How low of them to use the test in SWIY's house for sewer-gas as a guise for unknowingly testing SWIY's house for drug extraction-related solvents.
The Machine goes a step further in breaking into and controlling our private lives every day.
Luckily mother nature gave us orange peels.
Nature provides and preserves us.
The only thing SWIM's concerned about is that this forum is probably closely watched by the leaders of the modern pharmacological inquisition.
Everything SPWAU(Some People Who Aren't Us...lolz) find out to dodge their tyrany and proceed making and sharing enlightening and spiritually unblinding substances, they (The inquisitive tyrants that rule us.) will find out very soon too.
D-limonene seems preferable to other solvents, because of it's health-safety as well as because of it's poor detectability.
SWIM wonders: Is it easily/cheaply obtained? SWIM recalls once reading that D-limonene could simply be extracted in a lengthy hot-water infusion of powdered orange peels. If that were true then only evaporation could separate the D-limonene from the water. Is it that simple indeed?
If it is indeed that easy to obtain then it isn't only much safer(Health AND Law-wise) than other solvents, but also incredibly cheap, then SWIM is jumping to D-limonene his very next spice-extraction.
