The "True Lies" and their "truth" are in Italics. )

1. Marijuana isn’t as strong as it used to be.
Truth: Since the marijuana available nowadays is over 500 percent more powerful than it was ten years ago, the dangers of smoking marijuana are much more serious than they were in the 1960s.
(Marijuananews note: Number one is a classic "straw man." I don’t know of anyone who claims that "marijuana isn’t as strong as it used to be." However, the opposite claim, which is the "True Lies" answer, has become a staple of prohibitionist propaganda.

According to the US government sponsored Potency Monitoring Project, the only source of data on the potency of marijuana in DEAland, the average potency in 1989 was 2.66%. The National Institute On Drug Abuse says that average potency today is around 3%. According to official tests in the Netherlands, the average potency of marijuana there is around 8%.

Moreover, there is no data on potency from the 1960s, and there is no reason to believe that more potent marijuana is more dangerous.)

2. Marijuana is better for you than smoking tobacco cigarettes.
Truth: Marijuana smoke causes cancer more than cigarette smoke. In fact, because marijuana smokers try to hold the smoke in their lungs as long as possible, one marijuana cigarette can be as damaging to the lungs as four tobacco cigarettes
(Marijuananews note: Of course, there is no data proving that marijuana has caused cancer. Second, the risk in both tobacco and marijuana is dose related and most tobacco users consume far more smoke than marijuana smokers. How long marijuana smokers hold the smoke in their lungs is an artifact of marijuana prohibition, not a characteristic of the plant.)

3. Since marijuana grows from the ground, it must be natural.
Truth: There are more than 400 chemicals in the average marijuana plant.
(Marijuananews note: This is not really an answer, but in any case, coffee and orange juice, like most plants have hundreds of chemicals. A more straightforward answer would be that there are many highly toxic plants, like tobacco, so being natural doesn’t prove anything about safety, but they seem incapable of being straightforward.)

4. Marijuana stays in your body for less than 24 hours.
Truth: The active chemical in marijuana can stay in the body 14 days after smoking a joint. Even after a person has stopped smoking, the marijuana stays in their body and can still affect their ability to do things like drive, play sports, or do well on tests in school.
(Marijuananews note: Completely wrong. It is the metabolites of marijuana that stay in the body, not the "active chemical." Amazingly, elsewhere on the same site one will find:
"THC in marijuana is strongly absorbed by fatty tissues in various organs. Generally, traces (metabolites) of THC can be detected by standard urine testing methods several days after a smoking session. However, in heavy chronic users, traces can sometimes be detected for weeks after they have stopped using marijuana."

Of course, vitamin E also is stored in the body for a long time.)

6. Marijuana is not addictive.
Truth: Experts are not yet sure if marijuana is addictive, but they are sure that some marijuana users develop something called "amotivation syndrome." People who develop this disorder become extremely lazy, unmotivated, and they lose interest in things they used to enjoy.
(Marijuananews note: It would have been so much better to tell the truth. Marijuana is not physically addictive, but some people, especially young people who use it inappropriately to cope with their problems, may become dependent on it. The "amotivational syndrome" is a left-over from the 1960s version of reefer madness. Kids can see that many of their peers use marijuana and are not "amotivated.")

7. Almost all teenagers use marijuana.
Truth: Four out of five teens do not use the drug and most teens disapprove of using drugs.
(Marijuananews note: True enough, but notice the switch from marijuana to "drugs.")

8. If you only buy drugs from friends, you will get the pure stuff.
Truth: Illegal drugs are often messed with on the street. No one can know what is really in them. For example, marijuana can be laced with PCP.
(Marijuananews note: True enough, but this is an argument against marijuana prohibition. How often is beer adulterated? Marijuana is less likely to be adulterated than any other illegal drug, but the only example of adulteration that they give is for marijuana.)

9. You have to use drugs for a long time before they can really hurt you.
Truth: Drugs can cause the brain to send the wrong signals to the body. This can make a person stop breathing, have a heart attack, or go into a coma. This can happen the first time a drug is used.
(Marijuananews note: Again, true enough, but not about marijuana. Marijuana is almost the only drug that cannot cause a fatal reaction. Eight of the ten questions are about marijuana. None are about alcohol or prescription drugs.)

10. Inhalants are not risky to use.
Truth: Using inhalants even one time can put you at risk of sudden death or suffocation. Prolonged use can lead to nose bleeds or liver, lung, or kidney disease. Inhalants can also cause brain damage.
(Marijuananews note: Completely true, but after they have lied to the kids on all the items about marijuana, is it surprising that they won’t be believed when they tell the truth about inhalants? The most recent survey of teen "drug" use in California showed that more kids were using inhalants than marijuana. Nonetheless, 80% of the space on this page is devoted to lying about marijuana. This is truly "sending the wrong message.")
