Why wouldn't just a wash with dry acetone and filter. Seems easer and effective....
As far as chemistry taking place for shorting a buzz, What happens is the MSM helps your body do its thing better... It's thing is getting rid of foreign substances like meth. It helps your body clean itself better.. MsM used to be part of our diet before food processing got ramped.. It is elusive to food processing, even over cooking veges will move it away from our pallet.... It starts out being evaped from oceans and as it gets into the atmosphere uv rays turn it into Methyl solfonel methane and it is carried by rain back into our food supply.. In the old days our body's got its natural supply this way but today it is lacking in our diets... If one was wanting to quit using meth I would recommend two heaping teaspoons a day in OJ, once in the morning and again in the after noon for a week then back down to one table spoon a day... You will be surprised that after a week your tossing and turing in bed at night instead of the typical no ambition feeling one gets without his gogo.. It is in health food stores but is not pure and is expensive, 1000mg pill usually has mag. sulfate or another preservative and or vitamin C added to it. The best place to get it is at your feed and seed stores because 2.2 lbs is around 14 bucks US and it's 99.9% pure, comes in a jar instead of jell caps... Horses get better shit than humans do because they cost more..
