addiction

Experts define addiction as continued marijuana use despite negative consequences in a person's life, such as issues relating to their family, job, or relationships.
People who use marijuana regularly and then stop abruptly can experience some withdrawal symptoms.

Some people think that marijuana is not truly “addictive” or that people can’t become “hooked” on the drug, but research shows that about 1 in 10 marijuana users will become addicted. For people who begin using before the age of 18, that number rises to 1 in 6.
Marijuana use directly affects the brain — specifically the parts of the brain responsible for memory, learning, attention, decision making, coordination, emotions, and reaction time.
 

In Ontario, for instance, a survey released Wednesday by the Centre for Addiction and Mental Health (CAMH) found that past-year cannabis use virtually doubled between 1996 and 2015, rising from about eight per cent to almost 15 per cent of respondents.
Significant increases were found among all age groups, but especially among 18- to 29-year-olds, with the proportion of pot smokers jumping from about 18 per cent in 1996 to 38 per cent in 2015

The illegal marijuana market thrives in competition with the legal market by offering products at considerably lower prices because it neither complies with regulations on growth and sale, nor pays taxes on sales or their profits. It is particularly disturbing that the public is unaware of the fact that of all Americans with substance use disorders due to drugs other than alcohol, nearly 60 percent are due to marijuana. That means that more Americans are addicted to marijuana than any other drug, including heroin, cocaine, methamphetamine, and the nonmedical use of prescription drugs.

A new study suggests marijuana smokers may be significantly more likely to develop an addiction to other drugs and alcohol than people who don’t use marijuana.
The study, published in JAMA Psychiatry, included almost 35,000 adults who were interviewed three years apart. At the time of the first interview, almost 1,300 used marijuana. After three years, two-thirds of people who used marijuana had some form of substance use disorder, compared with less than 20 percent of people who did not use marijuana in the previous year.

Arizona Families F.I.R.S.T., a statewide recovery program, found that 84 percent of program participants in 2014 struggled with substance abuse, 54 percent of which said they used marijuana

Brain abnormalities and memory problems were observed in these individuals in their early twenties, two years after they had stopped using marijuana. The cannabis users were noted to have striatal, globus pallidus, and thalamus changes showing these brain regions appearing to shrink and collapse inward. These individuals also had poorer working memory. The earlier the age of cannabis use, the more dramatic the brain changes and memory deficits were noted to be.
Not only does it appear that cannabis use itself is a potential precursor to future drug use, but the age of first use of cannabis and the frequency of cannabis use seem to also be predictors of future substance abuse issues. Studies have shown that over two-thirds of those under the age of 18 who have been admitted to a drug treatment program identify cannabis as their substance of choice.
” One important characteristic that defines a substance use disorder is “an underlying change in brain circuits that may persist beyond detoxification, particularly in individuals with severe disorder"

The Gazette kicks off a four-day perspective series, "Clearing the Haze," that examines health, social, regulatory and financial issues associated with the world's boldest experiment with legal marijuana. 
The ugly truth is that Colorado was suckered. It was promised regulation and has been met by an industry that fights tooth and nail any restrictions that limit its profitability. 

 Stuart Gitlow, MD, president of ASAM and a board-certified addiction medicine specialist, called the paper’s stance “irresponsible” and “ignorant of the facts” that clearly place marijuana on the continuum of psychoactive drugs that trigger addiction and lifelong chronic brain disease.

“I can share my personal weed with somebody, no problem,” said Taijeron. “But we can’t sell it or exchange money for marijuana.”

The reviewers consider areas in which little research has been conducted. This includes possible health consequences of secondhand marijuana smoke; the long-term impact of prenatal marijuana exposure; the therapeutic potential of the individual chemicals found in the marijuana plant; and effects of marijuana legalization policies on public health.

A new study suggests people with mental illness are more than seven times as likely to use marijuana weekly than people without a mental illness.

In total, 4.4 percent of individuals with a mental illness in the past 12 months reported using cannabis weekly, compared to 0.6 percent among individuals without any mental illness.

Cannabis use disorders occurred among 4 percent of those with mental illness versus 0.4 per cent among those without.

Researchers also noted that, although cannabis use is generally higher among younger people, the association between mental illness and cannabis use was pervasive across most age groups.

Kevin A. Sabet, the director of the Drug Policy Institute at the University of Florida and a former senior advisor for President Barack Obama's Office of National Drug Control Policy, also takes issue with this sweeping claim.   "Show me that data," Sabet said in reaction to hearing this. "Also, chocolate doesn't cause car crashes or IQ loss or mental illness."

Calvina Fay, executive director of Drug Free America, a nonprofit that educates the public about the dangers of drug abuse, responded, "Unlike marijuana, I am not aware of anyone in treatment for chocolate addiction and it certainly is not a substance that sends people to the hospital or impairs one's ability to work or operate a vehicle or machinery."

Furthermore, early users of all three substances were more than twice as likely to meet the criteria for marijuana dependence (21% vs. 8%).

• Florida should not legalize marijuana because it is a gateway drug that is addictive and damaging to the teenage brain. Moreover, without FDA regulation there is no way to monitor the drug’s potency.
• He then fell into the habit of taking pills in order to maintain the buzz he got from pot.
• It is out of love for our children, for those like my son, that we must say no (to legalizing marijuana).
