Caffeine is a drug. We take lots of drugs. We are in the infancy of understanding many of them because we're young and because we've been prudes.Personally, I don't think it's going to be all that long before society's mental model of cannabis is fully turned on it's head from where it was 20 years ago. The dose makes the poison (or drug), after all.
Fundamentally, I see cannabinoids as less like alcohol, and more like a potential new category of vitamin. As we continue to learn more about the endocannabinoid system and build up increasing experimental evidence tying common maladies to endocannabinoid deficiencies, I see cannabinoid supplements eventually becoming as commonplace as e.g. B-complex and incorporated into mainstream multivitamins.
Going back to GP's questions:
Is there a way to microdose? I'd like to be able to have tiny, controlled amounts every time.
Tinctures/oils. Sublingual absorption is the next best thing to pulmonary absorption in terms of efficiency, but it won't cause long-term damage as inhaling hot ashes and gases might, and it'll allow you to measure the dose down to the mg.
Is there a solution to munchies?
Speaking for myself, I've been microdosing 200mg of Sunsoil full-spectrum CBD oil and 50mg of 3Chi delta-8-THC oil first thing in the morning and before bed since around the end of April.
This helps with both my sleep quality/consistency and preventing semi-regular headaches that had been causing an unhealthy reliance on NSAIDs. It doesn't cause a high or any noticeable psychoactive effect.
However, rather than "munchies", it's actually significantly reduced my appetite. Without any other deliberate change to my routine, such as calorie counting/restriction, I've dropped from 210 to 186 over the past 2.5 months with no perceptible loss in muscle strength or mass, and so far see no signs of the trend stopping before I reach my goal BF%. (I use the term "deliberate" because, although I am currently only eating one meal per day around lunch - dinner time, it isn't an intentional IF/OMAD schedule; it's just the current limit of my appetite.)
That being said, I can't definitively attribute this effect to a particular compound. It could be the delta8, it could be the CBD, it could be a different cannabinoid, it could be the interactions between some or all of them, it could be the 200 calories of MCT oil that I'm now ingesting each day (on top of what I was already taking separately pre-workout), and/or it could be the interactions of any or all of the above with the fact that I've been keto for over nine years. YMMV.
