I actually do it very rarely lit. Such a pain getting hold of something decent, and it means associating with people that I would sooner vomit on and toss off a bridge for being..well..vermin.
Then once I HAVE it, it means heading to the batcave, and subjecting it to repeated purification steps with different solvents in order to remove all the cuts. Well...almost all. 100% pure charlie HCl is actually so hygroscopic that it will liquify in the atmosphere. So a small amount of lidocaine/glucose etc is allowable, just to have it remain a powder thats easy to handle, but anything else has to go. And oh boy..see how one's 5g shrinks:(
I'm wondering where the blazing Hades my needles, rigs and micron filters are...ordered last week, and they still are not here. Exchangesupplies.org need to hurry the bloody perdition up.
