Sorry to hear about your friend Weezard- look up ashwaganda and Tulsi- both are aryuvedic herbs that work in conjunction with cannabis. Ashwaganda is being used in china in conjunction with chemo and radiation to repair the immune system during treatment. Shatavari and shizandra are also both herbs that target the immune system and rebuild it.
Also pure simple sugars are the best way to 'feed' the brain - by using a very concentrated green dragon with say Ornage juice- the delivery is more targeted to the brain- complex sugars ( fake ones) won't work- they must be simple sugars.
I also saw an Israeli talk about dosing of CBD, too little no effect, too much slows the effect. My thoughts are THC is phychoactive for the purpose titration- get high you hit the right dose?
I just posted some 'recipes' in another thread under concentrates using these herbs in conjunction with the green dragon ( extra concentrated) - good luck and let me know how it goes!
