has the same effect smoked or ingested. the reason that a lot of cancer patients ingest it is because it's not healthy to smoke and put that in their lungs. and I don't think you can test whether or not you've smoked or ingested anyway.
You cannot test how it was taken, only thc levels.
Cancer patients tend to vaporize or eat vs smoking, I am for vaporizing in that situation again just due to how unpredictable edibles are. My last edible made me hallucinate, which I was not prepared for at all, so I have sworn them off for good.
I dont agree on same effect between smoking and ingesting, it is similar but very different at the same time.
