It never ceases to amaze me at what passes for research these days:
Long-term heavy users of marijuana perform significantly worse on tests of mental agility and physical dexterity than short-term users or nonusers, even when they have abstained from smoking for more than 24 hours, new research shows.
Apparently there must be some new strains of pot that invalidated all the previous, ahem, research.
Even after controlling for I.Q., other drug use, age, sex, depression and other variables, long-term users scored significantly lower than control group members and shorter-term users on tests of verbal fluency, memory and coordination.
Let me guess, more federal funding is now needed. Or maybe we should adopt the Canadian method of dealing with alcoholics and just give the stoners all the weed they need - for the children, of course.
