save the water for when i’m out of clear (usually a month and a half to two months of semi-heavy use), then i use a pipe to hit the evaporated meth water and NOT the bong, and it effects me almost just as good as my regular clear would. then i use that water over and over and over, as much as possible. bc of this i’d try to get really really small bongs, then fill up just barely enough water for it to bubble when i hit it. i feel like water level in the bong plays a huge part in how strong the scraped crap is. i do know though that there is a great deal of meth that gets absorbed in there, not just from researching online but because i’ve done the evaporate and scrape method tons of times.
there’s no real science on why or how but i’m sure the meth vapor combined with the water vapor probably helps absorption as well as some of the effects being placebo (i.e., you see bigger clouds, so then your brain tricks you into thinking you’re getting more). I agree, whenever i’d hit the bong i swear it got me geeked as fuck off of like half of what i’d smoke via pipe. also, there’s water vapor and that’s why you usually blow bigger clouds via bong than through a pipe or foil. Click to th is water soluble, a good chunk of it gets absorbed into the water.
