I think there may be use for smoking, it certainly has a much more drastic effect than oral consumption. But it also might have a unique effect, beyond the potency you get, per amount used.
And you can get a desired effect from eating enough of it. It is the scarcety, caused by the illegality, that pushes everybody to smoke, the small amount they manage to procure.
But I think, that not eating it, is one of the main things that facilitates abuse. I dont think you can abuse it all that badly if you follow your appetite to carefully eating it only. You of course must have very clean stuff to eat it.
I think one of the main causes of abuse, is your inner self/body/whatever, wants to eat it. But you constrain yourself to smoking it, because you have a limited amount.
But you end up, sometimes smoking more and more and more to satify that need, that is probly just to eat it. Its all burning up in front of you, and you never get to ingest that stuff you need raw and unburned up.
Think of this. You often get 'the mad eats'. You may think this is just some aberated fun, or pitfall to avoid. But,, if you were in the wild and ran into a field od marijuana, smoked some, and got the 'mad eats'. You would then eat the plants before you. I think that is the purpose of mad eats. To get some of that stuff in your stomach, in the form you need it.
You never will get the same/as much of the mental effect from eating it. But you may get something you need mire.
If you compulsively smoke. Eating some may help.
And if you use it very sparingly, you dont need to smoke it for that mental effect. But there still may be use for very infrequent smoking
You shouldnt eat anything unless you know, its clean. None of umteen bad things that could be in there that burning takes care of some of them.
I dont buy it oe anything to remain, legal. So I 'inhale' a few times a year. And so if I found a roach, I would priobly smoke it rather than eat it. But back when, I learned about eating it. I think it helped me transitin from abuse to valuable infrequent use.
