Probability of Transition From First Use to Dependence For Various Substances

"In a large, nationally representative sample of US adults, the cumulative probability of transition to dependence was highest for nicotine users, followed by cocaine users, alcohol users and, lastly, cannabis users. The transition to cannabis or cocaine dependence occurred faster than the transition to nicotine or alcohol dependence. Furthermore, there were important variations in the probability of becoming dependent across the different racial-ethnic groups. Most predictors of transition were common across substances.

Estimated Prevalence of Cannabis Dependence

Estimated Prevalence of Cannabis Dependence: "Some 4.3 percent of Americans have been dependent on marijuana, as defined in the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM-IV-TR; American Psychiatric Association, 2000), at some time in their lives. Marijuana produces dependence less readily than most other illicit drugs. Some 9 percent of those who try marijuana develop dependence compared to, for example, 15 percent of people who try cocaine and 24 percent of those who try heroin. However, because so many people use marijuana, cannabis dependence is twice as prevalent as dependence on any other illicit psychoactive substance (cocaine, 1.8 percent; heroin, 0.7 percent; Anthony and Helzer, 1991; Anthony, Warner, and Kessler, 1994)."

Social Determinants and Substance Use

Social Determinants and Substance Use: There is strong evidence of an association between social determinants—such as unemployment, homelessness, poverty, and family breakdown—and drug use. Socio-economic status has been associated with drug-related harms such as foetal alcohol syndrome, alcohol and other drug disorders, hospital admissions due to diagnoses related to alcoholism, lung cancer, drug overdoses and alcohol-related assault.

Admissions to Treatment for Marijuana in the US

According to the Substance Abuse and Mental Health Service's Treatment Episode Data Set, in 2015 in the US there were 213,001 admissions to treatment with marijuana reported as the primary substance of abuse out of the total 1,537,025 admissions to treatment in the US for those aged 12 and older for all substances that year. This is the lowest number of marijuana admissions and total treatment admissions in at least a decade: marijuana admissions peaked in 2009 at 373,338, and total admissions peaked in 2008 at 2,074,974.

Use of Alcohol, Tobacco, and Other Drugs by Young People

"Teen users are at significantly higher risk of developing an addictive disorder compared to adults, and the earlier they began using, the higher their risk. Nine out of 10 people who meet the clinical criteria for substance use disorders involving nicotine, alcohol or other drugs began smoking, drinking or using other drugs before they turned 18. People who begin using any addictive substance before age 15 are six and a half times as likely to develop a substance use disorder as those who delay use until age 21 or older (28.1 percent vs. 4.3 percent)."

History Of Ibogaine As Treatment For Substance Use Disorder In The US

"In 1962, the anti-addictive property of ibogaine was inadvertently discovered by 19-year-old heroin addict Howard Lotsof.58 Lotsof was part of an experimental group of mostly 20-something Caucasians attending college.59 The group, which included seven heroin addicts, shared a common interest in experimenting and subjectively evaluating their experiences with various psychoactive drugs, including Mescaline, LSD, DMT, and psilocybin,60 in an effort to determine the psychotherapeutic value of hallucinogenic drugs.61 As psychedelic drugs were not ill

Physical and Psychological Effects of Ibogaine in the Context of Addiction (Substance Use Disorder) Treatment

"Within three hours after ingesting a higher dose of ibogaine, the user will enter into the 'acute phase,' typically lasting four to eight hours.42 It is during this phase that the user experiences ibogaine’s most intense effects, characterized as the 'panoramic recall of a large amount of material relating to prior life events from long-term memory, primarily in the visual modality,' or the 'waking dream' state.43 If the user is an addict, he or she will usually be taken back to the place and time where the underlying issue leading t

Estimated Prevalence of Substance Use Dependence or Addiction in the US by Race/Ethnicity, According to NSDUH

"In 2015, approximately 20.8 million people aged 12 or older had an SUD in the past year, including 15.7 million people who had an alcohol use disorder and 7.7 million people who had an illicit drug use disorder (Figure 27). An estimated 2.7 million people aged 12 or older had both an alcohol use disorder and an illicit drug use disorder in the past year (Figure 28). Thus, among people aged 12 or older in 2015 who had an SUD in the past year, nearly 3 out of 4 had an alcohol use disorder, and about 1 out of 3 had an illicit drug use disorder.
