An oral dose of five to twenty drops of oil taken from the seeds of wild fennel, parsley, or dill, familiar and useful kitchen spices, can provide users with hallucinations. But there are serious dangers to consider.

Those who ingest any of the three may suffer epileptic like convulsions along with their hallucinations-not much of a fun trip. In addition, while they are safe when used in normal cooking and flavoring proportions, the active ingredient that gives these plants their psychotropic kick will, because of the quantity needed, do serious damage to the user's' kidneys and liver.

Our advice: Keep away from the use of these as drugs. Otherwise, you might ruin your recipe for a long and healthy lifespan.
