a few grams of acetylated morphine need to be cut.
even if because of the sole reason cos shit is dangerously potent.

thinking the following:
diphenhydramine hcl, tizanidine, caffeine, brown sugar (sucrose).
dissolve in methanol, filter, recrystallize, let to dry.
then add the smack to the powder and do the same.

how does that sound?

Cutting drugs without making people aware is immoral. The possible exception of heroin because people expect it to be cut and pure heroin is therefore dangerous. Cutting things for potency is dangerous because there's no guarantee that it will be evenly distributed. If you can't measure accurately, your best bet is to make a liquid solution and then either take it directly or evaporate it onto something.

However, a new layer of danger is added when you're adding substances that have their own effects, especially on systems that differ from the main drug. People may be mixing substances, or they may be on prescription medication, and unknowingly taking other substances could be potentially dangerous or even fatal. Like metamorphin said, a sugar like mannitol would be cheap, safe, and inert.

Not trying to lecture you if it's for personal use, just trying to be direct because it's easy to die doing this sort of thing.

Never fucked with heroin myself, but afoaf  used to sells black tar, and cut his shit  with instant coffee and an oven or high powered lights .  Watched an ounce turn into three many times.  Doubt this would be responsible though.  It does mean that my dream of a coffee fed IV drip could be possible.

Try harder....

This is one of the few examples where I would allow discussion of a cut due to the deadly nature of pure substance but even the opening post is just laid out in a lazy fashion so I am not going to allow this to progress any further.
