Beer leaves the system in days and is far different from the psychotropic effects of THC of pot. Just as the man who killed his wife from eating pot cookies, just as the suicide kid who jumped to his death after eating pot laced cookies, just ask the rapper for the Woo tang clan.
Red Herrings are for fishing not smoking in a bong. (then again the pot heads smoked banana peals in the late 1960s)
The psychotropic effects of THC end within a few hours with vaping or smoking and within about 12-16 hours with oral ingestion. Detectable MJ metabolites exist for longer, but aren't psychoactive.

The high doses in edibles are a real problem. They should be cut by at least 75% per item. This should be regulated just as is beer %alcohol, etc.
One good thing about MJ is that a user tends to "never do that again" after getting too high a dose. Very different from alcohol, where the dose over time tends to go higher even after a bad experience (except for me, I threw up once and quit forever)
