What a stupid statement.
No way that marijuana in a brownie or cookie has a "more immediate effect." Quite the opposite in fact.
One feels the effects of marijuana in a pretty short time after taking a few puffs, whereas it takes a pretty long time after ingesting it to feel any effect at all. ong time.
In fact, the danger of having it in a cookie is that it takes so long to feel the effect that one keeps eating the cookies thinking that the lack of a "buzz" is due to eating inadequate amounts of cookies.
Moreover, there is a noticeable difference in the effect of marijuana depending on whether one inhales or ingests it.
Not that I'd know from personal experience, of course. But that's what I've heard . . . (cough, cough).
