The big problem with trying to make a soda is getting a wax to dissolve in water without a ton of alcohol or bromination. The dispensaries havent really figured it out yet, they try to use glycerin but this is a poor solvent and using too much makes a sudsy soda, so everything Ive seen offered is pretty weak and low potency. So Im going to let you in on a secret, on how to make high potency water tinctures, in this case soda pop. First, make some hash oil. We wont go into the how here, but it needs to be BHO, CO2, or steam distilled. Now, let us say we want to make one soda: Take one oral dose of your oil (differs for everyone, but I find 30-50mg to be great, but 100-200 mg is more painkilling), and dissolve it in an equal measure of d-limonene. limonene is a great solvent, and a 50/50 mix of hard wax oil and limonene is free flowing and thin, and is a small enough amount to ingest. limonene is GRAS, a natural component of marijuana and oranges, and tastes like oranges, so dont have any reservations about drinking it, its great. Now, take your orange smelling tablespoon or so of oil/limonene mix, throw it in a glass, add an equal amount of ethanol ( ~1tbsp - makes it no more alcoholic than sprite is, all citrus flavored sodas have ethanol in them to make the orange flavor oils dissolve in water) shot of simple syrup (sugar water), then fill with chilled club soda. You now have a glass of clear, dyeless and preservative free, 100% natural, medicated orange soda. This process can be scaled up of course, and you can use up to 5 grams of wax in a glass before you have to use enough limonene that it tastes bad to dissolve it. Limonene is widely available online, check Ama and Ebs, but be sure to get food grade. Shouldnt cost more than $10/quart, even in non bulk amounts. Dont like orange soda? you can make unflavored extract by complexing the wax in cyclodextrins - get some beta-hydroxylpropylcyclodextrin. Sounds complicated, but is a cheap sugar, about $5 a gram in small amounts. While your oil is still being extracted, after 90% of the solvent (butane or co2) has evaped off, add twice the volume in the evaporate dish of cyclodextrin, then cure/purge as you normally would,just do it for twice as long as normal. The cyclodextrin has a lipophillic interior and hydrophillic interior, and will encapsulate the oil and render it dissolveable in water. This has the added effect of making your oil more bioavailable and more ready to cross the BBB. Mix twice the amount of this treated oil as you would with untreated into your glass of club soda/ sugar/ flavor (if you choose to add flavor) The latter technique is too complicated for most, but the limonene is easy and quick and I highly recommend it (makes a tasty orange soda too). If you want a potent soda, theres no better way to go.
