When marijuana is eaten, it takes longer to notice an effect, and the effects last longer. In one experiment, the drug effects did not start until 30 minutes after the marijuana was eaten.
Persons eating marijuana often take too much of the drug.
It takes so long for the desired effects to occur, that users may think more is needed for the high and accidentally use too much. Smoked marijuana and oral THC produce similar effects.
