As is typical of marijuana scaremongers, Jack Falk misconstrues the fact that marijuana metabolites are detectable in the body for a longer period than alcohol. The effects of marijuana (the high, if you will), however, are fairly short-lived (two to three hours if smoked, six to 12 hours if ingested). The letter writer needs to educate himself a little before making such easily repudiated claims. Ted Tarrant, Calgary - --- MAP posted-by: Matt
