By Menara21 They can cause drowsiness and a feeling of relaxation but repeated use can lead to an increase intolerance. Cocaine is a stimulant that can produce feelings of euphoria, increased alertness and energy. It can also have dangerous effects such as rapid heart rate and increased blood pressure, however. It increases levels of available dopamine in the brain by preventing the chemical from being recycled back into cells.
How can I help someone with an addiction?
There’s not a single cause of addiction — it’s a very complex condition. A significant part of how addiction develops is through changes in your brain chemistry. Substance use can lead to a wide range of health effects, and these consequences often vary depending on the type of substance, duration of use, and individual vulnerabilities. The impacts can be immediate and severe or develop gradually over time. Alcohol was ranked the most harmful substance overall from the list of 20 considered but this took into account the widespread usage of alcohol as a legal and generally socially acceptable drug. The study aimed to quantify the harms done by different substances in the UK to both individuals and society.
Cocaine
The most addictive drugs—which include crack cocaine, crystal meth, and prescription opioids—are also accompanied by intense withdrawal symptoms that make it difficult to quit. Recent studies have found that frequent social network users believe that other users are happier and more successful than they are, especially when they do not know them very well in real life. Excessive social media use can not only cause unhappiness and a general dissatisfaction with life in users but also increase the risk of developing mental health issues such as anxiety and depression. Constantly comparing oneself to others can lead to feelings of self-consciousness or a need for perfectionism and order, which often manifests as social anxiety disorder. Social media use becomes problematic when someone views social networking sites as an important coping mechanism to relieve stress, loneliness, or depression. Social media use provides these individuals with continuous rewards that they’re not receiving in real life, so they end up engaging in the activity more and more.
What Is Dual Diagnosis in Addiction Treatment?
In rare cases, a caffeine overdose can result in death due to convulsions or irregular heartbeat. If you have high blood pressure (hypertension) or heart-related problems, ask your doctor if caffeine is safe for you to consume. The blood vessels in your brain become used to caffeine’s effects, so if you suddenly stop consuming this compound, it can cause a headache. Now most addictive drugs leading experts at Harvard Medical School are here to help you separate fact from frightening fiction about medical cannabis so you can make informed decisions. And, while there is a lot of positive talk about cannabis, there are risks—especially if you’re over 55. People taking high doses of CBD may show abnormalities in liver-related blood tests.
Caffeine gives you a boost of energy and may lower your risk of certain conditions. However, consuming too much can lead to less desirable effects, such as headaches, confusion, and high blood pressure. Some CBD manufacturers have come under government scrutiny for wild, indefensible claims — such as that CBD is a cure-all for cancer or COVID-19, which it is not. We need more research, but CBD is proving to be a helpful, relatively nontoxic option for managing anxiety, insomnia, and chronic pain. The Farm Bill removed all hemp-derived products, including CBD, from the Controlled Substances Act, which criminalizes the possession of drugs. In essence, this means that CBD is legal if it comes from hemp, but not if it comes from cannabis drug addiction treatment (marijuana) — even though it is the exact same molecule.
- It is often prescribed for severe pain but is also found in illicit drug markets.
- The most addictive substances are those that rapidly increase dopamine levels in the brain, reinforcing compulsive use.

How are addictions treated?
This can quickly lead to the brain being less sensitive to dopamine, meaning the user needs more and more cocaine for the same effect, often leading to dangerous ‘binges’. Among prescription pills, opioids like oxycodone, benzodiazepines like Xanax, and stimulants like Adderall are considered some of the most addictive medications. These pills are commonly misused for their calming, euphoric, or energy-boosting effects and frequently appear on lists of most addictive drugs due to their widespread abuse and high potential for dependency. Addiction isn’t just about choice — it’s a complex condition driven by chemical changes in the brain.
Substances such as methamphetamine, fentanyl, and nicotine can create an intense high followed by a crash, which encourages repeated use. The risk increases with drugs that cause strong physical dependence, quick tolerance buildup, and difficult withdrawal symptoms. Opioids differ from other drugs in how they affect dopamine levels, as they specifically attach to the GABA neurotransmitter, which controls the brain’s reward and pleasure pathway. Once the opioids slow down the GABA neurons, dopamine floods the brain’s pleasure circuits, resulting in a wave of pleasure and pain relief. These effects reinforce the idea in the brain that taking opioids is a rewarding experience, leading to increased use and addiction.
- This then causes people to engage in the social networking behavior even more as a way of relieving dysphoric mood states.
- Nicotine, found in tobacco and vapes, is also one of the most addicting drugs due to its rapid onset and widespread use.
- As one of the most powerful drugs available, it’s responsible for a growing number of overdose deaths worldwide.
The UNODC World Drug Report 2025 highlights increasing concerns about benzodiazepine misuse and dependence worldwide. If you struggle with an addiction to any of the most addictive substances listed here, know that the weight of addiction doesn’t have to hold you down any longer. In 1997, Former Director of the National Institute on Drug Abuse, Dr. Alan Leshner, suggested that addiction be defined as a “chronic, relapsing brain disorder” and, therefore, be viewed as a brain disease. Methadone treats more severe conditions that don’t respond well to non-opioid treatments.
Potential outcomes include liver disease, cardiovascular disease, chronic lung disease, renal damage, and various forms of neurologic injury. When it comes to Substance Use Disorder, some drugs take hold faster and tighter than most people realize. In this article, you’ll uncover the top contenders, the science behind their grip on the brain, and the surprising factors that determine just how quickly dependence can form. Crack cocaine, also known simply as crack, is a highly addictive ‘free base’ form of cocaine made by mixing powdered cocaine with baking soda.
If you or someone you know is struggling with addiction, seeking professional help is the best step toward recovery. Remember, there is always hope, and treatment is available for those who need it. Ironically, methadone is used to treat opioid addiction but is itself a highly addictive drug. While it helps reduce cravings and withdrawal symptoms for heroin users, it requires careful medical supervision to prevent a secondary addiction.
Most substances affect the brain, albeit in varying ways and levels of severity. Almost all addictive drugs impact the brain’s reward system and cause some disruption to the normal creation, flow, and release of dopamine, the neurotransmitter responsible for feelings of pleasure. An estimated 27% of children who spend 3 or more hours a day on social media exhibit symptoms of poor mental health. Overuse of social networking sites is much more problematic in children and young adults because their brains and social skills are still developing. Research has shown that adolescents who habitually use social media from a young age have severely stunted social interaction skills. Despite the fact that users are interacting with each other on these platforms, many of the these types of interactions don’t necessarily translate well to the real world.
