys have figured out to do this? I want some solid advice because i dont wanna kill myself...

thanks,
bupe
