hmm i have done lots of testing with stems and in my opinion honestly the best one to do is get a 1/5 of your favorite drink (for me its either jameson or seagrams' gin) and just put all your stems in it. Definately let it sit for alteast a week or two in a dark place. shake it up everynow and then to mix it. then once its been awhile it is forsure done soaking strain all the stems out and drink it. I cant drink it in straight shots however because it really hurts your stomach but making mixed drinks just really gets you messed up. This is what i usually do for UFC fights because one drink is enough to get you feelin real good..

ALso tea is nice but doesnt get you as high
