Does it matter how much water you use? Theoretically, the more of that looted the solution is, the weaker the effects will be.
Of course, due to the stronger High, you want to start off with a very small amount of cocaine slightly increase dosage until you find your sweet spot.
My scale only goes as low as a tenth of a gram, not milligrams. How much do you want to start off with? A normal key bump, half of a key bump, smaller? If I decided to try this method, I would like to avoid such a small amount of cocaine that the high was quite week. It would be almost like a waste of cocaine. At the same time, I understand starting off with a low dosage and is safer then doing too much until you figure out what works best for you.
Correct me if I'm wrong but isn't the high from putting cocaine similar to that of smoking crack? An intense high that only lasts about 5 or so minutes? I guess it would be safer to assume that the more intense and short-lived high would caus you to want to redose sooner and more often compared to snorting cocaine.
