Marijuana caused more damage to teens’ brains than alcohol, study finds

Marijuana use may pose a greater risk to the developing brains of teenagers than alcohol consumption, according to a new study …

The analysis, published Wednesday in the American Journal of Psychiatry, found that cannabis had greater short and long-term consequences than alcohol on four key components of teens’ memory. The finding greatly surprised researchers.

“We initially suspected alcohol would have a bigger effect,” Patricia Conrod, lead author and professor of psychiatry at the University of Montreal told USA TODAY.

Researchers looked at four cognitive functions: Problem solving, long-term memory, short-term memory manipulation and the ability to stop a habitual behavior when needed. Marijuana had “significant” negative effects on all four, while the study could not tie alcohol to negative effects, Conrod said. …

Authors examined nearly 4,000 students in the Montreal region over four years, starting when the average participant was about 13 years old.

The students took yearly memory tests and self-reported their alcohol and marijuana use. …

The study found some of marijuana’s negative effects were short-term, while others were lasting.

A particularly troubling finding: Young cannabis users may cause long-term damage to a brain function associated with substance abuse. https://www.usatoday.com/story/news/nation-now/2018/10/06/marijuana-damaged-teenagers-brains-more-than-alcohol-study-finds/1539574002/

People should NOT smoke marijuana. It has many negative effects on the human body.

Short-term bodily effects of marijuana, Cannibis sativa

Various studies have shown that marijuana is frequently addictive and harmful.

The State of California hopes that it will make a lot of money because of marijuana, as do many California cities.

The Bible warns:

10 For the love of money is a root of all kinds of evil, for which some have strayed from the faith in their greediness, and pierced themselves through with many sorrows. (1 Timothy 6:10)

Notice what the National Institute of Health says about marijuana:

How Does Marijuana Affect the Brain?

When marijuana is smoked, THC rapidly passes from the lungs into the bloodstream, which carries the chemical to the brain and other organs throughout the body. It is absorbed more slowly when ingested in food or drink.

However it is ingested, THC acts on specific molecular targets on brain cells, called cannabinoid receptors. These receptors are ordinarily activated by chemicals similar to THC that naturally occur in the body (such as anandamide; see picture, above) and are part of a neural communication network called the endocannabinoid system. This system plays an important role in normal brain development and function.

The highest density of cannabinoid receptors is found in parts of the brain that influence pleasure, memory, thinking, concentration, sensory and time perception, and coordinated movement. Marijuana overactivates the endocannabinoid system, causing the “high” and other effects that users experience. These effects include altered perceptions and mood, impaired coordination, difficulty with thinking and problem solving, and disrupted learning and memory.

Marijuana also affects brain development, and when it is used heavily by young people, its effects on thinking and memory may last a long time or even be permanent. A recent study of marijuana users who began using in adolescence revealed substantially reduced connectivity among brain areas responsible for learning and memory. And a large long-term study in New Zealand showed that people who began smoking marijuana heavily in their teens lost an average of 8 points in IQ between age 13 and age 38. Importantly, the lost cognitive abilities were not fully restored in those who quit smoking marijuana as adults. Those who started smoking marijuana in adulthood did not show significant IQ declines.

What Are the Other Health Effects of Marijuana?

Marijuana use may have a wide range of effects, particularly on cardiopulmonary and mental health.

Marijuana smoke is an irritant to the lungs, and frequent marijuana smokers can have many of the same respiratory problems experienced by tobacco smokers, such as daily cough and phlegm production, more frequent acute chest illness, and a heightened risk of lung infections. One study found that people who smoke marijuana frequently but do not smoke tobacco have more health problems and miss more days of work than those who don’t smoke marijuana, mainly because of respiratory illnesses. It is not yet known whether marijuana smoking contributes to risk for lung cancer.

Marijuana also raises heart rate by 20-100 percent shortly after smoking; this effect can last up to 3 hours. In one study, it was estimated that marijuana users have a 4.8-fold increase in the risk of heart attack in the first hour after smoking the drug. This risk may be greater in older individuals or in those with cardiac vulnerabilities.

A number of studies have linked chronic marijuana use and mental illness. High doses of marijuana can produce a temporary psychotic reaction (involving hallucinations and paranoia) in some users, and using marijuana can worsen the course of illness in patients with schizophrenia. A series of large studies following users across time also showed a link between marijuana use and later development of psychosis. This relationship was influenced by genetic variables as well as the amount of drug used, drug potency, and the age at which it was first taken—those who start young are at increased risk for later problems.

Associations have also been found between marijuana use and other mental health problems, such as depression, anxiety, suicidal thoughts among adolescents, and personality disturbances, including a lack of motivation to engage in typically rewarding activities. More research is still needed to confirm and better understand these linkages.

Marijuana use during pregnancy is associated with increased risk of neurobehavioral problems in babies. Because THC and other compounds in marijuana mimic the body’s own endocannabinoid chemicals, marijuana use by pregnant mothers may alter the developing endocannabinoid system in the brain of the fetus. Consequences for the child may include problems with attention, memory, and problem solving.

Additionally, because it seriously impairs judgment and motor coordination, marijuana contributes to risk of injury or death while driving a car. A recent analysis of data from several studies found that marijuana use more than doubles a driver’s risk of being in an accident. The combination of marijuana and alcohol is worse than either substance alone with respect to driving impairment.

Inhaling or ingesting marijuana basically makes someone drunk.

The Bible repeatedly condemns drunkenness and activities associated with it:

18 And do not be drunk with wine, in which is dissipation; but be filled with the Spirit (Ephesians 5:18)

21 For the drunkard and the glutton will come to poverty (Proverbs 23:21)

11 But now I have written to you not to keep company with anyone named a brother, who is sexually immoral, or covetous, or an idolater, or a reviler, or a drunkard, or an extortioner — not even to eat with such a person. (1 Corinthians 5:11)

9 Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived. Neither fornicators, nor idolaters, nor adulterers, nor homosexuals, nor sodomites, 10 nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners will inherit the kingdom of God. 11 And such were some of you. But you were washed, but you were sanctified, but you were justified in the name of the Lord Jesus and by the Spirit of our God. (1 Corinthians 6:9-11)

13 Let us walk properly, as in the day, not in revelry and drunkenness, not in lewdness and lust, not in strife and envy. 14 But put on the Lord Jesus Christ, and make no provision for the flesh, to fulfill its lusts. (Romans 13:13-14)

Becoming intoxicated by marijuana is sinful and not something that Christians should do.

The increased acceptance of marijuana is not good.

There are more problems with marijuana than many wish to accept.

Mankind’s problems will not be solved by money.
