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?
