Step-by-step explanation:
The ranking of the drugs from least addictive to most addictive, among the given options, is most likely Marijuana, Nicotine, Cocaine, Heroin. Marijuana is commonly perceived as less addictive compared to nicotine, which is found in tobacco products and is considered highly addictive. Cocaine is a powerful stimulant known for its addictive potential, but Heroin, an opioid, is often considered one of the most addictive substances, in part due to the severe physical dependency it creates as well as the associated withdrawal symptoms.
Three toxic chemicals present in tobacco smoke are tar, carbon monoxide, and formaldehyde. To address a related matter, e-cigarettes can also be addictive, primarily due to the presence of nicotine. As for other substance use, the opioid crisis has highlighted the addictive nature and severe impact of opioid pain medications, including Heroin, Oxycodone, and Vicodin. Methadone is sometimes used to help people with heroin addiction because it acts on the same opioid receptors but is longer-lasting and less euphoric, helping to alleviate withdrawal symptoms and reduce cravings.
