Edible cannabis is completely different then smoking, or vaporing. The reaction is much slower and lasts much longer, The reason for this is when you ingest cannabis your body process the THC in the Liver which turns it into a new chemichal you body knows exactly what to do with, and has been waiting for.
“In a nutshell, eaten cannabis gets metabolized by the liver, so delta-9 THC becomes 11-hydroxy-THC, which passes the blood-brain barrier more rapidly and has more of a psychedelic effect than standard THC,” says Understanding Marijuana author Mitch Earleywine, a professor of psychology at the State University of New York at Albany. “Smoked or vaporized cannabis bypasses the liver and doesn’t create the same 11-hydroxy-THC.”
You can purchase edibles from reputable places, or you can make your own edibles. I can teach you various methods of extracting the THC into edible forms, I can also monitor you while you take them to provide a safe environment for adapting to something new.
