I have tried various comedown aids (to various substances that have comedowns, of course ) and in his opinion kratom is the best he's found for just about everything (so far). * It has a stimulating component combined with opiate-like effects, which is perfect to soften the landing from any stimulant. Provides a "second wind" effect along with psychological cushioning, and substantially elevates mood as well. * It isn't so strong as to begin another powerful "high" in itself, nor is its dependency potential really high like most benzos and opiates. Although dependency is possible, it takes weeks/months of regular use to develop, and withdrawals are neither intense nor protracted (SWIM's personal experience). * It has never presented a problem to I used while the main substance is still active, i.e. allowing the main substance to wear off completely appears to be relatively unimportant. Nor has it had negative cardiovascular effects, like those I have noted with marijuana used shortly after heart stressing stimulants. I recommend this herb highly to anyone still searching for the perfect comedown aid to their favorite substance. Hypothetically speaking, of course. "Commercial grade" Bali leaf in a ground/powdered form is recommended for the full spectrum of effects, rather than an extract product. Approx. 10g packed into capsules or made into a tea should be about right for the average person.
