A marijuana user may experience pleasant sensations, colors and sounds may seem more intense, and time appears to pass very slowly. The user's mouth feels dry, and he or she may suddenly become very hungry and thirsty. His or her hands may tremble and grow cold. The euphoria passes after awhile, and then the user may feel sleepy or depressed. Occasionally, marijuana use produces anxiety, fear, distrust, or panic.
Heavy marijuana use impairs a person's ability to form memories, recall events and shift attention from one thing to another.8,33 THC also disrupts coordination and balance by binding to receptors in the cerebellum and basal ganglia, parts of the brain that regulate balance, posture, coordination of movement, and reaction time.11 Through its effects on the brain and body, marijuana intoxication can cause accidents. Studies show that approximately 6 to 11 percent of fatal accident victims test positive for THC. In many of these cases, alcohol is detected as well.34, 35, 36
Persistent (lasting longer than intoxication, but may not be permanent)
- Impairs short-term memory
- Impairs attention, judgment, and other cognitive functions
- Impairs coordination and balance
- Increases heart rate
Long-term (cumulative, potentially permanent effects of chronic abuse)
- Impairs memory and learning skills
- Can lead to addiction****
- Increases risk of chronic cough, bronchitis, and emphysema
- Increases risk of cancer of the head, neck, and lungs
Is marijuana use addictive?
Long-term marijuana use can lead to addiction for some people; that is, they use the drug compulsively even though it often interferes with family, school, work, and recreational activities. According to the 2003 National Survey on Drug Use and Health (NSDUH), an estimated 21.6 million Americans aged 12 or older were ****fied with substance dependence or abuse (9.1 percent of the total population). Of the estimated 6.9 million Americans ****fied with dependence on or abuse of illicit drugs, 4.2 million were dependent on or abused marijuana.57 In 2002, 15 percent of people entering drug abuse treatment programs reported that marijuana was their primary drug of abuse.58
Along with craving, withdrawal symptoms can make it hard for long-term marijuana smokers to stop using the drug.49 People trying to quit report irritability, difficulty sleeping, and anxiety.59,60 They also display increased aggression on psychological tests, peaking approximately 1 week after they last used the drug.61
In addition to its addictive liability, research indicates that early exposure to marijuana can increase the likelihood of a lifetime of subsequent drug problems. A recent study of over 300 fraternal and identical twin pairs, who differed on whether or not they used marijuana before the age of 17, found that those who had used marijuana early had elevated rates of other drug use and drug problems later on, compared with their twins, who did not use marijuana before age 17. This study re-emphasizes the importance of primary prevention by showing that early drug initiation is associated with increased risk of later drug problems, and it provides more evidence for why preventing marijuana experimentation during adolescence could have an impact on preventing addiction.

1. That first paragraph there doesn't seem to sound like an anti-marijuana campaign really. I don't agree about the depression, anxiety, distrust, or panic. Fear just comes from fear of being caught.
2. Yes, it does affect your memory, but as made clear later on, it says it may not be permanent. And in fact it isn't permanent.
3. Marijuana is not addictive, physically or psychologically. Even daily users don't become addicted. They just use it a lot.
4. And that part about how 15% of drug rehab attendees were mostly pot smokers doesn't mean that pot was the only drug they did. They went for other drug problems, but pot was what they did most, not what they were addicted to.
Besides, some evidence for pro legalization and anti legalization can't really be proven. Both sides are at a stand still because we simply don't know everything about drugs. I don't care about heroin (bad), but all this about one of the least harmful illicit drugs isn't right.
