"Marijuana Myths/Marijuana Facts" appeared in The New Republic in 1998 and in the National Review in 1999. The ad repeats five common marijuana myths and rebuts them with the facts.

Can we handle the
Truth about Marijuana?


MYTH: Marijuana is a gateway drug.

FACT: For every 104 people who have used marijuana, there is only
one regular user of cocaine and less than one heroin addict. (1)

-------------------------------

MYTH: Marijuana is addictive.

FACT: Less than one percent of people who consume marijuana do so on
a daily or near daily basis. An even smaller minority develop dependence
on marijuana. Withdrawal symptoms, if experienced at all, are mild. (2)

-------------------------------

MYTH: Marijuana lowers motivation.

FACT: For twenty five years, researchers have searched for a marijuana-
induced amotivational syndrome and have failed to find it. Of course,
people who are constantly intoxicated, no matter what the drug, are
not likely to be productive. (3)

-------------------------------

MYTH: Higher concentrations of THC make marijuana
more dangerous.

FACT: There is no possibility of a fatal overdose from smoking marijuana,
regardless of potency. High potency marijuana may be less harmful to
the lungs because people can use less to achieve the desired effects. (4)

-------------------------------

MYTH: Marijuana causes brain damage

FACT: No medical test used to determine brain damage has indicated brain
damage in humans who use marijuana - even after long-term use. (5)

So, why did we arrest 642,000 Americans
last year for marijuana offences?
